Explaining Energy Efficiency

The installation of energy efficient windows, doors and roofs is one of the best ways you can save energy within your home.

Mainly due to our innovative uPVC multi-chambered profile design, Liniar frames outperform most of the other leadings brands in the UK.

A door’s thermal efficiency is measure in U-values. These demonstrate the effectiveness of a door at stopping the movement of heat into and out of a property.

The lower the U-value is, the higher the door’s efficiency at preserving the heat inside of a building when cold outside.

The Liniar bi-fold range can achieve a U-value of 1.3 W/m²K when fitted with cost effective double-glazing units, which means you’ll be able to enjoy a warmer and quieter home as well as lower energy bills.

Innovative

Slim hinges have been added, with hidden fixings inside. This not only seamlessly preserves the sleek lines but increases security as it is impossible for them to be unscrewed externally.

We designed our own innovative solution to enable us to offer a low threshold without the need for expensive and messy excavation.

It’s often the little things that make a big difference – we’ve even designed folding keys to avoid any problems with keys being left in the locks during use.
