GreenStuf® Thermal Ceiling Insulation
Thermal insulation available in pads and blankets.
This product was known as Skillion Roof but was recently changed to GreenStuf® Thermal Ceiling Insulation.
To reduce heat loss in your home, the ceiling is the most important place to insulate. GreenStuf Thermal Ceiling Insulation is available in pads ideal for placing between joists/trusses, and roll form ideal for rolling out between joists or trusses and as a blanket.
Double layer system
GreenStuf insulation will not settle or reduce its performance over time. In fact, we are the first BRANZ appraised double layer insulation system. Our double layer system (R6.8) will help you achieve R6.6 construction R-value for H1 compliance in residential ceilings.
