Soltherm Endurance 75 Silicone EWI System

Soltherm Endurance 75 Silicone EWI system is an industry leading, external wall insulation system incorporating Dual Density Mineral Wool (DDMW) insulation that achieves 75-year durability credentials with ETA.

Soltherm Endurance 75 Silicone EWI system features patented Soltherm Cross Knot Fixings & Soltherm Clamping Rings, which the provide significantly higher levels of safety contribute to the systems ability to perform effectively for over 75 years.

Soltherm Cross Knot Fixings unique design means that it can achieve industry leading pull through resistances when used in conjunction with DDMW insulation.

Soltherm Clamping Rings are an innovative fixing solution that prevent delamination between the base coat and DDMW insulation, providing much-improved system performance at window interfaces, external corners and parapets.

Soltherm Endurance 75 Silicone EWI system is finished with silicone render, available in over 300+ colours and is suitable for use on both new build & refurbishment projects without a height restriction, subject to Soltherms High Rise & Complex Project Policy.
