Insulating your home is generally a good way to cut back on energy bills and add value to your property. 

But there’s one type of insulation to be wary of: spray polyurethane foam (SPF).

It’s sprayed in liquid form into roofs, where it expands, sets and then acts as an insulator.

What’s the problem?

SPF can block airflow and cause condensation. Over time, this can lead to wooden beams and rafters rotting. 

And because spray foam sets hard across the inside of the roof, it’s impossible to inspect what’s going on underneath. For this reason, many surveyors won’t sign off on properties with spray foam.

Implications

Many banks won’t lend on homes with spray foam, so its presence can impact a property’s saleability. Equity release products may also be out of the question.

What if spray foam is in your property?

Speak to a surveyor.If they recommend removal, get a specialist in to do the job (check their credentials carefully).

Costs may vary, but expect the bill to run into the thousands.
