Why choose a Liniar door?

Energy bills are on the increase, environmental concerns are higher on the agenda than ever before and building regulations are becoming more demanding every year. Choosing doors that offer better U-values for a lower cost therefore makes good sense.

With Liniar’s lead-free, multi-chambered profile, patented co-extruded bubble gasket and other energy saving design features, you don’t need expensive triple glazing to achieve the highest energy ratings – Liniar doors achieve excellent thermal efficiency with cost effective double glazing.

The uPVC profile, or frame, in a Liniar door contains multiple chambers to minimise the transfer of heat from the inside of your property to the outside. This, together with other innovative design enhancements, helps to minimise energy costs on an ongoing basis.

Liniar’s ModLok™ patio door and standard bi-fold range can achieve a U-value of 1.3 W/m²K when fitted with cost effective double-glazed units. And for even greater thermal efficiency, Liniar’s ModLok™ bi-folding range can be fitted with triple glazing, reaching an impressive U-value of 1.0 W/m²K.

Most uPVC systems haven’t fundamentally changed since they were first launched in the 1980s – and with uPVC traditionally requiring steel reinforcement inside the frames, energy efficiency usually had to take a back seat.  But not with the Liniar 70mm system – it was designed from scratch using the very latest technology to meet the demands of today’s house building market…. resulting in products that are not only strong and secure but that also achieve one of the highest energy ratings – in one system.

The Liniar design team continues to push the boundaries, creating new products and enhancements to ensure the range is the most innovative and sought-after on the market.

Continued investment in design facilities, tooling and machinery ensures the very latest techniques are used to create each component within the Liniar system. This includes the latest 3D printer to generate working models of the components to allow testing; high-tech tooling and machinery to facilitate extrusion in the most efficient way possible, and the addition of an articulated cyclic testing robot to put Liniar products through their paces.

The full Liniar range has been designed to save time for installers, making it ideal for large scale new build projects where speed is of the essence. Bespoke glazing platforms mean double or triple glazed units are fitted into the frame more effectively, and Liniar’s unique beading system provides a quick, easy and attractive finish.

The Liniar patio can be mechanically jointed, making it easier to install in hard-to-reach areas – and the low threshold option on both the patio and bi-fold systems doesn’t require trench excavation, reducing preparation time for fitters.

Liniar’s co-extruded gaskets ensure no draughts or leaks for the end user – resulting in fewer call-backs and happier customers for installers.

There’s even a library of videos available for installers to show them exactly how to fit Liniar products to the highest quality standards, paired with installation guides to refer to on site, both of which are accessible from this website.

Furthermore, all Liniar profiles are guaranteed for 10 years against discolouration, splitting, warping or cracking – so they stay looking beautiful for longer.
