The Liniar design team is constantly pushing the boundaries of product innovation, finding clever solutions to challenges that others have failed to address.
Continued investment in infrastructure, technology, machinery and a great team of people has helped Liniar to become one of the market leading PVCu window systems with a customer base of specialist fabricators all over the UK.
Liniar’s latest innovation, Alumina by Liniar, is a true aluminium bi-folding door system, beautifully sculptured and foiled to match perfectly with the full Liniar uPVC product suite.
Designed by experts
Alumina is more than just a bi-fold system. It can also be made into flush single aluminium doors or aluminium French doors as a perfect match to the Liniar uPVC Flush Sash window system. Designed by the same experts as innovative Liniar PVCu products, Alumina has a host of unique features and benefits.
Aluminium doors are not usually renowned for their high thermal efficiency, but Alumina has been designed with this in mind and can achieve U-values as low as 1.2 W/m²K. This is in part thanks to Alumina’s clever polyamide thermal locking system, providing a thermal break and preventing the transfer of heat outside the building.
As you’d expect from Liniar, the Alumina range achieves the highest levels of security. Its built-in hardware includes multiple bi-directional locking points, shootbolts, anti-lift features and anti-bump cylinders – ensuring all Alumina aluminium doors hold Secured by Design status.
Unlike most other aluminium doors, Alumina can be foiled with flat or woodgrain finishes. This means not only do the foils provide a ‘warm touch’ to the doors, they can match perfectly with foiled Liniar uPVC windows! Not only does this make for a seamless, attractive appearance, it means all the products in the installation are covered by a single point of guarantee (when fitted to Liniar’s guidelines).
True strength with size
If your door installation requires large expanses of glass, Alumina is ideal. Sashes spanning as high as 2.5m and as wide as 1.2m are possible and the product has been fully tested and passed at its maximum size, giving consumers peace of mind for durability and robustness.
