APPLICATION OVERVIEW
Insulation in cold lofts is installed in a number of layers with the first layer being laid between ceiling joists, and subsequent layers being laid at right angles to the ceiling joists, with all edges butt jointed to prevent thermal
bridging and unwanted heat loss.
The principle consideration is thermal performance. Our loft insulation solutions provide excellent levels of thermal resistance in relation to cost of installation as thickness is largely unrestricted.

WHY MINERAL WOOL?
Mineral Wool provides the best combination of thermal, fire safety and acoustic performance.
Mineral Wool is easier to install correctly than other insulants such as rigid boards because it adapts to any slight imperfections in the substrate and knits together, eliminating any air gaps. Evidence shows the absence of air gaps is crucial to achieving real performance in the relevant application.
