StoTherm Insulation for Timber
or Steel Frame


Insulation Systems for Cavity Construction



Overview

StoTherm Insulation is an external wall insulation system for timber or steel frame construction. Consisting of 50 to 100mm and over thick EPS StoTherm Panels or StoTherm+ Panels which increase R-values by up to a further 20% for better energy-efficiency.

 

Sto, a world leader in manufacturing insulated render systems has provided over 150 million square metres of insulated cladding to date and has been tried and tested in every climate around the world for proven insulation performance.

StoTherm Armat Insulation System

StoTherm Armat Insulation is a BRANZ appraised, high performance insulation and render system installed over timber or steel frame construction. The system includes StoTherm Panels and uPVC flashings to lock into junctions and joinery forming a neat weathertight seal. 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 and StoService Program, ensuring the materials used and application meets building code standards, including a service plan for long-term security.
