In 2025, we’ve all pretty much heard of ‘spray foam’ insulation — it’s become more and more popular and is the solution many homeowners and commercial landlords are opting for. Simply put, it is an effective way to insulate a building with a foam that expands and hardens to fill gaps where more traditional forms of insulation would miss. We believe it is a solid choice when looking to make your home more energy-efficient, but there are a few things you should bear in mind.
Spray foam insulation is a liquid polyurethane foam, also known as Spray Polyurethane Foam (SPF), which is applied with a spray gun into areas such as roof spaces, walls, and floors. This can be particularly useful when it needs to be applied to tighter areas, causing minimal disruption.
Why choose spray foam insulation?
- Save on energy bills: Because spray foam expands to fill cracks and gaps, it creates a tight seal that stops warmth from escaping and can reduce your heating costs by up to 50%.
- A long-lasting solution: Experts say that spray foam can last for up to 80 years, meaning it’s not just a quick, short-term fix. When installed correctly (by a professional), it can keep your home energy-efficient for years to come.
- Perfect for hard-to-reach areas: The expandable nature of spray foam means it’s ideal for reaching even the most awkward areas and ensures you’re not missing any spots.
- Keeps out unwanted visitors: The foam can make it harder for pests (such as rats) to get inside your property, which can be especially handy if you live in a busy urban area or own a commercial premises.
But there are a few things to consider:
- Bigger initial outlay: Spray foam is more expensive than other solutions to install. So you might want to consider how long it’ll take to earn back the cost in energy savings.
- Requires professional installation: Spray foam isn’t a product you should try installing yourself. It requires special equipment, and the chemicals used during installation must be handled safely. If your spray foam insulation isn’t done properly, you could encounter problems down the line.
