Villas, high-rise residences, public buildings and commercial spaces.
Scope：3,200㎡ / 21 floors
Full facade replacement for a 21-storey Grade-A office tower using factory-assembled unitized curtain wall panels. Engineered to Taiyuan's 50-year wind load with Class 5 wind resistance; Low-E insulated glass cut the building's cooling and heating load by roughly 18%.
Scope：3,800㎡ curtain wall
The headquarters brief balanced a solid corporate image with controllable life-cycle cost. Stone and glass are combined, with stone panels on undercut anchors so individual units can be replaced; double-silver Low-E insulating glass balances winter gain against summer shading, meeting targets for both image and energy.
Scope：46 units / steel + thermal-break roof
Many Jincheng homes have courtyards the owners want as usable living space. Thermal-break aluminium structures with laminated safety-glass roofs, perimeter opening vents and motorised shading create convection, so the space works in winter and stays cool in summer.
Scope：240 units / 33dB reduction
Heavy vehicle traffic on the riverside expressway produced pronounced low-frequency noise. Asymmetric insulating glass with a PVB interlayer damps low-frequency resonance, profile chambers are filled with acoustic wool and a triple seal was applied, cutting night-time bedroom noise from 66dB to 33dB.
Scope：150 units / Class 6 wind load
Holiday apartments face open sea winds where typhoon pressure governs. Reinforced mullions and multi-point locking meet Class 6 wind resistance, sash corners use injected brackets and glazing is laminated insulated; two typhoons later there is no deformation or leakage on record.
Scope：200 units / thermal-break systems
Early single-glazed aluminium windows caused heavy winter condensation. All were replaced with multi-chamber thermal-break systems and insulating glass; warm-edge spacers replacing aluminium ones markedly reduced edge condensation. Work was done from inside with safety netting, avoiding large lifting equipment.
Scope：170 units / thermal-break systems
A decade after handover, seals had aged and hardware jammed. Multi-chamber thermal-break systems with adjustable lock points ease future maintenance; interior removal with rope access was used, with certified crews on twin-rope protection.
Scope：310 units / thermal-break replacement
1990s brick-concrete housing with corroded steel windows and severe winter draughts. An insert-window technique avoided removing existing frames, minimising damage to finishes; a dedicated adapter profile bridges old and new, keeping per-unit work inside a single day so residents need not move out.
Scope：210 units / PVDF + 316 hardware
Within 300 metres of the shoreline, salt mist seized hardware within two years. Profiles were upgraded to three-coat PVDF, all hardware to 316 stainless and fasteners to Dacromet; a three-year reinspection found handles and stays still operating smoothly without corrosion.
Scope：180 units / thermal-break windows
A 15-year-old high-rise where ageing PVC windows caused condensation and drafts. After per-unit measuring, all windows were replaced with 70-series thermal-break aluminium systems with double glazing and EPDM gaskets. Condensation was eliminated and indoor temperature rose by an average of 2.4℃ in winter.
Scope：270 units / airtightness Class 6
Housing near the industrial zone had long suffered from dust. Beyond window replacement, openable sashes were emphasised with triple sealing and adjustable compression lock points, plus removable screens for easy cleaning; dust on sills fell by roughly 80%.
Scope：240 units / airtightness Class 6
Housing beside a coal haul route suffered persistent fine dust ingress. Alongside full replacement, sash sealing was emphasised with triple seals and adjustable compression locks plus removable screens; indoor settled dust dropped noticeably, reducing cleaning frequency.
Scope：150 units / tilt-and-turn
A high-rise in the old city centre with a cramped site and limited crane access. Removal and installation were done from inside with rope assistance, and old frames were bagged for disposal. Tilt-and-turn systems eliminate the fall hazard of outward-opening sashes at height.
Scope：32 villas / wind + debris resistance
Detached villas face typhoon-borne debris impact. Laminated glazing with heavy-duty multi-point locks and an extra mid-height keep on large sashes; every unit underwent open/close and locking force testing before handover, with typhoon-season usage and reinforcement guidance issued.
