Watertight Expanding Foam: All You Need to Know

watertight expanding foam

Spray foam insulation is most commonly found in loft spaces, usually at joist or rafter level. This is one of the most effective methods of reducing heat loss through your roof.

It keeps warm air contained within the home during colder months, and helps to keep your property cool in the Summer.

The material is sprayed on as a semi-wet material and on contact the foam begins to expand. Once hardened, which takes a matter of minutes, the foam creates an all-encompassing blanket of effective insulation. But does spray foam insulation also seal out water? It's time to find out...

Does Spray Foam Insulation Seal Out Water?

Closed-cell spray foam insulation is completely resistant to water, and will repel liquids at all times.

Even if water is to get past your roofing system, spray foam seals any cracks or crevices in the wood deck, so the water will simply roll away with gravity, and off the edge of your property.

So does watertight expanding foam completely seal out water? In this case – absolutely!

Open-cell spray foam insulation does not have the same level of resistance to water absorption. However, once wet it does not stay wet.

This form of spray foam insulation will dry completely no matter how many times it becomes damp. The blanket’s shape may be affected if there is a substantial amount of water, but it will still dry out completely.

Can You Use Spray Foam Insulation on Damp Surfaces?

So what about applying this product on damp surfaces? Can spray foam insulation be used on surfaces that are expected to get wet?

Many people believe the material’s water resistance can trap particles of water, and cause the development of mould growth. This is simply not true. Spray foam insulation can be installed in various places where water is a particular consideration.

There is no evidence to suggest any possible damage or deterioration is caused as a result of using spray foam on damp surfaces.

Even if the application area gets wet quite often, the water-resistant nature of closed-cell spray foam in particular will ensure there are no issues.
