First off, we are going to talk about Expanding Foam, it's uses, and it's specifications.

The Dictionary definition of Expanding Foam is as follows:

A Solid or spongy cellular material produced by the reaction of a polyester (such as glycerin) with a disocynate (Such as toluene disocynate) while carbon dioxide is liberated by the reaction of carboxyl with the isocynate; used for the thermal insulation, soundproofing and padding.

Expanding Foam has many names, some of which include: Builders Foam, PU Foam, Squirty Foam, Polyurethane Foam and many others.

The main use of Expanding Foam is Gap Filling!

For many industries Expanding Foam is a real problem solver. The main industry and, in our experience the biggest user of Expanding Foam is the window industry. In the installation of windows and doors PU Foam is used for sealing the surround of the window or door into the surrounding substrate, usually the wall. The benefits of using Expanding Foam is that it cures or "goes off" quickly, it cures hard and after curing can be cut, painted and sanded.

Fire Resistance.

Expanding Foam comes in 3 levels of fire resistance. B3, B2 and B1.

B3 is the lowest level of fire resistance, conforming to (DIN 4102 Part 2)

B2 is the second level of fire resistance, conforming to (DIN 4102 Part 2)

B1 is the highest level of fire resistance, conforming to (BS 476: Part 20)

The fire resistance is dependent on joint configurations and testing procedures.

The Expanding Foam we sell at UKsealants is manufactured by Tremco Illbruck, part of one of the world's largest sealant and foam manufacturers.

We sell the B3 and the B1 versions of their Expanding Foams. the reason we have not chosen to sell a B2 version is that we can offer the B1 Grade at such a sensible price it negates the inclusion of a B2 rated product.