Scope：260 units / full replacement
Multi-storey brick-concrete blocks in a municipal retrofit programme, where window openings varied widely. Every unit was measured individually and each window custom-built. Foam plus weather-resistant sealant formed a dual seal; overall U-value dropped from 4.7 to 2.2 W/(㎡·K).
Scope：34 villas / system windows + sliding doors
The villa brief was detailed about sash size, colour and hardware feel. Lift-and-slide doors connect to the courtyard, with 180kg leaves still operable single-handed; a uniform grey fluorocarbon finish coordinates with stone and timber, making the house a reference within the estate.
Scope：52 classrooms / safety restrictors
Outward-opening steel classroom windows posed collision and fall hazards. Tilt-and-turn replacements carry restrictors and anti-trap strips with laminated glass in lower fixed zones; all work was completed over the summer holidays, with ventilation and formaldehyde testing before term.
Scope：180 units / 34dB reduction
Less than 80 metres from the railway, with passing trains peaking at 78dB. For this intermittent high-level noise, laminated insulating glass and heavy-duty sealing were specified, with elastic frame-to-opening connections reducing structure-borne sound; indoor peaks dropped below 44dB.
Scope：190 rooms / 34dB reduction
The resort needed quiet without losing sea views or ventilation. Laminated insulating glass provides acoustic and safety performance, multi-point locks improve closed-state airtightness, and block-by-block works kept the hotel trading; guest noise complaints fell clearly.
Scope：120 units / 32dB reduction
Measured night-time traffic noise of 68dB beside a main arterial road. Asymmetric insulating glass panes with PVB interlayer, multi-layer sealing and deeper profile chambers brought indoor night noise below 36dB, meeting the stricter bedroom requirement of the national sound insulation code.
Scope：46 villas / system windows + sunrooms
A low-density villa cluster demanding lake views and refined elevations. Slim 45mm sightline system windows with 6+12A+6 double-silver Low-E glass; lake-facing elevations use thicker profiles and enhanced anti-corrosion treatment for large-span wind resistance.
Scope：96 dormitories / restricted ventilation
Dormitory windows posed both safety and winter heat-loss problems. Tilt-and-turn systems with restrictors allow long-term ventilation at a limited opening width; all work was completed within a 25-day summer window and passed formaldehyde and ventilation testing before term began.
Scope：30 villas / system windows + lift-slide doors
Villa owners prioritise views, finish and quiet. Slim-line systems carry large panes, with lift-and-slide doors linking living room to courtyard; concealed hinges from a single hardware family keep elevations clean while meeting airtightness and acoustic targets.
Scope：64 classrooms / safety restrictors
On-campus work was limited to school holidays, making the schedule rigid. All measuring and fabrication were completed in advance, and 64 classrooms were refitted within 30 days. Restrictors and anti-trap strips were fitted throughout, and daylight factor improved by about 25%.
Scope：380 units / wind + corrosion resistant
Open sea-facing balconies were constrained by both typhoons and salt mist. Reinforced balcony windows with fixed lower panels and sliding uppers were standardised, with hardware and fasteners specified for coastal exposure; the space is now usable year-round while retaining original railings.
Scope：280 units / clean + easy-clean
The inpatient retrofit balanced infection control with patient comfort. Frames use rounded internal corners and seamless welding with antibacterial-coated handles; openers are restricted against misuse and screens are removable. Work rolled through wards without any ward closure.
Scope：2,600㎡ glass curtain wall
The hotel retrofit aimed to lift street presence and cut cooling load. Double-silver Low-E insulating curtain wall with a 0.38 shading coefficient was used; vertical fins conceal fixings and interior lighting is coordinated with coating reflection, making it a local landmark.
Scope：220 units / clean + airtight
With heavy outpatient flow and strict infection control, frames use seamless welding and rounded internal corners for easy wiping; openers carry removable screens and restricted ventilation. Work advanced zone by zone with outpatient services running normally throughout.
