Wykamol ISO-THERM Wall Insulation Adhesive
Wykamol ISO-THERM Adhesive is a ready-to-use mineral adhesive specifically formulated for the installation of Wykamol ISO-THERM Thin Internal Wall Insulation (TIWI) systems. Based on stabilised potassium silicate and siliceous aggregates, the adhesive provides a durable bond while maintaining high vapour permeability, allowing moisture vapour to pass through the wall system. Designed for low-profile insulation installations, it supports condensation management and is suitable for use in refurbishment, retrofit and conservation projects.
