StoTherm Armat Insulation System

StoTherm Armat Masonry Insulation is a BRANZ appraised, high performance insulation and render system installed over masonry construction. The system includes StoTherm Panels, StoTherm Anchors and uPVC flashings to lock into junctions and joinery forming a neat weathertight seal. Render application includes a mineral-basecoat render, followed by StoArmat synthetic render with fibreglass mesh, providing engineered reinforcement to reliably dissipate tensile, seismic and shear stress. Finished in your choice of Stolit coloured finishing render and StoColor facade paint or clear sealer.

 

Installations are carried out by a Sto Registered Contractor (Licensed Building Practitioner), with the added protection of a StoArmat 15 or 20 Year Warranty with StoService Assurance, ensuring the materials used and application meets building code standards, including a service plan for long-term security.
