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.
