Energy Efficiency

Each of our double glazed products are highly energy efficient and are designed to keep your home warmer for longer by locking in the heat from your central heating. This is also an excellent way of saving you money on your heating costs as you will notice how little you need to turn your heating on after your new uPVC windows have been installed.

Liniar’s uPVC profile is cleverly fabricated in order to gain free solar energy from the world’s largest natural resource – the sun. With tight weather seals in place, all draughts and cold spots are eliminated so you can enjoy your warmer living environment.

The glass within each of our uPVC Liniar windows comes fully fitted with a transparent metallic coating which reflects the heat produced by the sun back into the house. Your windows will retain the warmth and reduce the amount of energy that is needed to heat your home.
