Mammoth Skillion Roof Insulation

A stiff, high-density polyester insulation designed for flat roofs or confined ceiling spaces.

Mammoth Skillion Roof InsulationMammoth™ Skillion high-density polyester is designed specifically for the current New Zealand 'flat roof' trend, first used in kiwi holiday homes and now seen in many mainstream new houses.

Mammoth Skillion doesn't "loft" or increase in volume over time, ensuring the required 25mm air ventilation gap to the roof is always maintained. The product is stiff - making it very easy to handle - and cuts easily with a Bahco Insulation Saw (available from major hardware merchants).

No precautions are required for handling Mammoth products; they will not cause irritation when touched or give off any fumes or odours.

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. For full technical details download the datasheet at the bottom of this page.
