Q GreenStuf UNDERFLOOR GreenStuf® Underfloor is 100% polyester thermal insulation rolls, precut to fit exposed timber joists. APPLICATIONS GreenStuf Underfloor is designed for use in residential and commercial exposed joist floors. GreenStuf Underfloor is available in a range of widths and performance options and can be installed in new and existing buildings with enclosed and semi-enclosed floor spaces. In open sub-floor spaces, it is recommended that a suitable lining material is applied. In addition to the above recommendation, where wind wash is a concern we suggest selecting the highest R-value GreenStuf Underfloor suitable for the building to maintain maximum thermal performance of the floor system.
