Ideal ratio between mechanical properties and fire resistence

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 C boards

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 C

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