Expanding foam is an excellent tool for every builder to utilise when attempting to seal cracks, fit windows and fill holes around a building.

This foam is incredibly versatile and can come in all shapes and sizes but is usually found as a handheld can or a gun-grade version. Here at Fastbuild, we offer a range of expanding foams for construction, but in this article, we will be highlighting the Soudal Standard E3 Expanding Foam.

What is Soudal Standard B3 Expanding Foam?

The Soudal Standard B3 Expanding Filler Foam is a multifunctional product made of polyurethane. This incredible substance can adhere to most common building materials and is even resistant to heat, water and ageing.

You can apply this particular foam via handheld or an expanding foam gun, with the size (750ml) remaining the same across both application types.

The Benefits of Standard B3 Expanding Foam

Now, let's touch on the many benefits and perks that the Standard B3 Expanding Foam can bring to your arsenal.

Prevents Moisture

Durable

Lastly, this foam is guaranteed to retain shape, effectiveness and positioning for decades. No matter the terrain or weather intrusion, you can be confident that the product’s high R-value will keep it locked down. Additionally, its ability to last also means that it is an environmentally-conscious tool.
