Warm windows for low-energy and passive-standard projects
A warm window starts with depth. More frame depth means more chambers, more gaskets and room for thick triple glazing. RS Concept, a Polish window and door supplier, delivers deep, made-to-measure systems in three materials: PVC (85 mm, 6 chambers and 3 gaskets in the warmest version), thermally broken aluminium (frame 95 mm, sash 104 mm) and laminated wood (92 mm).
Supply only: installation is done by your own installer or contractor.
Three materials, one principle: depth
- PVC: deep 6-chamber systems with three gaskets and glazing units up to 52 to 54 mm. Lead time from 3 weeks.
- Aluminium: a thermally broken system for energy-focused projects, with glazing up to 71 mm in the frame and 81 mm in the sash. Lead time from 1 month.
- Wood: four layers of laminated timber, 92 mm deep, for projects that want a warm natural look inside. Lead time from 1 month.

The installation detail and an honest note
The window is only half of the result: the installation detail decides whether the numbers hold. We supply without installation, and we state glazing, spacer and technical data for the exact system in your quote.
Honest note: we do not label a window "passive house certified" unless the certificate of that exact system is part of your quote.
