Innovative fabricator Whiteline’s latest product launch offers great business growth potential for PVCu installers. New Alumina from Liniar is a unique aluminium bi-folding door system, in fact the first true aluminium bi-folds specifically designed to match fully Sculptured PVCu window and door profiles, foils and finishes. So, for the first time installers can supply a complete and consistent suite of products to enhance any home or building and all covered by a single 10 Year guarantee.


Alumina’s aluminium construction delivers stronger, taller and wider bi-folds, with door sizes up to 1200mm wide and 2500mm high, ideal for larger applications where PVCu options just don’t go. Super energy efficiency, with U values as low as 1.2 W/m²K, and maximum security options (PAS 024, Document Q and Secured By Design) meeting the demands of the most discerning homeowner. Woodgrain foils or colour matching, a host of clever features and effortless operation are the final touches to seal the deal.

As ever, PVCu and Aluminium fabricator Whiteline is already in production and first to market yet again with Alumina, further improving their product range to customers and opening up even more selling opportunities.
