Grenamat B, C – Ideal ratio between mechanical properties and fire resistence

Grenamat B and Grenamat C boards are made of expanded vermiculite with wood and organic binders

Its mechanical properties are close to the chipboard, but it maintains its high fire resistance

GRM Australia Grenamat B, C

Properties and applications of Grenamat B, C boards

Grenamat B boards belong to fire reaction class B – s1, d0 and are used as a fire door panel with fire resistance of 15 – 45 minutes. Depending on the fire reaction requirement, they are also suitable as interior and acoustic tiles.

Grenamat C boards belong to fire reaction class C – s1, d0. They can be used especially in constructions of DP / 3 type such as fire-protection doors, fire-resistant door frame lining and similar constructions.

Machining and processing Grenamat B, C

Grenamat B, C vermiculite boards are easily machined with conventional woodworking tools. When working with them, there is minimal dust.