Scope：28 units / shading + forced ventilation
Heat build-up is the core issue for tropical sunrooms. Thermal-break roofs with Low-E laminated glass, large perimeter openings for cross ventilation, plus motorised shading and mechanical extract keep midday temperatures about 8℃ below a conventional sunroom.
Scope：5,400㎡ facade / 1,600㎡ skylight
A station-front retail complex with heavy footfall and strict fire compartmentation. Facade and skylight were detailed together; all glass is heat-soak tested tempered to reduce spontaneous breakage, with condensation gutters and maintenance walkways on the skylight. Breakage stayed below 0.05% over two years.
Scope：420 units / whole building
In a decommissioned plant office, steel windows were heavily corroded. Thermal-break aluminium replacements preserve the facade character, keeping original grid proportions and sill lines; screens and shading were renewed together, and the building now serves as the park's showcase for investors.
Scope：260 units / clean + airtight
The outpatient retrofit balanced infection control, cleanability and ventilation. Frames use rounded internal corners and seamless welding with antibacterial-coated handles; openers have limited ventilation angles and removable screens, with zoned works keeping clinics open.
Scope：52 units / thermal-break roof
Linfen's wide seasonal swing makes sunrooms overheat in summer and freeze in winter. The roof uses a thermal-break structure with Low-E laminated glass, while motorised shading and opening vents create convection; indoor-outdoor difference reaches 7℃ at summer noon and the space stays usable in winter.
Scope：260 units / thermal-break systems
High-rise seaview units lacked airtightness and leaked during typhoons. Multi-chamber thermal-break replacements with sill flashings and weather sealing give two waterproofing lines; interior work with cradles completed the swap without enclosing balconies.
Scope：340 wards / clean windows
Inpatient building retrofit for clean zones requiring easy cleaning, no dead corners and high airtightness. Frames use rounded internal corners and seamless welding; hardware carries an antibacterial coating and openers are fitted with restrictors to control ventilation angles for infection control.
Scope：26 units / thermal-break + motorised shading
Roof-terrace additions must address waterproofing, insulation and compliance. A lightweight thermal-break structure limits load, the roof uses laminated safety glass with motorised shading, and two waterproofing terminations were detailed at the existing walls; a 24-hour water test showed no leakage.
Scope：290 units / thermal-break replacement
Openings vary and walls are friable in these older blocks. Every unit was measured and each window bespoke; decayed sills were reinforced before installation, with exterior weather sealant and interior sealant forming dual waterproofing. Winter room temperature rose by 2.7℃ on average.
Scope：18 units / motorised sectional doors
Large workshop openings see constant forklift traffic. Double-skin insulated sectional doors with safety airbags and infrared anti-trap were installed, with bottom seals tolerant of uneven floors. At roughly 200 cycles a day, hardware and track wear stayed within normal limits after a year.
Scope：3,400㎡ transparent glazing
The lobby brief demanded uninterrupted sea views. Large transparent panels with concealed horizontal fins reach 3.0m × 6.0m; glass is heat-soak treated for typhoon negative-pressure cases, and openable sections auto-lock under wind-pressure sensing.
Scope：86 classrooms / tilt-and-turn
A teaching building with heavy daily use and limited maintenance staff, so durability came first. All classroom windows were converted to tilt-and-turn, tilting inward 15° to avoid draughts across desks while keeping rain out if left open. Covered by a three-year campus inspection plan.
Scope：140 rooms / 33dB reduction
Facing an arterial road with night freight, the hotel needed mid- and low-frequency control. Laminated insulating glass with asymmetric panes, deeper chambers and multi-layer sealing were used; rolling floor-by-floor work kept the hotel trading, and complaint rates fell markedly.
