Energy Efficiency

Energy Ratings

Energy efficient windows from Liniar contain a dual functionality that allows you to gain free solar energy from the world’s largest natural resource – the sun.

Tight weather seals are also an excellent feature as they prevent the worst of weather from entering your home. The gas contained within each window allows the free energy from the sun to heat your home, so there’s little need for central heating.

Each window comes fitted with a transparent metallic coating that reflects the heat back into the room. This is a great way of retaining heat and reducing the amount of energy needed to heat your home, which will ultimately save you money.

Recommended by the Energy Saving Trust

The Energy Saving Trust has certified the Double Glazing Network’s manufacturer of UPVC windows. Every Liniar product you have installed therefore comes fully endorsed with the Energy Saving Trust logo.
