Aluminium Sub Frames
The foundation of a perfect aluminium installation. Our sub frames ensure precision, strength, and a lasting fit.
What Is a Sub Frame?
An aluminium sub frame is a structural bracket installed into the wall opening before the window or door frame is fitted. It creates a precise, level mounting surface that compensates for any irregularities in the brickwork.
Sub frames are essential for achieving a clean, professional finish. They distribute the load of the frame evenly, preventing wall cracking and ensuring your aluminium installations perform perfectly for years to come.