Scope：16 units / motorised sectional doors
Large workshop openings need both insulation and wind resistance. Double-skin insulated sectional doors with wind ribs and infrared anti-trap were fitted, with bottom seals tolerant of uneven floors; at about 160 cycles a day the doors ran smoothly with no abnormal noise after a year.
Scope：1,200㎡ glass curtain wall
The lobby brief called for transparency and night-time presence. Large transparent panels with concealed vertical fins were used, the biggest at 2.8m × 4.5m requiring suction-cup rigging; interior lighting and coating reflection were coordinated to make the hotel a local landmark after dark.
Scope：6,800㎡ curtain wall
A high-traffic retail complex with heavy cooling load uses double-silver Low-E insulating curtain wall at a 0.32 shading coefficient; the skylight has motorised shading and condensate collection. Cooling energy came in about 15% below comparable projects.
Scope：38 units / steel + thermal-break roof
Penthouse owners frequently add sunrooms, with recurring complaints of summer overheating and winter leakage. Thermal-break aluminium roofs with laminated safety glass, a minimum 5% roof pitch, dual drainage paths and hidden perimeter gutters; no leak was recorded through a full rainy season.
Scope：1,100 windows / U-value 2.1
The occupied office building had to finish before the heating season. Factory prefabrication with rapid site installation averaged 40 minutes per window; the U-value fell to 2.1 W/(㎡·K) and first-season heat consumption dropped about 19% year on year.
Scope：380 units / shading + acoustic
Severe west solar gain and road noise were the drivers. Solar-control Low-E insulating glass with a 0.40 shading coefficient and 0.52 visible transmittance, plus argon filling and multi-layer sealing, cut west-facing afternoon peaks by about 3.5℃.
Scope：280 units / U-value 2.0
Residents of a district-heated estate complained of hot radiators but cold rooms. Diagnosis traced the largest heat loss to windows; replacement with 70-series thermal-break frames and double-silver Low-E insulating glass brought the U-value to 2.0 W/(㎡·K) and raised room temperature by about 3℃ on the same heat supply.
Scope：70 classrooms / ventilation + wind
Classrooms rely on natural ventilation yet must close reliably in typhoon season. Large openers with multi-point locks achieve airtightness and wind-load targets when shut; removable stainless screens resist salt mist, and all replacement plus ventilation testing was done over the summer.
Scope：210 units / Class 5 wind load
Open riverfront exposure brings high gust loads that deformed sashes and released locking points. The retrofit specifies reinforced mullions and multi-point locking to Class 5 wind resistance, with injected corner brackets at all four sash corners and per-unit open/close force testing at handover.
Scope：6,200㎡ daylight bands
Poor illumination was hurting quality inspection. Side daylight bands and roof lights were added using insulated polycarbonate with UV coating; motorised vents create natural ventilation, cutting workshop temperature by about 3℃ in summer along with lighting energy.
Scope：20 rooms / restrictors + rounded corners
Within children's reach, trapping and falling risks had to be removed. Openers use key-lockable handles and restrictors, lower fixed panes are laminated and all internal corners radiused; doors have anti-trap strips and kick plates, with item-by-item sign-off by the kindergarten.
Scope：190 units / airtightness Class 6
Seasonal dust drives frequent complaints about indoor grit. Beyond replacing windows, the frame-to-wall joint was the focus: foam filling plus exterior weather sealant and interior sealant forming a dual barrier. Airtightness reached Class 6 and settled dust dropped noticeably.
Scope：240 units / clean + mould resistant
High humidity encouraged mould around frames, an infection-control risk. Seamless welded frames with rounded internal corners allow disinfection, sealants are mould-resistant and openers are restricted; zoned works avoided any ward closure.
Scope：1,400 windows / whole building
The occupied office building had to stay functional throughout. Work was phased floor by floor with night-time close-out: removal, installation and sealing after hours, normal office use by day. Airtightness reached Class 6 and heating-season consumption fell by about 21%.
