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



 
Properties and applications of Grenamat B, C boards

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.
