Cavity Wall Insulation

Cavity wall insulation is a low-carbon footprint insulation. This insulation is used within walls to create a heat and moisture seal. Cavity wall insulation not only reduces your carbon footprint with heat saved, but also has the lowest Global Warming Potential per equivalent unit of insulation of any insulation product available. This is a perfect match for an environmentally-conscious home.

Why choose Cavity Wall Insulation?

  • High performance insulation material
  • Lasts the lifetime of the building
  • Fast and efficient installation
  • The lowest embodied emissions insulation
  • Moisture and rot resistant
  • Zero waste insulation option

Are grants available for Cavity Wall Insulation?

They certainly are! Under Eco4, if your walls are uninsulated then they have to be insulated under the programme, in order to allow other improvements to also progress. Please note, in order to qualify for a grant, ventilation may need to be upgraded as part of your package of works.
