Sika Roofing Systems

Thermal insulation is the key to creating a comfortable environment inside of a building. At the same time, it is also the key to saving energy. Sika provides a wide range of high performance thermal insulation specially designed and manufactured for optimal performance as part of the Sika roofing systems.

Eco-efficiency
GWP and thickness of different insulation materials to provide thermal resistance
Global Warming Potential GWP

Expanded polystyrene (EPS) materials have the lowest Global Warming Potential (GWP) for a given thermal performance, whilst mineral wool based systems have the highest GWP, but they have the advantage of being non-combustible. Polyisocyanurate (PIR) materials have the best thermal performance for a given thickness of insulation.

More Value

  • Polyisocyanurate (PIR) materials have the best thermal performance for a given thickness of insulation
  • Extruded polystyrene (XPS) has very high compressive strength and very low water absorption
  • Expanded polystyrene (EPS) is a very cost-efficient insulation material

Less Impact

  • PIR has a lower GWP than most of the other insulation materials analyzed (Climate Protection Solutions)
  • Expanded polystyrene (EPS) materials have the lowest global warming potential (GWP) for a given thermal performance
  • PIR has very low weight compared with other insulation materials with similar insulation properties
