Moy Isover Plus Rolls
Moy Isover Sarking Batts are high quality lightweight insulating Batts, manufactured from mineral wool. This sarking batt has been developed specifically for use in ceilings following the pitch of the roof and enclosing a habitable space, thus servicing the market of attic conversions and new dormer bungalow construction.

If the sarking felt is not vapour permeable a minimum of 50mm airspace should be maintained between the insulation and the sarking felt. The structure should be lined on the room side with a vapour control membrane and Gyproc plasterboard. If the sarking felt is vapour permeable then the insulation can be fitted to the sarking felt.
Moy Isover Sarking Batts can be friction fitted between rafters prior to the fitting of the vapour control membrane. The use of a 175mm rafter is required to achieve a 50mm air space. If the specified rafter depth is not sufficient to provide this air space, the depth can be increased by adding timber battens to the inner face of the rafters.
Used in a typical roofspace, following the line of the roof but maintaining a standard 50mm of airspace on the cold side of the insulation, a U Value of 0.23 W/m²K will typically be achieved (this will vary with differing construction methods and should be calculated in each individual case).
Moy Isover Sarking Batts are non combustible to BS 476 Part 4.
Moy Isover Sarking Batts contain a water repellent silicone binder to ensure that no moisture will penetrate the batts.
Moy Isover Sarking Batts are rot-proof, odourless, non hygroscopic, do not sustain vermin and will not encourage the growth of fungi, mould, or bacteria.
