Installation Pitched Roof
✔✔ Measure depth and width of rafters. Then measure the length and width of
the building and multiply twice the span of the rafters by the length of the
building.
✔✔ Lift Metac into the attic still in its packaging.
✔✔ Measure and cut the roll to fit rafter width leaving 10mm extra on dimension.
✔✔ Unroll and allow full recovery, use a straight edge and sharp insulation knife.
✔✔ Push and friction fit between rafters, keeping flush with rafters. Ensure eaves
ventilation is left where required.
✔✔ Metac can be fully filled* between rafters when used with our Vario XtraSafe
membrane installed below the insulation with Gyproc Plasterboard to
complete the installation - this provides the safest solution to protect timber
rafters from moisture damage.
✔✔ To increase the u Value Isover recommends installing 50 x 50mm counter
battens filled with 50mm Metac – this allows a service zone without need to
pierce airtight membrane.
✔✔ Finally use Gyproc plasterboard applied to counter battens to complete the
installation.
