BRINGING THE OUTSIDE IN

Bi-fold doors are the perfect way for you to create space, let in fresh air and flood your home with natural daylight by being able to open up an entire wall of your home. Whatever purpose you have for your bi-fold doors, the Liniar product provides a truly stunning alternative to French or patio doors.

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 leading brands in the UK. A door’s thermal efficiency is measured 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, resulting in reduced energy costs.

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. To see how to operate these unique bi-fold doors, search “Liniar’s Bi Fold Operation Guide” on YouTube.

ULTRA-SLIM SIGHTLINES

Liniar bi-fold doors have ultra-slim sightlines, providing rooms with a modern, clean appearance – and are available in a wide choice of opening configurations and colours. The innovative low threshold option is just one of the safety features included, making them family and wheelchair friendly. Find out about the range of thresholds available from your sales representative.
