AluK is relaunching its Luminia F82 bi-fold system aimed at customers who want to tap into the £250bn savings which the Bank of England estimates affluent households have accumulated during the various forms of lockdown.

Its sightlines measure a consistent 97mm all the way round the frame, cill and jamb and just 122mm at the interlock. 

There is also a distinctive pop-up T-handle on the traffic door. Available in white, black, anthracite, silver and brushed stainless-steel, this bespoke handle has been tested to 25,000 cycles, equivalent to around 80 years of regular use.

It has heavy duty 150kg capacity stainless steel compact rollers on the bottom. Weather performance is up to Class 4 air permeability and Class E900 water tightness.

The AluK F82 bi-fold has achieved PAS24 security accreditation, ensuring that it can be fitted in new build projects which require compliance with Approved Document Q. U-Value is1.34 W/m2K double glazed and 0.9 W/m2K triple glazed.

There are open-in and open-out, left and right options available for doors between two and seven panels in sizes up to 1200(w) x 2600(h), as well as corner posts to suit almost any configuration. There is also the flexibility to fabricate PAS24 accredited single and double doors using the same components to achieve a consistent overall look.

The F82 can be manufactured using just four key profiles and a reduced number of gaskets.

Marketing director Sioned Roberts says the F82 gives both fabricators and installers the opportunity to achieve strong and sustainable margins for themselves in a bi-fold market which has become increasingly commoditised over recent years. She added: “With the F82, we’ve used all of AluK’s vast experience and expertise in bi-folds to create a door which is quick and easy to manufacture and install yet can command a premium in a market where there has all too often been a race to the bottom on price. That’s a huge benefit for our customers.”