Scope：48 units / heavy-duty floor-spring doors
Street-facing shops open constantly and suffer winter draughts. Heavy-duty floor springs with twin brush seals and perimeter draught strips were used; door finishes match the street's overall character, balancing durability with comfort at the threshold.
Scope：5,100㎡ facade + skylight
A complex facade geometry on a tight programme was handled with factory-prefabricated unitised panels, site hoisting running parallel to structural works and cutting roughly 30 days from the programme; skylight glass is heat-soak treated with maintenance walkways.
Scope：28 villas / large openings
Courtyard villas emphasise indoor-outdoor flow and need large openings. Reinforced mullions and heavy-duty stays support 1.8m wide sashes, with multi-point locking ensuring airtight closure; hidden bottom drainage handles storms without spoiling the look.
Scope：160 rooms / acoustic + thermal
A decade-old seaview hotel struggled with noise and west-facing heat. Block-by-block work kept it operating; laminated insulating Low-E glass delivered both acoustic and thermal performance, raising comfort scores while lowering energy use.
Scope：8,600㎡ daylight bands
Ageing daylight bands had lost most of their transmittance. Replaced with insulated polycarbonate panels on aluminium framing; the roof vents were motorised and linked to smoke detectors for fire exhaust. Daytime lighting is now largely unnecessary in main work areas, saving about 110,000 kWh a year.
Scope：160 units / restrictors + fall protection
Repeated reports of children climbing raised safety concerns. While keeping ventilation, all openers received key-lockable handles and 90mm restrictors; reachable lower-floor panes use laminated glass, and usage notes plus in-home checks were provided.
Scope：640 units / airtightness Class 6
With heavy public flow, the service hall needed quiet, daylight and low upkeep. Large fixed panels with a few openers reduce maintenance, and a facade access track was reserved; zoned floor-by-floor works kept counters open all day.
Scope：460 units / shading + acoustic
The building faced both west-facing solar gain and road noise. Solar-control Low-E insulating glass with a shading coefficient of 0.42 keeps visible transmittance at 0.55; argon filling in the cavity lowered west-facing afternoon peak temperatures by roughly 4℃.
Scope：1,900㎡ curved curtain wall
The club's curved geometry means no two panels match. 3D scanning verified structural deviations before per-panel modelling and ordering, with adjustable brackets absorbing tolerance; all seaward fixings are 316 stainless to the highest salt-mist standard.
Scope：168 rooms / 35dB reduction
A long-established hotel on a main road with persistent noise complaints. Rolling floor-by-floor work kept the hotel operating throughout; laminated insulating glass and heavier sealing cut guestroom noise from 55dB to 34dB with no interruption to occupancy.
Scope：7 branches / unified identity
Bank branches need a consistent image with high security. Lobby glazing uses anti-attack laminated glass with concealed security grilles, entrances are sensor-driven automatic sliding doors, and all seven branches share colour and signage positioning for a coherent brand identity.
Scope：330 units / uniform enclosure
Mismatched balcony enclosures hurt both the elevation and resale value. The property manager standardised material, colour and grid under a three-year warranty, keeping original railings as inner protection and concealing drainage to avoid streaking.
Scope：18 rooms / restrictors + rounded corners
Windows in activity areas sit only 500mm above floor level, making falls the primary risk. Openable sashes were raised above 1.4m with key-lockable handles, lower fixed panes are laminated, all reachable corners are radiused and guardrails are integrated, with item-by-item sign-off by the kindergarten.
Scope：220 units / airtightness Class 6
Persistently high indoor humidity caused mould at walls and window edges. Beyond replacement, joint sealing and drainage were prioritised: exterior weather sealant, interior mould-resistant sealant, and per-unit verification that drainage holes and chamber paths are clear.
Scope：12 entrances / laminated glass
Garage entrances suffered rainwater backflow and winter icing. Steel-framed laminated glass canopies with a 6-metre span were installed, with gutters tied into site drainage. The 6+1.14PVB+6 build-up holds together even if the glass breaks, preventing falling fragments.
