# Putty glazing

Putty glazing

Putty glazing is the traditional method of securing glass panes into timber window frames using linseed oil-based putty (often called glazing compound).

The sealing process of the glass pane involves pressing putty around its edges which creates a weather-resistant barrier that permits wood movement and air exchange to safeguard historic timber.

The authentic appearance and lasting performance of putty glazing makes it the best option for heritage sash window restoration because it differs from modern silicone and dry-glazing systems.
