Research has shown there is increasing evidence that long-term environmental noise can have a negative influence on people’s health and wellbeing; and there’s an increasing focus on the noise we are subjected to at home.

In fact, in the most recent Government National Noise Attitude Survey [1], it was discovered that a whopping 48% of British people felt that their home life was spoilt to some extent by noise – with homeowners living in loft spaces. This was especially noticeable within high-density urban areas particularly subject to external noise from trains, planes and traffic, and even noise from adverse weather conditions such as wind, rain and hail.

This is why Isover created Metac, which now offers housebuilders the opportunity to create a well-insulated loft space, with added acoustic benefits, at no additional cost.

What’s more, independent tests by the University of Salford have shown that when installed into a pitched roof at rafter level, Metac can provide a weighted external sound reduction of up to 49 dB (Rw)[2]. For housebuilders looking to differentiate their offer, this cost effective, superior acoustic solution is therefore ideal.

With a thermal conductivity of 0.034W/mK, the Metac range offers housebuilders a cost effective glass mineral wool solution that enables them to meet a wide range of U-values, helping future occupiers to live more comfortably within their property, using less energy and reducing their household bills.

But the benefits of Metac don’t stop there…

Research revealed that installers routinely experienced problems with finding insulation that is quick and easy to fit accurately between the pitched roof rafters, whilst minimising gaps and waste on site. This is a problem that Metac has solved as it easily friction-fits between the rafters, without creating any air gaps or slumping.

The rolls are also extremely resilient, lightweight and easy to handle, and they can easily be cut to size on site with very little wastage. Plus, the off-cuts can be re-used to fill other smaller gaps and spaces.

Metac is also manufactured from up to 80% recycled glass and is non-combustible, achieving an A1 Euroclass fire rating, the best attainable.
