Importance of Correctly Installing Spray Foam

Did you know it is not enough to equip your property with spray foam insulation but you also have to install it correctly?

The correct way to install spray foam is through professionals when they follow manufacturers guidelines.

That’s how you ensure that you get the benefits offered. Incorrect installation can mean zero benefits leading to different issues and safety concerns as well.

What could these issues look like?

Reduced airflow: the air circulation in the roof space can seriously go down because of improper installation.

Dampness and condensation: poor airflow may invite dampness and condensation, which can damage the roof structure.

Structural delay: you may start noticing decay in timber roof beams and other structural components.

Costly removal: if it is improperly installed, spray foam will need expensive removal and reinstallation, and this can be very expensive.

The right way to circumvent these issues is to use a reputable company for spray foam installation.

Recommendations for Homeowners

Homeowners should maintain thorough records of the spray foam installation, including:

– Keep all spray foam guarantees.

– Get independent validation certificates from organizations like KIWA and BBA.

– Document any survey conducted before the installation.

These records can be very important whenever you’re selling or refinancing your property.

Mortgage Considerations

Spray foam insulation, particularly in timber-framed roofs, can affect the ability to get loans – the insulation type and installation quality are aspects largely responsible for that.

Lenders generally ask for a professional survey to check out the insulation before approving loans.

Addressing installation issues

Homeowners should be careful of companies that pose as surveyors who falsely claim non-compliance with spray foam installations, recommending unnecessary removal.

Isothane advises against removing correctly installed spray foam and works to report fraudulent companies to Trading Standards.

If you are approached by such companies, you should first consult with the original installer. Those who installed spray foam insulation under the Green Homes Grant and feel misled can ask for compensation under the Consumer Protection from Unfair Trading Regulations 2008.

For disputes with traders, legal advice and assistance from Citizens Advice are suggested.

Expert Advice

The Home Owners Alliance (HOA) suggests that surveyors inspect the roof’s exterior since the internal structure is covered by spray foam.

In March 2023, the Property Care Association (PCA) released a spray foam inspection protocol to help surveyors identify risks within pitched roofs.

The PCA provides training programs that equip surveyors with the skills needed to assess spray foam applications and propose solutions when problems come up.

Sticking to Standards

The National Insulation Association (NIA) emphasizes that spray foam insulation design and installation should comply with the latest building codes and regulations. Homeowners should hire only licensed and certified contractors who are skilled in using spray foam. This will avoid future issues.

Isothane also advises homeowners to research and choose experienced, licensed spray foam installers. With proper installation, you can be sure that the insulation adds value to the property rather than detract from it.

So we can conclude that if you want effectiveness and safety for your home as far as spray foam insulation is concerned, you will need proper installation by professionals who are verified and certified.

One way to do that is to hire reputable and licensed professionals and keep detailed records of the installation – this way, you can avoid any unforeseen issues that would be costly to fix and make sure that the insulation actually adds to the value of your property.
