Why might you need spray foam insulation services?
Spray foam insulation is versatile and can be applied to walls, roofs, and floors. You might choose spray foam insulation if:
You want to lower energy bills by improving heat retention
You're tackling condensation or damp problems (when ventilation is managed correctly)
You're converting a loft and need insulation that fits into awkward spaces
You want a sound barrier between rooms or from outside noise
You're upgrading your property as part of an energy efficiency project alongside other measures
NB. Spray foam insulation should be installed by a certified installer to prevent issues with damp, mould, and poor air quality.

On Checkatrade, you'll only find trades who meet our high standards and pass up to 12 checks.
Types of spray foam insulation
Spray foam insulation is sometimes used in irregular or hard-to-reach places, and there are two main types:
Closed-cell spray foam: Denser and more rigid, offering a high level of insulation, although it is not vapour permeable. It can support the structure of the insulation area
Open-cell spray foam: Softer and more flexible, allowing more airflow. However, it's a less effective insulator (than closed-cell), so you'll need a thicker layer for the same effect
Some homeowners choose spray foam alongside other home insulation measures, such as solid wall insulation or cavity wall insulation, for a complete upgrade.
What to look for when hiring spray foam insulation services
Spray foam insulation isn't without its issues.
This expanding polyurethane foam has been used since the '70s, creating an airtight seal that can increase the structural integrity of the area it's used.
However, failure to install spray foam insulation correctly can lead to ventilation issues and damp. This is why it can be tricky to get a mortgage on a house with spray foam installation.
To help ensure you hire right, check for:
Relevant qualifications and accreditations
Membership of trade bodies, such as the National Insulation Association (NIA)
Proof of public liability insurance (and check it's up-to-date)
Warranties or guarantees offered on insulation work
Tip: When hiring a spray foam insulation installer, look for BBA, NAPIT, TRUSTMARK, KIWA BDA and NIA as markers of quality.

How much does spray foam insulation cost in the UK?
The cost of spray foam insulation installation will depend on the area size and accessibility, the type of insulation used, the preparatory work needed, and regional labour rates.

When it comes to spray foam insulation, quality is key. It's important to find a certified installer who offers a fair price but also has the necessary experience and expertise to get the job done right.
