Ultra-energy efficient aluminium windows with u-values as low as 0.89W/m2k
Aluminium lift and slide patio, French, entrance, and bi-folding doors. U-values as low as 0.68W/m2k
Highly flexible and fully integrated façade system for light commercial applications
Decalu radically simplifies aluminium window and door manufacture, reducing frame and sash components from eight in most aluminium systems to just three, reducing stock holding and delivering manufacturing efficiencies of up to 40%.
Decalu uses a co-extruded and pre-inserted gasket. This makes window and door glazing simple, using an easy-to-fit, pre-gasketed knock-in bead. And because it’s co-extruded with a rigid PVC backing, it won’t shrink – eliminating call backs for gasket shrinkage.
Decalu uses through-frame drainage across its complete range, leaving clean, contemporary and uninterrupted sightlines.
Decalu aluminium windows and doors are available in dual colour, marine grade and textured finishes as standard, making pricing simpler.
Decalu brings leading-edge thermal efficiency to aluminium window and door design, achieving u-values as low as 0.68W/m2k. With integrated thermal insulation, it can also accommodate IGUs of up to 71mm, making it Part L and Future Homes ready.
Fitted in under two-hours and glazed in less than four minutes*

When we developed Decalu we knew that we wanted to shake things up. We went back to the drawing-board and redesigned our entire range from the ground-up.
We asked fabricators, installers, homeowners and specifiers what they wanted – and we made it.
Decalu is an energy efficient, easy to fabricate and easy to install aluminium window and door system.
We want to give you the best possible service. Aluminium supply has been hit and miss – that is until now. We’re committing to changing the way supply works, with an industry leading OTIF and extensive customer support.
