EPS in Construction: Insulation Applications
Expanded Polystyrene (EPS) is used in a range of construction applications, including façades, roofs and floors. Its thermal characteristics, weight and ease of handling vary by product grade, building system and intended use. When correctly specified and installed, EPS insulation can contribute to a building’s thermal performance.
A Proven Track Record in Façade Insulation
EPS can be integrated into building envelopes as façade insulation. When correctly designed and installed as part of a complete building system, it can contribute to the thermal performance of an external wall. Actual energy use, indoor temperatures and greenhouse-gas impacts depend on the overall building design, installation, climate, operation and energy source.

External Thermal Insulation Composite Systems (ETICS) can incorporate white or grey EPS. The appropriate system should be selected according to the building design, required thermal performance, fire-performance requirements and applicable regulations.

EPS can be used in flat-roof insulation systems. Product selection should take account of the roof design, static loads, weather exposure, drainage, moisture conditions, fire-performance requirements and applicable regulations.
Custom-sized EPS insulation boards can be specified for relevant flat-roof applications. Their suitability and performance depend on the complete roof system and installation conditions.
EPS System Boards for Underfloor Heating
EPS system boards can be used in underfloor-heating systems. When correctly specified and installed, they can contribute to the thermal performance of the floor system. Actual energy use and operating costs depend on the heating system, building design, installation, climate, operation and energy source.
EPS in building Design
EPS insulation's role in the construction industry is relevant to building projects where thermal performance is a design requirement. When correctly specified and installed as part of a complete building system, EPS can contribute to the thermal performance of façades, roofs and floors.
With its range of applications, EPS insulation can be considered for different building designs and conditions, subject to the relevant product specifications, installation requirements and regulations. Building performance and environmental impacts should be assessed for the complete building system, taking account of its design, installation, climate, operation and energy source.
