A2 Masonry Stone Wool Silicone Render System

Stone Wool Render System solutions from ROCKWOOL Wall Systems are designed for masonry substrates where fire performance, thermal efficiency and long-term façade durability are essential. This A2 Masonry Stone Wool Silicone Render System combines non-combustible stone wool insulation with a robust silicone render finish, creating a high-performance external wall insulation solution for new build, refurbishment and high-rise projects.

Using A1 non-combustible stone wool insulation, the system achieves an A2-s1,d0 fire classification to BS EN 13501-1 and can be used on buildings of any height. ROCKWOOL stone wool insulation also supports breathability, thermal performance and acoustic improvement, making the system suitable for residential, education, healthcare, commercial and social housing schemes.

Finished with our Silicone Render 4S, the system provides a durable, water-repellent and low-maintenance façade finish designed to withstand the demands of the UK climate. ROCKWOOL Wall Systems’ technical team can support architects, contractors and specifiers with specification guidance, U-value calculations, standard details and project-specific advice.
