UPVC and Wood eco solutions

Meeting with sustainable codes of practice AsTec can provide window systems in UPVC and timber with innovative solutions that minimise the environmental impact to produce Stylish high rated energy efficient windows

• set to achieve energy ratings as low as 0.7 wm²/K
• we offer flush casement Tilt & Turn
• and fully reversible window systems.

High R-values – Low U-Values

To meet the requirements of the Passivhaus standard, AsTec can offer windows in UPVC and timber with exceptionally High R-values (low U-values, typically 0.85 to 0.70 W/(m².K) for the entire window including the frame).

These normally combine triple-pane insulated glazing (with a good solar heat-gain coefficient low-emissivity coatings, sealed argon or krypton Gas filled inter-pane voids, and ‘warm edge’ insulating glass spacers) with air-seals and specially developed thermally broken window frames.
