ISOVER Metac
Metac is a robust ‘slab on a roll’ glass mineral wool insulation, which
can be considered for use between rafters in pitched roof applications.
It offers a 2-in-1 solution for its thermal performance and sound reduction
properties. The strong, resilient and flexible rolls are available in a range
of thicknesses to suit common rafter depths.
Metac can also be considered for thermal insulation between the joists in
flat roofing applications.

Product Benefits
- Thermal Performance - Thermal conductivity of 0.034 W/m.K. Helps to reduce heat loss within the building envelope and decrease energy costs.
- Acoustic Performance - When included within particular pitched roof rafter systems, Metac can help achieve a weighted sound reduction of up to 49 dB (RW), delivering excellent external noise reduction for those living or working within the building.*
- Sustainability - Manufactured from a minimum of 50% recycled glass. For further details visit insulation-uk.com/CSR
- Easy to Install - Metac friction-fits between rafters without slumping, or the need for any additional fixing. The roll width allows cutting to different rafter centres, providing maximum flexibility and efficiency on site, with minimal waste (off-cuts can be reused).
- Fire Classification - Achieves a Euroclass A1 Reaction to Fire classification, according to EN 13501-1
