At 1st Frame we supply uPVC sash windows which aim to replicate the aesthetic qualities of traditional timber sash windows, while overcoming many of the shortcomings that timber constructed windows create – especially regular maintenance & painting, and energy inefficiency.

A significant advantage of sash windows is that they provide efficient cooling of interiors during warm weather. Opening both the top and bottom of a sash window by equal amounts allows warm air at the top of the room to escape thus drawing relatively cool air from outside into the room through the bottom opening.
