FAQs

While glazing gaskets primarily seal the perimeter edges of glass panels, glazing liners provide fire protection across the entire glazed area. Liners are typically sheet materials or strips that cover or line the glazing rebate, whereas gaskets are sealing components around the glass edges.

When exposed to fire temperatures intumescent glazing liners expand to fill the glazed opening. This creates a fire rated barrier that prevents fire and smoke from spreading even if the glass has failed due to flame exposure.

When exposed to extreme heat, the intumescent material expands significantly (up to 10-20 times its original thickness), forming a char that seals the opening. This creates an effective barrier against fire, smoke, and hot gases without requiring any mechanical activation.

When exposed to fire the intumescent material in the strips activate that causes them to expand to 10 times their original thickness. This expansion fills gaps, cracks and prevents flames and hot gases from passing through and spreading.

Fire rated glazing tape is faster to apply, and provides instant adhesion without curing time. Sealants can be messier but may be more flexible in irregular joints. It depends on your requirements and the structural design.

The foam expands upon application when it is applied to gaps around fire doors and window frames. When exposed to high temperatures fire expanding foams a re designed to expand even further providing a thick layer of protection for fire doors, door frames and window frames.
