Klearwall Windows

We have developed a timber vertical sliding sash window which is ideal either for the protected building where planning requires it or for the new build where traditional elegance is sought.

The Eco-Therm 58 range of windows and doors provides the strength and durability of aluminum coupled with a unique thermal break to achieve energy efficiency.

The PassiV AluClad window combines the strength, corrosion resistance, durability and recyclability of aluminum on the outside with the aesthetic advantages of a natural finish wooden window on the interior. Certified by the PassiV Haus Institute with values as low as 0.151 BTU/hr.ft2.F

Our PassiV Future Proof range was specifically engineered to make ultra low-energy windows generally accessible to all. The Future Proof range provides U-values as low as 0.134 BTU/hr.ft2.F – thermal performance that, until now, was typically available to but a privileged few. Now home owners, architects and builders can surpass building requirements and make buildings future-proof for years to come. See some examples of our products on our projects page.

The latest product suited to Landmark retrofits where energy performance and historical character are of equal importance.

The PassiV Aluminium window combines the structural strength, corrosion resistance, durability and recyclability of aluminium with a thermal performance which is suitable for use in Passive and A rated housing. This is a phenomenal achievement for any aluminium window.
