What are the 3 fire resistance criteria for materials?
This material is classified into three categories: resistance mechanics or load-bearing force. tightness to flames and hot gases. thermal insulation.
What are the regulatory fire reaction classifications of construction products?
the ranking of reaction to fire in France
- M0: the product is non-combustible, so it does not power thefire.
- M1: the product is combustible but not flammable.
- M2: the product is hardly flammable.
- M3: the product is moderately flammable.
- M4: the product is easily flammable.
What insulation against fire?
The fire insulation reference are:
- calcium silicate panels (silico-limestone);
- concrete, in particular cellular concrete;
- clay brick, including monomur brick;
- the plaster ;
- ceramics;
- rock wool and glass wool;
- phenolic foam.
What are the reaction to fire criteria?
No particular reaction to fire requirement, but compliance with a “C + D” of 0.60 m to 1.30 m depending on the classification of the building and the mobilisable combustible mass of the façade (articles 11 to 14). For buildings subject to the Labor Code: No requirements on materials,…
How long do walls resist fire?
The most common wall and floor compositions (see examples in the next section) are more than 30 minutes fire resistant. In addition, building codes in effect for the past 30 years require separations with higher DRFs and therefore meet the minimum CBCS requirements.
What is the difference between reaction to fire and resistance to fire?
The reaction to fire is the representation of a material as food for fire (combustibility, flammability) The resistance to fire is the time during which the construction element plays its role of limiting the spread.
How to react to the fire of a facade?
No particular reaction to fire requirement, but compliance with a “C + D” of 0.60 m to 1.30 m depending on the classification of the building and the mobilisable combustible mass of the façade (articles 11 to 14).