Scope：14 units / cold-store doors
Cold-chain storage demands insulation and defrost reliability. Doors use polyurethane foam between stainless skins, frames carry heater cables to prevent icing and jamming, and the bottom seal is a replaceable strip to keep maintenance affordable.
Scope：5,400㎡ daylight bands
Yellowed ageing daylight bands left the factory underlit. Insulated polycarbonate on aluminium framing replaced them, with motorised roof vents linked to smoke detectors for exhaust; main work areas now need little daytime lighting, saving about 90,000 kWh a year.
Scope：9 stores / automatic sensor doors
A retail chain needs a uniform look and fast fault response. Door colour and logo etching position were standardised, and floor springs and sensors share a single specification for interchangeable spares; a 24-hour response mechanism keeps average recovery within 6 hours per store.
Scope：44 villas / lift-and-slide doors
Owners wanted living room and terrace fully connected. Lift-and-slide doors deliver a 4-metre opening with 220kg leaves that still glide easily; hidden bottom drainage is step-free, and closed-state airtightness and wind resistance meet typhoon requirements.
Scope：24 classrooms / restrictors + anti-trap
Child safety governed every decision: key-lockable handles with 90mm restrictors allow ventilation only, all internal corners are radiused, and guardrails are integrated into the frames. Handover followed a safety checklist signed off by the kindergarten and parent representatives.
Scope：4,600㎡ large-panel glazing
The exhibition centre needed large transparent spans and speed. Semi-unitised panels up to 3.2m × 5.6m were installed with a compact crane and powered suction lifters; calculations account for Changzhi's basic wind pressure and include movement joints for thermal expansion.
Scope：36 units / folding + sliding doors
Restaurant strips want indoor-outdoor flow without losing winter warmth. Large folding doors with double glazing seal well when closed and open the whole frontage; bottom tracks are step-free for accessibility while keeping the street's character.
Scope：320㎡ large fixed glazing
The service hall needs daylight, quiet and low maintenance. Large fixed panels with a few openable sashes keep sightlines open while reducing the number of serviceable vents; a facade access track on the fixed zones makes high-level cleaning safe and controlled.
Scope：4,200㎡ facade + shading
Extensive glazing drove cooling load. Double-silver Low-E insulating glass with external aerofoil shading achieves a combined shading coefficient of 0.28; large areas are heat-soak treated and a facade access track was reserved for maintenance.
Scope：56 units / floor-spring doors
Shopfront doors on a pedestrian street open constantly, so hardware life drove the specification: heavy-duty floor springs and stainless-clad leaves rated for roughly a thousand cycles a day, with a ramped bottom rail for wheelchair and elderly access.
Scope：480 units / uniform enclosure
Owner-installed enclosures in a new estate risk elevation chaos and leak disputes. The developer organised a single scheme with unified material, colour and grid covered by warranty; original railings remain as inner protection and no leakage complaints followed.
Scope：62 entrances / face + remote
Access control had become nominal with doors permanently propped open. Stainless leaves with face recognition and remote opening retain mechanical keys and manual operation on power loss; connected to the property platform, propped-open doors fell by about 88%.
Scope：360 units / uniform enclosure
Individually enclosed balconies had left the elevation chaotic. The property manager ran a single tender with one design and colour, retaining original railings and standardising the grid by storey module. The facade is now visibly tidier and provides uniform access for future external repairs.
Scope：58 entrances / wind + face recognition
Coastal entrance doors were regularly blown open and damaged. Reinforced stainless leaves with closers and hold-open locks integrate face recognition and card access, retain manual opening on power loss, and add temporary storm bolts in typhoon season; damage dropped to zero.
Scope：4,100㎡ double-curved facade
The double-curved venue facade has no two identical panels. 3D scanning verified structural deviations and every panel was numbered from the model; adjustable brackets absorbed on-site tolerance, holding joint deviation within 3mm and keeping the curvature smooth.
