Overview
What makes the Alutrend Linear
stand out.
Alutrend Linear delivers the clean, flush aesthetic that modern architects demand - frame and sash sit perfectly aligned on the exterior for an uninterrupted facade. The air gap between the wooden frame and aluminum cladding acts as an additional thermal insulator. Available in four variants: Standard 68, XL 78, and Qube editions of both with angular inner sash strips for a contemporary interior. Three seal lines, double or triple glazing, and a full range of RAL or wood-decor aluminum exteriors with natural timber interiors.
Key Highlights
- Frame and sash flush-aligned on exterior for minimalist facade
- Qube variant with angular inner sash strip for modern interiors
- Air gap between wood and aluminum provides additional insulation
- Aluminum exterior in any RAL, NCS, or wood-decor finish
- Natural timber interior - pine, meranti, or oak
- Zero exterior wood maintenance - aluminum handles all weather
Ideal For
Modern and contemporary architecture where clean lines and flush facades are essential. Ideal for architect-specified custom homes, spec builds with a premium aesthetic, and any project where the exterior needs to look sharp with zero maintenance.
Consider an Alternative When
If you need better thermal performance, the Synergic offers Uw 0.78 with hidden sash technology and ultra-narrow sightlines. If you prefer a traditional exterior profile rather than flush, other Alutrend cladding shapes (Softline, Classic, Quadrat) are available on the same platform.
