Metac is a glass mineral wool ‘slab on a roll’ insulation for pitched roof rafter applications which delivers a range of benefits for the housebuilder, installer and home owner. As well as excellent thermal performance, Metac provides a proven acoustic benefit by helping reduce external noise from traffic, trains, planes and weather by 49dB (RW). It also offers a more cost effective and easy to install solution than many alternative insulation materials.
Metac is listed on the LABC Registered Details scheme for use in pitched roof rafter applications. See Certificate No.EW1027D for more information.

Key Benefits
Thermal Performance
Metac has a thermal conductivity of 0.034 W/mK. It can be installed in a range of pitched roof rafter systems to meet and exceed Building Regulations.Acoustic Performance
Many homeowners living in loft spaces are affected by external noise such as aircraft, trains, road traffic and weather. Unlike many other insulating materials, Metac’s sound absorbing properties enhance acoustic comfort by helping to reduce this external noise. Independent testing has shown that when installed into a pitched roof at rafter level, Metac can provide a weighted sound reduction of 49 dB (Rw)*.*March 2018 - University of Salford Acoustic testing to BS EN ISO 10140-2:2010.
Cost Effectiveness

Accurately fitting some alternative rigid board materials between rafters can be difficult. This can lead to increase installation time and air gaps that can compromise the thermal & acoustic performance of the roof. Metac is quick and easy to handle and cut. It doesn’t ‘slump’ when installed & can be easily friction fitted between rafters, minimising air gaps.Low Waste Solution
Installation of some alternative rigid board materials can lead to large amounts of off cuts and waste. Metac generates minimal waste during installation and any offcuts can be re-used within tighter rafter spaces.Fire Performance
Metac is classed as ‘non-combustible’, achieving an A1 Euroclass rating (the best attainable).Recycled Content
Metac is manufactured from up to 80% recycled glass.Variants Details
