Draught Proofing solutions for sash windows
3mm may not sound a lot but it is all it takes to create so many issues with older windows. This tiny gap is the key to smooth movement in a window, yet is large enough to cause draughts, rattles, water ingress, dust build up and reduced energy efficiency.
Our Perimeter Sealing System closes the gap without altering the outward appearance of the windows, it’s a hidden solution to the hidden problems you can’t usually solve on your own.
