Therm A Glaze 30 is a 30 minute fire rated glazing seal for use in fire doors.

It has remained a popular choice for many joiner shops over the years due to its robustness despite its flexibility, which makes it easy to handle and very unlikely to break or become misshaped. The strips come in 2100mm lengths and are designed to fit either side of your pane of glass with a high tack self-adhesive backing to hold the strip in place.

This strip also benefits from being fully water stable, meaning that it is suitable for both external doors as well as in high humidity areas such as swimming pools and saunas, etc.
