SCHÜCO AWS 90
The Schüco AWS 90 is a 90 mm deep aluminum window system designed for ultimate thermal performance, meeting and exceeding Passive House criteria in its class. It combines advanced insulation technology (foam-composite thermal breaks and triple seals) with the strength of aluminum, achieving Uf values as low as 0.7–0.8 W/(m²K). This results in superior energy efficiency for cold climates and a significant reduction in heating costs. Despite its thicker profile, the AWS 90 maintains elegant sightlines and offers various configurations (inward or outward opening, tilt-turn, etc.) for design freedom. Architects appreciate the system’s flexibility, which allows for large glass areas and even concealed-sash “block” window designs, resulting in minimal frame visibility. In short, AWS 90 delivers top-tier insulation and durability demanded in Canada’s West Coast environment, without sacrificing modern style.
Notable Features
Exceptional thermal insulation achieved with foam-insulated thermal breaks and triple sealing – keeping indoor temperatures stable and drafts out. Supports large triple-pane units for soundproofing, achieving up to 47–49 dB noise reduction, ideal for busy urban or coastal sites. Concealed hardware options and slim profiles (77 mm sightlines in AWS 90 BS) provide clean, modern aesthetics. The system is fully compatible with Schüco façades, doors, and smart home automation (e.g., TipTronic motorized opening) for integrated design.
Recommended Applications
Perfect for Passive House projects, net-zero homes, and high-performance retrofits in BC, where maximizing energy savings is a priority. Frequently used in luxury residences and penthouses for its combination of comfort and expansive views. Also suitable for institutional or commercial buildings (museums, universities, etc.) that demand premium thermal and acoustic performance. With proven air/water tightness, it excels in coastal and mountain climates – keeping heavy rain and wind at bay.
Key Specs
-
90 mm basic depth, part of Schüco’s modular 90 mm platform
-
Uf down to 0.71 W/(m²·K) (Super Insulation variant); achieves Passive House–level Uw ≈0.8 W/(m²·K) with triple glazing.
-
Up to 68 mm for thick triple glazing or acoustic panes
-
~99 mm standard; as slim as 77 mm in the AWS 90 BS concealed-sash configuration for maximal glass area
-
~1.7 m width × 2.5 m height operable vents (supporting large floor-to-ceiling windows)
-
Air permeability Class 4; Watertightness Class 9A (600 Pa); Wind resistance Class C5 (structurally rated for high winds); Burglar resistance up to RC3 (excellent security).
-
AWS 90 SI+ for maximum insulation, and AWS 90 BS.SI+ (Block System) for a flush, frameless exterior look with slightly reduced Uf (~0.96 W/m²K). Both variants support Passive House performance.
