Chamfered Putty Line Sashes

We know you’ll care as much about the authentic details of your windows as we do. Externally, old wooden sash windows had putty glazing which sloped back to the glass at an angle of 45 degrees. This lovely ‘putty-line’ is included on every Masterframe window for this very reason. Internally, our beads are by contrast Ovolo shaped, just like on original Victorian and Georgian sash windows.

Our sash profiles are all multi-chambered. This means there are three individual pockets inside the PVC-U sections so that the galvanised steel reinforcement is inserted into its own sealed chamber. This is located well away from the separate drainage channel that allows rainwater to run away easily.

Whilst Classic Collection sash windows have the standard beads and glazing bars, both Harmony and Symphony have the larger more traditionally detailed versions and as a result can accommodate slimmer, Krypton gas filled glass units.
