    How is Supafil CarbonPlus Installed?
    supa-icon The insulation is blown into the floor cavity space by Approved Installers. Prior to installing the insulation, a material veil (BIB) is attached to the underside of the floor framing. The newly formed cavity is then completely filled with Supafil CarbonPlus. The insulation will fill all gaps and voids and around pipework to ensure complete, even coverage. After installing the insulation an appropriate lining is applied. The process is quick and clean and complements the construction process. 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.
