GreenStuf Underfloor is specially designed to provide effective thermal insulation for exposed joist floors in both new and existing timber-framed homes. It helps to minimize heat loss through the floor and reduces drafts caused by gaps in the floorboards, creating a more comfortable and energy-efficient living environment.

Available in a variety of thermal performance options, GreenStuf Underfloor comes in pre-cut rolls that are designed to fit standard exposed timber joist floors for easy installation.

Ideal for retrofitting older homes, GreenStuf Underfloor can be quickly installed by stapling it between the joists. Made from soft, durable polyester, it is itch-free, non-irritating, and perfect for DIY projects, helping you enhance your home's warmth and comfort while promoting the health of your family.
