Energy Efficient 'A' Rated Windows

Liniar uPVC profiles deliver even more energy savings for the homeowner. See why Liniar's energy efficiency outperforms any other uPVC window profile system.

Energy Saving Trust Recommended

As an Energy Saving Trust certified manufacturer of uPVC windows, all of our Liniar products are Energy Saving Trust Recommended and therefore endorsed to use the "recommended" logo.

A+12 WER

The Liniar window system is capable of achieving a WER (Window Energy Rating) of A+12 using a double glazed sealed unit. We are not aware of another window profile system that can match this extraordinary level of energy efficiency.

Incredible U-values

The popularity of triple glazing is ever increasing creating new and profitable opportunities. With its new 36mm glazing bead, Liniar profile can achieve U-values as low as 1.0 W/(m²-K) with triple glazing.

100% Lead Free

Better for the environment, Liniar frames have always been made from completely lead free materials well in advance of legislation. Moreover, all elements of Liniar profile are 100% recyclable.

More Thermally Efficient

The revolutionary Liniar window system uses the very latest in uPVC profile technology. Its multiple size-optimised chambers are specially designed to lock in the heat and break up mini convection currents.

Revolutionary Thermal Dam

Designed specifically to meet PassivHaus recommendations, the Thermal Dam improves the level of thermal transfer which in turn helps to achieve exceptional U-values and Energy Ratings.

Superior Gaskets

Our patented double-action gaskets stop gaps from forming thereby preventing heat loss. Memory retentive properties maintain consistently tight weather seals throughout the product lifecycle.
