Insulation materials and methods
Glass wool
The most commonly used insulation material for blown-in insulation, non-combustible (A1) with high moisture resistance.
Rock wool
Mineral insulation material with high fire protection and excellent sound insulation, among other things for basement ceiling insulation.
Cellulose
Sustainable alternative for blown-in and roof insulation.
Expanded polystyrene (EPS)
Cost-effective insulation material for blown-in insulation and ETICS.
Perlite
Mineral blown-in insulation material for cavities.
SLS
Blown-in insulation material for cavities in double-leaf masonry.
Wood fibre
Recycling-based insulation material as a sustainable option.
Foam glass granulate
Historically used in cavity wall insulation from the 1960s–1980s.
Calcium silicate boards
Insulation material for interior insulation, e.g. in listed buildings.
Blown-in insulation (cavity wall insulation)
Minimally invasive method for filling cavities in double-leaf masonry, usually completed in 1–2 days.
External thermal insulation composite system (ETICS)
Façade insulation with polystyrene or mineral wool for single-leaf walls.
