Low Maintenance

This window won't be blighted by the issues that affected timber. Warping, cracking, bowing & twisting will be problems of the past. All these windows need is an occasional wipe with a damp cloth.

Reinforced Profile

The multi-chamber system achieves a WER A+ rating and can achieve U-values as low as 0.9 W/m2K using 24mm insulating glass units.

Ventilation

Controllable or permanent ventilators can be added into the head of the frame if required. This allows for a cooler property in the summer.

Foils & Colour
