Application

  • Pitched roof - between rafters.
  • Flat roofs - between the joist.

Consult manufacturer for installation details.

Description

ISOVER Metac is a glass mineral wool ‘slab on a roll’ insulation solution offering thermal and acoustic benefits for pitched roof between-rafter applications. It can also be used as the insulation between the joists in flat roofs.

Features and benefits:

  • Glass mineral wool roll (1200 mm wide) supplied in 50–200 mm thicknesses.
  • Manufactured from a minimum of 50% recycled glass.
  • Achieves an A+ generic rating within the BRE Global Green Guide.
  • Thermal conductivity of 0.034 W/m.K. Helps to reduce heat loss within the building envelope and decrease energy costs.
  • Weighted sound reduction of up to 49 dB (Rw)*, delivering excellent external noise reduction compared to other insulation materials. Helps to improve acoustic comfort of homeowners by reducing transmission of external noise from aircraft, trains, road traffic and weather.
  • Easy to install – robust ‘slab on a roll’ which is straightforward to handle, cut and install with minimal waste; any off-cuts can be reused. ISOVER Metac doesn’t ‘slump’ when installed and can easily be friction fitted between rafters without additional fixings.
  • Non-combustible - achieves a Euroclass A1 Reaction to Fire classification, according to BS EN 13501-1.

*Acoustic tests conducted by Salford University to BS EN ISO 10140-2:2010 for pitched roof rafter applications.

Application:

  • Pitched roof - between rafters.
  • Flat roofs - between the joist.
