| Thermally Broken Aluminum Windows |
Hot, mixed, coastal, and modern commercial or residential projects where slim sightlines and structural strength are important. |
Double glazing commonly achieves approximately Uw 1.2–1.8 W/m²·K; triple glazing can improve performance to approximately Uw 0.8–1.2 W/m²·K, depending on the complete window design. |
Low-emissivity insulated glass with argon filling; thermally separated aluminum frame; powder-coated or anodized exterior finish. |
Requires accurate opening measurements, correct frame anchoring, perimeter insulation, drainage clearance, and compatible sealants. Coastal projects should specify corrosion-resistant finishes and hardware. |
Use corner protection, moisture-resistant wrapping, vertical or purpose-designed crates, and impact indicators. Large glazed units may require special handling equipment at destination. |
Common market practice is approximately 5–10 years for frames and 5–10 years for insulated-glass units, subject to written terms and maintenance requirements. |
Replacement gaskets, rollers, handles, locks, drainage covers, finish-care guidance, and access to compatible glass units. |
Request tested air, water, wind, thermal, and hardware-performance data for the exact configuration rather than for the frame system alone. |
| uPVC Tilt-and-Turn Windows |
Cold, temperate, and noise-sensitive residential buildings; suitable where thermal insulation and low maintenance are priorities. |
High-performance double glazing commonly falls near Uw 1.0–1.5 W/m²·K; triple glazing may reach approximately Uw 0.7–1.0 W/m²·K with suitable spacers and frame design. |
Multi-chamber uPVC profile, low-e double or triple insulating glass, warm-edge spacer, and multi-point locking hardware. |
Frames must be installed plumb, level, and square. Use mechanical fixings, perimeter air sealing, insulated expansion gaps, and sill drainage. Avoid relying on foam alone as the structural fixing method. |
Protect corners and hardware from abrasion; prevent prolonged direct sunlight on wrapped units during transit; separate glass surfaces to reduce scratching and condensation risk. |
Typical written coverage is approximately 5–10 years for frames and hardware, with separate terms often applying to sealed glass units and moving parts. |
Adjustment instructions, replacement hardware availability, drainage cleaning guidance, and support for condensation or operating issues. |
Confirm resistance to local ultraviolet exposure, temperature variation, wind loads, and national fire or egress requirements. |
| Timber-Aluminum Composite Windows |
Cold and temperate climates, premium homes, heritage-sensitive projects, and buildings requiring an interior timber finish with exterior weather protection. |
Typical complete-window performance is approximately Uw 0.8–1.4 W/m²·K, depending on timber depth, glazing, spacers, and opening size. |
Engineered or laminated timber interior, ventilated aluminum exterior cladding, low-e double or triple glazing, and moisture-managed joints. |
Requires careful moisture control, compatible sill detailing, accurate shimming, and protection of finished timber surfaces. Installation should follow the manufacturer’s approved sequence. |
Needs rigid crates, dry storage, edge protection, and strict control of humidity and condensation. Finished timber surfaces should not remain exposed to wet construction conditions. |
Common warranty periods are approximately 5–10 years for the window assembly; coatings and moving hardware may have separate conditions. |
Periodic coating inspection, cleaning instructions, hardware lubrication, replacement seals, and guidance for indoor humidity control. |
Check allowable indoor humidity, exterior coating-renewal intervals, timber species, moisture content, and local preservation requirements. |
| Insulated Steel Security Doors |
Apartment entrances, commercial buildings, utility rooms, high-traffic areas, and projects requiring enhanced security or fire performance. |
Thermally insulated models commonly provide approximately Ud 1.0–1.8 W/m²·K; uninsulated steel doors perform substantially worse thermally. |
Galvanized or coated steel leaf, mineral-wool or rigid insulation core, multi-point lock, adjustable hinges, and compression seals. |
Requires a structurally sound opening, correct threshold support, accurate hinge-side alignment, and adequate anchoring. Fire-rated installations must use the complete tested door-set configuration. |
Protect thresholds, lock cylinders, corners, and powder-coated surfaces. Door leaves should be secured against movement inside the crate to prevent hinge and frame damage. |
Typical coverage is approximately 2–5 years for hardware and finish, while fire and security ratings depend on maintaining the certified configuration. |
Lock-cylinder replacement, closer adjustment, seal replacement, threshold repair, and local availability of access-control components. |
Verify tested security, fire, smoke-control, acoustic, and weather-performance classifications required by the destination building code. |
| Insulated Fiberglass or Composite Exterior Doors |
Humid, coastal, mixed, and high-maintenance-sensitive residential applications where resistance to moisture and dimensional movement is important. |
Typical complete-door performance is approximately Ud 1.0–1.8 W/m²·K, depending on leaf thickness, glazing area, frame, and threshold. |
Fiberglass or composite skin, insulated core, moisture-resistant frame, weather seals, and low-e safety glazing where required. |
Threshold must be fully supported and correctly flashed. The frame should be square and secured at hinge and strike points; exterior joints require compatible weatherproof sealant. |
Use padded crates and moisture barriers. Avoid stacking heavy materials on door leaves or exposing unfinished components to standing water during storage. |
Common market practice is approximately 5–10 years for the door system, with shorter or separate coverage for glass, finish, locks, and accessories. |
Replacement weather-stripping, hinge and lock adjustment, finish-care instructions, threshold parts, and troubleshooting for air or water leakage. |
Check water penetration testing, ultraviolet resistance, local hardware compatibility, and whether the warranty covers coastal or high-humidity locations. |
| Lift-and-Slide Patio Doors |
Large openings, premium residences, hospitality projects, and warm or temperate climates where wide views and smooth operation are required. |
Typical complete-door performance is approximately Uw 1.0–1.8 W/m²·K; performance decreases as panel size and glass area increase. |
Thermally broken aluminum, composite, or reinforced uPVC frame; low-e insulating glass; stainless or corrosion-resistant rollers; multi-point locking. |
Requires very accurate sill level, structural support beneath the track, allowance for building movement, and careful water-management detailing. Large panels often require lifting equipment. |
Confirm maximum crate dimensions, gross weight, container loading plan, lifting points, and destination access. Glass panels should be transported upright and secured against vibration. |
Typical coverage is approximately 5–10 years for frames and insulating glass, while rollers and hardware may have separate terms. |
Track cleaning, roller replacement, lock adjustment, seal replacement, and rapid support for drainage or alignment problems. |
Obtain maximum panel dimensions, operational-force data, water drainage details, spare-part lead times, and site-access requirements before ordering. |
| Fire-Rated Windows and Doors |
Stairwells, corridors, compartment walls, healthcare, education, industrial, and high-rise applications where life-safety compliance is mandatory. |
Thermal performance varies widely; fire resistance is normally stated by a tested classification such as 30, 60, 90, or 120 minutes, subject to the exact assembly. |
Certified fire-resistant glazing, steel or specially engineered framing, intumescent materials, approved hardware, and compatible seals. |
Must be installed exactly within the scope of the relevant test or assessment. Site modifications, unapproved hardware, incorrect gaps, or unsuitable fixings can invalidate the rating. |
Use traceable labels, protected storage, shock-resistant packaging, and documented inspection upon arrival. Keep certification and installation records with the project file. |
Warranty is commonly approximately 1–5 years, but certification validity depends on correct installation, approved components, and required inspection or maintenance. |
Scheduled inspection, closer and latch testing, seal checks, replacement of certified components, and retention of compliance documentation. |
Confirm the destination country’s fire-test standard, classification, glazing limits, maximum sizes, hardware scope, and installer qualification requirements. |
