Underfloor Insulation: The Smart Option

Our Enviro Blanket® Underfloor is 100% polyester blanket underfloor insulation designed for flexibility. It’s perfect for use between variable joist spacing, which is common in older New Zealand homes.

Underfloor

Better than polystyrene insulation.

With Harrisons’ own exclusive Enviro Blanket®, there’s no need for cutting or trimming to fit. That means no mess and a greatly reduced installation time.

Our underfloor insulation is simply stapled into place between the joists without the need for clips or tape, it will significantly reduce heat loss and drafts caused by joins in the floor. You’ll have warmer feet and a warmer home!

Underfloor insulation for warm feet and lower energy bills

Enviro Blanket® Underfloor is 100% polyester blanket insulation designed for easy installation. It’s backed by a 70-year product warranty and 10-year installation guarantee (Terms and conditions apply)
