Insulation Materials

SILRES® BS silicone emulsions are used to improve the performance of mineral insulation materials. SILRES® BS creates a hydrophobic surface-bound silicone network that reduces capillary water uptake while retaining permeability to water vapor. As a result, thermal conductivity is optimized over the long term and the treated insulating materials are effectively protected against moisture-induced damage.


Hydrophobic impregnation of insulating materials used in the following:

  • Exterior insulation
  • Wall insulation
  • Roof insulation
  • Loose-fill insulation


  • Maximum reduction of capillary water uptake
  • Minimal reduction in water vapor permeability
  • Extensive penetration depth
  • Adequate alkaline resistance
  • Resistance to UV light, high and low temperatures
  • Surfaces not rendered shiny or tacky
  • No yellowing
  • Environmentally compatible
  • Saves energy and reduces CO2 emissions
  • A more comfortable indoor climate
