Thermal and sound insulation

The new generation uPVC windows are resilient to UV and can provide best thermal performance while remaining a good price option for house owners. These windows have been successfully tested to the most strict world performance standards and we have also obtained certification for NZS 4218:2009 (with a value up to R=1.39 which is over 5 times higher than the New Zealand standard). High sound insulation with reduction of up to 47dB (when combined with triple glazing).


Choose from multiple colour options with the possibility of different colours on the inside and outside. Custom shapes including round windows are also available.
