Perfect for installers
The launch of Alumina allows installers to offer a single source of supply and warranty
for a full house of fenestration products
Alumina by Liniar is a heavy-duty bi-folding door that’s strong, durable and resilient – as well as the most attractive on the market. Fully matching to Liniar’s PVCu windows, doors and conservatories, Alumina is the only aluminium bi-fold to enable you to offer customers a full product range with a single point of guarantee for their installation.
All Liniar bi-fold doors are bottom rolling, not top hung, so no extra forces are acting upon existing lintels – removing the need to add extra strengthening.
Alumina’s uniquely foiled aluminium bi-fold doors are supplied with matching PVCu beads, enabling faster glazing onsite and offer higher thermal efficiency for customers.
The optional low threshold and tray for Part M compliant threshold both require no trench excavation – making installation easier and faster.
If you don’t already offer aluminium bi-fold doors, Alumina will enable you to open up new markets in self-build or commercial projects where size is required but thermal efficiency is also key.
