Zero90 Passive House window system

uPVC Casement Windows

As the UK's first Passivhaus-certified uPVC casement windows, Zero|90 casements help to reduce carbon in the construction of homes and buildings. They are made sustainably in Britain, incorporate recycled components and are fully recyclable at the end of their useful life, meaning Zero|90 casements deliver whole-life carbon reductions.

Many other systems feature messy and time-consuming foam-filled cavities to meet the requirements.

The Zero|90 window range is unique in that its 9-chamber profile – 3 more chambers than Liniar EnergyPlus – has been designed to meet the triple challenges of thermal efficiency, noise reduction and security, achieving U-values as low as 0.5. Most uPVC window systems are limited to 40mm glazing options – however the Zero|90 window range offers triple glazing as standard, in a choice of 48mm or 56mm units.

There are almost endless combinations of glazing available for Zero|90, to suit every type of installation. Triple glazed units can incorporate Pilkingtons Optiphon or Saint Gobain Stadip Silence acoustic glass if high acoustic values are important. With acoustic values as high as 42 decibels, Zero|90 offers a unique proposition for commercial developers.
