3 casement windows from DERCHI's thermal-break 6063-T5 aluminum family deliver per-window customization for B2B project procurement. Each unit can carry independent dimensions, opening modes, glass configurations, and color finishes — suited for contractors and developers managing multi-room or multi-unit builds.
- Thermal-break 6063-T5 aluminum frame with PA66/DERCHI insulation strip
- 5+27A+5 mm double tempered insulated glass with argon fill
- WEHAG handle and hinge with two-point or six-point locking by series
- Outward casement, awning, cranked-out, or tilt-turn opening modes available
Product Details
The 3 casement windows draw from DERCHI's 109/118/127 mm frame depth family, using thermal-break 6063-T5 aluminum extrusions paired with PA66/DERCHI insulation strips. Unlike non-thermal-break profiles, the polyamide barrier interrupts conductive heat flow between interior and exterior aluminum faces, reducing thermal transfer across the frame assembly. Standard glazing is 5+27A+5 mm double tempered insulated glass with argon gas and a PVDF aluminum spacer, supported by EPDM sealing.
These aluminum casement windows adapt to bedrooms, living rooms, kitchens, bathrooms, balconies, and stairwells across residential and commercial projects. Opening modes include outward casement, awning, cranked-out, and inward/tilt-turn — each confirmed after drawing review. Style combinations range from single sash to three-segment, side-opening with center fixed, and irregular or bay-style configurations, giving project teams flexibility to match ventilation, spatial, and aesthetic requirements per window.

Advantages
Per-Window Customization: Each of the three units can carry separate dimensions, opening modes, glass packages, and color finishes — quote per window schedule.
Thermal-Break Performance: 6063-T5 aluminum with PA66 insulation strip supports energy-efficient envelope targets, reducing conductive heat transfer versus non-thermal-break frames.
Opening Flexibility: Outward casement, awning, cranked-out, and tilt-turn modes adapt to room function, ventilation needs, and spatial constraints across project areas.
WEHAG Hardware Partnership: Multi-point locking systems provide reliable operation and security for residential and commercial applications under daily use.
Export-Grade Packaging: Wooden-frame packaging with PE films, plastic belts, and air bags between pallets protects against sea-water exposure during international shipping.
Application Scenarios
Apartment: Compact urban units benefit from outward opening that saves interior floor space; thermal-break frames support energy targets for multi-unit residential developments where footprint efficiency matters.
Home Office: Sound insulation target of 35 dB helps maintain focused work conditions; glass upgrades such as frosted or reflective options add privacy and glare control for home workspaces.
Hotel: Color families from Pearl White to Deep Coffee coordinate with guest room interiors; WEHAG hardware withstands frequent daily operation across hospitality properties with high guest turnover rates.
Office Building: Low U-factor target supports commercial energy compliance; fixed glass combinations up to 12 m² suit large facade openings in corporate environments where daylighting and visibility matter.
Outdoor: 6063-T5 aluminum with EPDM sealing and 700 Pa water tightness target suits exposed enclosures — buyers should confirm weather resistance, wind pressure, and installation conditions per project.
Residential Building: Per-window customization lets developers specify different opening modes and glass packages for bedrooms, kitchens, bathrooms, and living areas within the same order, streamlining procurement across units.
Exterior: Frame depths from 109 to 127 mm offer structural flexibility for facade integration; wind resistance target of 5 KPa — confirm against project wind zone and floor level.
Villa: Wood grain finishes and fluorocarbon coatings match distinctive architectural styles; three-segment and bay-style combinations create character for villa elevations and feature rooms with custom design requirements.
