- External Wall Insulation (EWI). EWI is an insulation solution we provide were the external walls of a dwelling are solid or consist of hollow block construction and therefore cannot be insulated by conventional methods such as cavity fill.
- Poorly insulated structures cost more to heat and suffer condensation problems and little or no heat is stored within the property. EWI will considerably reduce energy loss, help stop condensation, stop draughts around window frames, reduce heating bills, increase comfort levels and give a new look to the outside of the property. From experience we have found that the client is not only pleased with the new improved thermal qualities of their property, they are also very pleased with the new lease of life it brings to its appearance.
- Only NSAI external insulation certified installers can do the job which would be eligible for the grants.
- For a relatively small outlay your house not only becomes warmer, it also looks like a new house.
- External insulation involves fixing insulation material such as expanded polystyrene slabs to the outer surface of the wall. They are fixed with both adhesive and mechanical fixings. This insulation is then covered with a cement based render to provide weather resistance. A fibre glass mesh is embedded in this render to provide strength and impact resistance. The finish coat is then applied to the system.
- External wall insulation is the most efficient way to insulate an existing building FACT.
- Customers can avail of the €4000 grant aid.
