Is Spray Foam Insulation Actually Worth It?

Spray foam insulation explained for UK homeowners. This guide covers spray foam insulation in lofts, including open cell vs closed cell, moisture risks, roof damage, and why mortgage lenders sometimes refuse homes with spray foam. 🔑 Key Takeaways • Professionally applied spray foam is not the same as the DIY stuff from a can • Open cell and closed cell foams behave very differently — the wrong choice for your roof type can cause serious moisture problems • Surveyors can't see behind foam without an invasive inspection, which is why mortgage lenders get nervous • Ventilation is non-negotiable — spray foam alone is never the complete solution • If you have it done, get the guarantee underwritten by an insurance company, not just the installer • DIY spray foam kits are high risk unless you really know what you're doing • If you're planning to sell, think very carefully before going ahead 📋 Before You Commit Get your roof properly surveyed, document everything, and make sure you understand what membrane — if any — is currently in your roof space. The foam itself isn't the enemy. Poor installation and the wrong product for the wrong roof is. 📬 Got experience with spray foam?
