Skillion Roof Application


Supafil CarbonPlus is a high performance acoustic solution for skillion roofs in existing homes. It fills the cavity, maximising the potential acoustic performance. Unlike other solutions that require the existing lining to be removed, Supafil CarbonPlus can be installed through small holes made in the existing internal lining. Supafil CarbonPlus should only be installed by Approved Installers to ensure the highest quality and installed performance.

How is Supafil CarbonPlus Installed?
The insulation is blown into the roof cavity space by Approved Installers. Supafil CarbonPlus is installed through an existing lining or a material veil (BIB) is attached to the underside of the roof framing. The newly formed or existing cavity is then completely filled with Supafil CarbonPlus. The insulation will fill all gaps and voids to ensure complete, even coverage. After installing the insulation an appropriate lining is applied. The process is quick and clean and will provide minimal disruption – it will be completed before you know it. The installation of insulation will only be carried out once a full assessment of the suitability of the property and area to be insulated has been completed.
