SKILLION SECTIONS

High performance skillion ceiling insulation sections for new homes without a roof space.



Description

Mammoth skillion sections are designed to promote high thermal performance in modern skillion roof or flat roof designs.

Mammoth® 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.

Mammoth products contain recycled polyester fibres. Mammoth ceiling skillion section insulation uses up to 9,300 recycled PET plastic bottles per 100sqm*.

They are Red List Free and allow a smooth crease-free friction-fit to enhance thermal performance.

For ceilings with sufficient roof space there is the option of our Ceiling Blanket Insulation and for skillion and truss roofs we have Ceiling Batten Insulation.

Q&A/FREQUENTLY ASKED QUESTIONS



A Skillion Roof is a roof that tends to have one sloping surface in contrast to a gable or hip roof that tends to have two or more sloping surfaces meeting near the middle.

Modern architectural homes use a variety of roof designs and Mammoth Skillion Sections can be used in any roof design where the ceiling runs roughly in parallel to the roof line.

It is essential that Skillion Insulation has a controlled loft so that it does not encroach into the required air space between the insulation and the roof lining.

Retrofitting insulation into a skillion roof has some challenges and it depends on the type of skillion roof you have.

Exposed Rafters: You can fit insulation into the gap between the rafters and then line the ceiling with wall-board attached to the rafters.

Hidden Rafters: Adding insulation is only possible by either removing the roofing to fit from above or removing the ceiling lining to fit from below. Adding or upgrading insulation would be best combined as part of a re-roofing or renovation/redecoration project.
