Alumina completes the fully matching range of thermally efficient fenestration products available from Liniar.
Starting from scratch with a slim, lead-free PVCu window system, the Liniar team has continued to design and develop new products. You can now choose a fully matching installation, with the highest quality products including:
-Sliding patio doors up to 4 panes wide
-Conservatory and lantern roofs
-Flush sash timber-replica windows
-French doors with or without sidelights
-Residential and composite doors
-Soffits, fascia boards and trims
-Decking and fencing
-Designed from scratch
The team recognised the need for a pure aluminium bi-fold that fully matched with Liniar uPVC windows so they designed one!
With 28mm double glazed and 36mm or 40mm triple glazed units available, Alumina offers ‘true’ U-values as low as 1.2W/m²K, thanks to its innovative thermal lock.
Liniar’s optional aluminium low threshold is just 23.5mm high at its highest point, requiring no trench excavation to install. Add a low threshold tray to make it Part M compliant.
-Foiled ‘warm touch’ exterior
Your Alumina bi-fold can be foiled with any woodgrain or coloured finish for a beautiful colour match to uPVC windows and doors.
Alumina ensures the highest security with multiple bi-directional locking points, shootbolts that secure firmly into the track, built-in anti-lift features and anti-bump cylinders.
-Attention to detail
With innovative features including folding keys, ergonomic handles, hidden fixings for hinges and discreet magnets, the attention to detail is what makes an Alumina bi-folding door ‘best in class’.
Alumina by Liniar offers a brand new concept in aluminium bi-folding doors.
Designed and developed by the same team of experts as the Liniar window system, the Alumina bi-fold door offers superb thermal performance and a host of other features to appeal to the discerning consumer.
Alumina by Liniar breaks new ground with superb strength, high security, low U-values, sculptured lines and a ‘warm touch’ exterior. With its launch, Liniar becomes the first window systems company to offer a full suite of fully matching products for any home.
For bi-folding doors up to 6.5 metres wide and 2.5 metres high, with high security locks, low U-values and a smooth glide, it has to be Alumina.
The Alumina bi-folding door range has a wide variety of options when it comes to sizes and opening configurations – available from 2 panes wide up to 7 panes.
Our door pane numbering works like this:
The first number shows the number of doors in total within the frame.
The second number shows the majority of doors folding back to either left or right.
The third number shows the balance of doors opening in the opposite direction.
So, a 4-3-1 bi-folding door would be four panes wide, with three doors folding back to one side of the frame, and a single opening door on the other.
