External Wall Insulation Systems

The use of effective thermal insulation and renovation systems is acquiring growing importance against the background of diminishing resources, rising oil prices and climate change due to increased CO2 emissions. Insulating buildings demonstrates a responsible and forward-looking approach. Optimum results here call for the highest standards of technical reliability. The diverse range of insulation systems available from Sto provides the appropriate characteristics to meet all individual needs and offer crucial advantages in terms of protection from the weather, thermal insulation, fire protection and sound protection.


Sto is able to draw on 40 years of experience in the field of facade insulation to offer architects, planners and applicators a product range that stands for durability and technical reliability. StoTherm Classic has truly lived up to its name, over 70 million square metres having been installed worldwide over a period of 40 years, with barely a complaint received.

The product range covers solutions for all climatic zones, for ever type of substrate and for all needs. The outstanding building physical properties of the products comprising the systems are matched by their simple installation and versatile design scope. The spectrum covers every type of requirement, from the crack- and shock-proof all-rounder StoTherm Classic with the tried and tested EPS Board to the StoTherm Cell ecological system, from the mineral wool in StoTherm Mineral to the seamless StoVentec ventilated rainscreen cladding system.
