What is B1 material?

European Flame Retardant Standards M1 B1 is the European flame retardant standard for contract drapery. It is used across Europe so companies are aware that a fabric and in turn the curtain made from that fabric is flame retardant and can be used safely in a commercial environment.

What is B2 foam?

B2 rated polyurethane foam filler. The cured foam is a good temperature and sound insulator, and has strong adhesive properties. Used for installation of doors and windows, insulation and fixing of pipework, filling gaps and holes, fixing wall panels and roof tiles and for thermal insulation.

What is B3 foam?

FM365 is a rapid curing, high yield, one component gun grade expanding polyurethane foam that is suitable for general gap filling, bonding and insulation applications.

What foam is fire resistant?

Silicone foam is flame-retardant, self-extinguishing & can withstand 2100 degrees F flame for more than 10 minutes without burning. Silicone foam is non-corrosive for use with metals & in hostile environment.

What is fire class B1?

The valid norm is differentiated into two fire protection classes. ‘A’ stands for non-flammable and ‘B’ for flammable materials. Class B is relevant for PU foam. This is then subdivided into the following levels: B1 = low flammability.

What is B1 foam?

B1 FOAM meets the fire resistance class B1, which is the best fire resistance classification that can be obtained for a PU-foam. B1 FOAM has a high insulating value, thermic as well as acoustic, and meets all noise standards to 57 db. B1 FOAM has an excellent adhesive power to most materials.

What is B1 expanding foam?

Everbuild B1 Fire Resistant Expanding PU Foam is a modified one component polyurethane foam for the filling / sealing of joints and gaps requiring fire resistant properties. The foam expands rapidly after dispensing and quickly cures to a fine honeycomb structured foam by reacting with atmospheric moisture.

Is all foam fire retardant?

All the foams we supply are UK manufactured fire retardant grades that fully comply with UK Fire Safety Regulations.

Is polyurethane foam fire resistant?

Pure polyurethanes are flammable and can ignite easily. However, it is common to add fire retardant chemicals to polyurethane that reduce its flammability to some extent.

What is B1 and B2 fire rating?

This is then subdivided into the following levels: B1 = low flammability. B2 = normal flammability. B3 = high flammability.

What’s the difference between B1 and B2 fire foam?

This is then subdivided into the following levels: B1 = low flammability. B2 = normal flammability.
