1. A+ Energy Rated
Our uPVC windows are capable of achieving an energy rating of A+ with cost effective double glazing and with EnergyPlus a U-value as low as 0.8W/m2k with triple glazing.
Our Tilt & Turn windows are ideal to be used as fire exits or on high rise buildings. With a number of practical benefits, Tilt & Turn windows are available with as many options as our popular casement window.
Our patented bubble gaskets are welded to the frame as part of the manufacturing process, meaning a continuous seal all the way round, eliminating draughts and providing resistance to water.
4. Slim Sightlines
The ultra-slim sightlines designed into Liniar’s casement windows allow in maximum natural light – and result in more attractive uPVC windows.
Our uPVC windows are available in a number of colours, whether you want contemporary look or traditional we can help you decide which is best for your home.
6. Customised for You
There is a wide range of glazing and window configurations available for our Tilt and Turn windows, so they can be truly tailored to individual specifications.
We will be delighted to show the wide range of handles that can be used on our Tilt & Turn windows offering the best options to match any interior.
This style is an inward opening window that is hinged at the side and at the base. Turn the handle in a horizontal position and the window will tilt in at the top allowing for secure and efficient ventilation with the minimum of draught.
If you continue turning the handle into a vertical position, the window completely opens in allowing for the easy cleaning of both sides of the glass. The tilt & turn window is ideal for complying with the current fire regulations and is very adaptable to larger windows.
All windows are available in the standard colours- white, mahogany, golden oak, cream and bog oak ( black) as well as off standard colours. If you like the idea of a different colour on the inside of your home, we can offer combinations such as black on the outside and white on the interior.
The variety is endless .... but the quality is consistent.
