Sto Exterior Insulation Finish Systems
Sto is the innovative world leader in cladding, coating and restoration systems. Sto was a pioneer in advance coatings and building technologies in Europe long before coming to the U.S. in 1979. In fact, Sto introduced the first Exterior Insulation and Finish Systems (EIFS) to the European market in 1963. Our expertise in EIFS is unmatched.
EIFS gives you the freedom of design that no other cladding materials can offer. Your possibilities in colors, details, form and texture are endless. EIFS also provides your building with a protective blanket of continuous insulation, and enables excellent strength-to-weight ratios. So your building will not only be beautiful, but well-insulated, cost-effective and lasting. Why EIFS? The question should be, "Why choose anything else?"
Superior Value in a Superior Wall Cladding
A proven choice for all climates and substrates, Sto Exterior Insulation and Finish Systems are advanced wall cladding assemblies engineered for performance, design freedom, and durability. Whatever your project, Sto provides the best value in a wall cladding-integrated EIF Systems of unequaled aesthetic and technological elegance that are user friendly to install and cost-effective.
Reduced Air Infiltration and Heat Loss
Continuous exterior insulation provides significant energy savings and superior interior climate control and comfort.
- Exterior air and moisture infiltration at foundation and wall joints, wall outlets and vents is reduced by as mush as 55%, compared to typical construction.
- Heat loss through the walls, which accounts for up to 40% of heat loss in non-EIFS construction, is greatly reduced.
The dew point is the temperature, at the given relative humidity, where water vapor condenses. As the diagrams show, an EIF System moves the dew point outside the wall, greatly reducing the possibility of moisture condensing and possibly freezing inside the wall and causing damage.
The System
- Reduces heat loss by wrapping the structure in a insulation blanket.
Sto EIFS offer better insulation and higher R-values because rigid expanded polystyrene (EPS) boards are attached adhesively as a continuous blanket around the exterior of the structure, eliminating the many thermal breaks characteristic of between-the stud insulation and claddings attached with nails and screws. A broad range of R-values EPS in varying thickness from 3/4" to 4" (19-101 mm).
That Can Cause Thermal Shock
Thermal shock is the sudden and potentially damaging expansion or contraction of wall surfaces in response to extreme changes in temperature. When a building is enveloped with an EIF System, the most dramatic temperature changes take place in the exterior insulation blanket and the EIFS wall assembly remains flexible enough to expand and contract, protecting the building structure from damage and keeping inside wall temperatures more constant and comfortable.
