You need a product that’s easy-to-install and does a top job keeping your home warm and dry. At EXPOL, we offer two grades of easy-to-install underfloor insulation for timber floors – and both exceed the Residential Tenancies Act requirements.

EXPOL R1.4 UnderFloor Insulation – a great choice for keeping your home warm

R1.4 is suitable for new and existing homes… and yes, it’s quick and easy to install! It fits snugly between timber floor joists and stops drafts and damp from entering. It’s also long-lasting – which means your home will be warm and dry for years to come. When you choose R1.4 you also get insulation with a BRANZ-appraised 50-year limited product warranty.

EXPOL R1.8 Black UnderFloor Insulation – the choice for houses in extreme conditions

If your home is subject to extreme conditions – or if you just want the ultimate level of insulation – EXPOL R1.8 Black UnderFloor Insulation could be the best choice for you. It is 30% more efficient and is ideal for cold or windy underfloor environments.

Easy installation

The best news? Both have been designed for easy DIY installation. EXPOL UnderFloor Insulation panels are concertina-cut on both sides to allow for a compression of up to 20mm. This makes installation easier and also ensures a snug fit between joists.
