Liniar’s design & fabrication director, Daryl Fradley, explains how the Alumina system makes achieving consistent results much easier when working with aluminium and PVC-U side by side.
Incorporating products made using different materials into a wider project whilst ensuring consistency in style and colour can be tricky. At Liniar, we took this into account when developing our aluminium door system – Alumina.
The range includes bi-folding, French and residential doors, and is the UK’s only flush sash, sculptured bead aluminium door range that’s perfectly colour matched to an industry-leading PVC-U window and door suite.
Consistent Aesthetic
Alumina is ideal for larger openings due to its strength and can handle sashes up to 1.2m wide by 2.5m high, with door sets up to 8.5m wide available for supply in flat pack format.
Many customers are looking to open up entire walls with either bi-folding or French doors and need a solution that fully complements the project’s other windows, doors and roofline regardless of their material.
Because Liniar foils the aluminium profile used for Alumina at the same state-of-the-art lamination facility as our complete range of PVC-U windows, doors and roofs, you get a perfect colour-match.
There are many woodgrain options available, so Alumina can complement traditional timber too. And Alumina doors offer a sleek, flush finish, making it perfect to complement our PVC-U flush sash window ranges, including our hugely popular Resurgence.
When combined, a similar look to traditional timber can be achieved, but with all the low-maintenance and thermal benefits of the Liniar range.
What’s more, we can deliver bespoke colour combinations across Liniar’s Alumina and PVC-U ranges, allowing installers to offer customers highly personalised products.
Foiled aluminium also provides a ‘warm touch’ finish which drastically reduces the cold, metallic feeling users often find off-putting about aluminium doors. And whilst foiled aluminium does present various advantages, Alumina is also available in plain white, black and grey powder coated finishes.
Besides the colour-matched options, all the detail on Alumina is exactly the same as Liniar’s PVC-U sculptured windows and door system too, so a building fully fitted with Liniar windows could have matching large-scale aluminium doors.
Easy ordering, efficient glazing
Alumina can either be supplied in bar length profiles, or ready-made kits comprising the full door minus glass, ready to go straight into the aperture.
We provide the glazing unit sizes, and installers can then use their local supplier. There’s a flexible bead option available, which requires no wedge gasket and takes a third of the time to fit compared with traditional aluminium beads.
All this simplifies ordering, reduces labour costs and makes for quick convenient installation with minimal disruption to homeowners.
Concealed ventilation & enhanced security
Changes to Part F of the Building Regulations came into effect in mid-2022 making the provision of adequate ventilation stricter and, in many cases, forcing the use of unsightly trickle vents on windows and doors.
With the Alumina system, externally concealed ventilation can be accomplished using an innovative 40mm add-on. This makes compliance with Building Regulations easily achievable, without spoiling the doors’ sleek appearance with trickle vents visible from the outside.
Alumina also offers enhanced security and is tested to PAS24 standards and is Secured by Design approved. What’s more, the Alumina bi-fold has been tested to more than twice the industry requirements for both air and water tightness – even with a low threshold.
Liniar has designed and developed an extremely attractive, versatile aluminium system that is well suited to both residential and commercial projects. As part of the team responsible for fabricating Alumina kits, I can honestly say we take great pride in ensuring every door leaving the factory is finished to exacting standards.