Scope：22 points / plate + face recognition
Mixed vehicle and pedestrian flows slowed the industrial park. Entrances received plate recognition and facial-recognition turnstiles, with manual operation retained on power loss; integration with the park platform enables visitor pre-registration and audit trails, improving management efficiency.
Scope：120 rooms / low handles
Residents have limited mobility, so operating force and warmth matter most. Low handles and light stays keep operating force under 30N, Low-E insulating glass reduces winter cold radiation, and all corners are radiused with guard rails fitted.
Scope：1,400㎡ partitions
The on-site office block needed acoustic separation, fire rating and speed. Steel-framed fire-rated glazed partitions give a one-hour rating; partitions and doorset systems were supplied in matched finishes, cutting programme time by about 40% versus masonry and allowing flexible reconfiguration.
Scope：12 venues / folding doors
Seaview dining wants full opening yet must handle sudden squalls. Heavy-duty folding doors with insulating glass stack entirely when open and seal to wind-load standards when closed; 316 stainless hardware suits the coastal environment and slides smoothly.
Scope：32 openings / automatic sliding doors
Serving mainly elderly visitors, safe and effortless access was essential. Main entrances use sensor-driven automatic sliding doors with opening force below 25N and anti-trap rebound, plus low handles and slip-resistant thresholds for step-free wheelchair passage.
Scope：88 rooms / low handles
Care facilities prioritise low effort, safety and warmth. Low-level handles and light-duty stays reduce operating force, Low-E insulating glass avoids winter cold radiation, sills carry guard rails and all corners are radiused, with joint sign-off by the home and family representatives.
Scope：1,800㎡ facade + escape doors
With dense crowds, egress governed the design. A large-panel glass facade provides transparency while escape doors are sized by occupancy with panic bars that unlock automatically on power loss; all glass is heat-soak treated against spontaneous breakage.
Scope：230 units / multi-layer sealing
Spring sandstorms drive fine particles through window gaps. Rather than full replacement, the sealing system was upgraded: aged gaskets renewed, a third seal line added and locking points adjusted for compression. Far cheaper than new windows, and dust ingress was essentially eliminated.
Scope：170 units / 36dB reduction
Homes under the flight path see high take-off and landing peaks. Asymmetric laminated insulating glass damps broadband noise, supported by multi-layer sealing and acoustic chamber fill; indoor night noise fell from 64dB to below 38dB, meeting the stricter bedroom standard.
Scope：420 units / uniform enclosure
Open balconies were unusable in winter and too dusty for drying laundry. A uniform design with fixed lower panels and sliding upper sashes retains the original railings as inner protection; matching colour and grid lines markedly improved the estate's appearance.
Scope：1,600㎡ laminated glass canopy
Heavy pedestrian traffic at the station forecourt demanded a high safety class. A steel structure carries 8+1.52PVB+8 laminated glass with a minimum 3% drainage fall and concealed gutters; all panels are heat-soak tested and sampled at 1.5 times design load.
Scope：10 entrances / laminated glass
Garage entrances suffered rainwater backflow and winter icing. Steel-framed laminated-glass canopies with a 5.5m span feed gutters into site drainage; the 6+1.14PVB+6 build-up holds together if broken, preventing falling fragments.
Scope：54 entrances / face + card
Damaged entrance doors were routinely propped open. Stainless leaves with face recognition and card access were installed, retaining mechanical keys and manual operation on power loss; the system connects to the property platform for remote opening, cutting propped-open doors by 85% in six months.
Scope：34 openings / automatic sliding doors
Serving mainly elderly guests, low-effort and safe access came first. Sensor-driven automatic sliding doors open at under 25N with anti-trap rebound, thresholds are level for step-free wheelchair passage throughout.
Scope：68 entrances / face recognition
Access control retrofit for an older estate had to respect existing wiring and habits. Face recognition, card and remote opening are all supported, while the leaf retains mechanical escape operation and manual opening on power loss for fire egress. Propped-open doors fell by over 90%.
