Mammoth skillion sections are designed to promote high thermal performance in modern skillion roof or flat roof designs.
High density, moisture-resistant sections are made from 100% polyester with a controlled loft to ensure the required 25mm air ventilation gap to the roof is always maintained.
They are Red List Free and allow a smooth crease-free friction-fit to enhance thermal performance.
Mammoth Skillion comes in two thicknesses; 115mm (R2.9) or 165mm (R3.2) depending on the climate zone and how much room has been specified for the ceiling cavity.
* Calculations are based on 500ml PET Bottles (16.2g).
