We produce the highest quality EWI system in the world. Our mission is to supply innovative building materials, insulation cladding and solutions to the British Market. We want you to feel safe in your home. There are very clear UK Building Regulations referring to Fire Protection Requirements for EWI Systems. The insulation systems are classified in relation to their reaction to fire. Houses up to 2 storeys should be insulated with a system not less than C class (Low Risk). What is the classification for Soltherm systems then? All the mineral wool based systems are classified as class A - they are non-combustible. All the systems with EPS boards are classified as B.The Soltherm insulation systems are adhesively bonded. What does that mean? It simply means, that the adhesive creates an additional barrier against the spread of fire. This barrier is not present in dry fixed systems, which is why the fire on those buildings may spread quickly and pose much more of a threat.
