Thermal Insulation

Installing our range of thermal insulation products is easy and efficient when you follow the relevant guidelines. 

Reducing thermal bridges is a key consideration when installing stone wool – as these can account for heat losses of up to 30 percent, even in an insulated construction³. 

These bridges occur when a surface transfers more heat than the surrounding material. Stone wool insulation, however, is far less conductive than common building materials such as metals. It therefore acts to reduce the transfer of heat when properly installed⁴. 

Top tips:

• Measure insulation boards, slabs or rolls and the space to be insulated accurately, to prevent gaps. This will help to combat thermal bridging even further. 
• Use an appropriate tool to cut the boards and ensure a clean finish.
• Not sure how much you’ll need? Visit the local product page and head to the Tools, Guides & Downloads section, where you’ll find accurate sizes and measurements⁵.

Our products are made from durable stone wool, which has a smart fibre structure and is designed to last the lifetime of your building⁶.

They also harness the 7 Strengths of Stone, providing additional benefits for you and your building:

• Fire safety – stone wool is non-combustible and can resist temperatures above 1,000º C in the event of a fire⁷.
• Water repellence – our products are resistant to rot and mould^{8 9}.
• Noise reducing – insulation boards and slabs help to improve the acoustics of your building, blocking, absorbing or enhancing sounds as required¹⁰.
• Circularity – ROCKWOOL solutions are designed to last the lifetime of your building and can be recycled, when no longer needed, to make new products¹¹.
