Application

Suitable for:

  • Pitched roofs
  • External roofs
  • Internal walls
  • Agriculture
  • Floors
  • Underfloor
  • Soffits
  • Timber frame walls


Suitable substrates include:

  • Concrete

Description

Elastospray is a closed cell insulation with low warning potential, as it is free of all ingredients that contribute to global warming due to greenhouse gas effect. The material is suitable for almost all areas of the building envelope and delivers low thermal conductivity owing to its closed-cell structure combined with airtightness, while permitting insulation without thermal bridges. It delivers simple and fast installation, high compressive strength, and water vapour permeability.


Features and benefits:

  • Low thermal conductivity due to closed-cell structure.
  • Air-tight.
  • Insulation without thermal bridges.
  • Water-tight and water resistant.
  • Good mechanical properties.
  • High compressive strength.
  • Hydrofluorocarbon (HFC) free.
  • Appropriate water vapour permeability.
  • Full adhesion to the substrate without the need for primers or mechanical fixings.
  • Extremely low global warming potential (GWP) of 1 and zero ozone depletion (ODP).
  • Manufactured by BASF, the leading global producer of polyurethane spray foam.
  • CE marked and manufactured.
  • KIWA (BDA) Certified.
