StoTherm Masonry Insulation
Insulation Systems for Concrete Masonry, In-situ or Pre-cast Concrete Walls
StoTherm Masonry Insulation is an exterior insulation finishing system (EIFS) for concrete masonry, in-situ or pre-cast concrete walls. Consisting of 40 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 and savings.
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.

Benefits at a glance
StoTherm is one of the world's most successful facade insulation systems. As the first exterior insulation finishing system (EIFS), it was developed from the outset with a focus on safety and long-term material behaviour and has since been continually improved. StoTherm has one of the lowest complaint rates thanks to its high system reliability and durability.

StoTherm Armat Insulation System
StoTherm Armat is a BRANZ appraised insulation and render system installed on a variety of masonry substrates, consisting of EPS StoTherm Insulation Panels fixed with anchors which avoid thermal bridging.
The StoTherm panels are basecoat to straighten any irregularities. Followed by StoArmat render and glass fibre mesh, providing engineered reinforcement to reliably dissipate tensile, seismic and shear stress. Finished with perfectly interlocking components: Stolit fibre-reinforced coloured finishing render plus StoColor; creating a 4mm weather tight reinforcement system for reliability and protection that surpasses the facade durability requirements.
Installations are carried out by a Sto Registered Licensed Building Practitioner with the added protection of a StoArmat 15 or 20+ Year Warranty and StoService Assurance, guaranteeing building code compliant materials are used and application meets building code standards, including a service plan for long-term security.
