All Seasons Foil™ Insulation

What Is All Seasons Foil Insulation?

All Seasons Foil is a premium multifoil insulation system fitted to your loft rafters or floor. Unlike traditional fibreglass, it works by reflecting radiant heat back into your home — keeping it warm in winter and cool in summer. It also creates an air gap and vapour barrier, preventing damp, condensation, and moisture damage in your roof space.

KMS Insulations are specialist installers of All Seasons Foil across the West Midlands and throughout the UK. Every installation is carried out by our qualified teams and backed by a 25-year manufacturer guarantee — giving you peace of mind that lasts decades.

"The most efficient loft insulation system available to UK homeowners today — and we install it properly, every time."

If you've been paying too much on your energy bills or noticing cold spots and damp in your home, a free thermal survey from KMS is the first step. We'll assess your loft, explain your options, and give you an honest recommendation — no obligation, no pressure.

Why Choose All Seasons Foil With KMS?

Because we don't just fit insulation — we fit it right. Our West Midlands-based team covers the whole of the UK, and every job includes a 2-month post-install quality inspection where one of our assessors returns to check your insulation is performing exactly as it should.

All Seasons Foil is BBA-accredited, mortgage-safe, and meets current UK building regulations. It's suitable for both rafter and floor installation, making it one of the most versatile and effective insulation options available to UK homeowners today.
