KENMERKEN & VOORDELEN

Therm-A-Foam is a preformed linear joint seal comprising one or more layers of 10mm or 20mm flame retardant polyurethane foam coated on both sides with Therm-A-Flex intumescent material.

These layers are combined to produce a product suitable for sealing a range of gaps sizes in building structures.

The flexible open cell foam structure allows Therm-A-Foam to compress by approximately 50%, thereby enabling it to take the
shape of the building joint it is protecting.

At approximately 180°C the installed Therm-A-Flex begins to expand. During this expansion the flame retardant foam degrades and is replaced by the expanding intumescent graphite thus providing fire protection to the building joint.
