Sash windows need expert fitting; they don’t work very well if poorly installed. Unlike casement windows, there isn’t any coverage or overlap; air tightness comes from compression on the brush pile.
While there is no substitute for accurate fitting, we provide all sash windows with foam baffles – pads specially produced to reduce air infiltration.
Our MASTER INSTALLERS are a team of specially training craftsmen, chosen to deliver a quality installation of your Masterframe windows.
