Transform the Way Your Home Looks and Feels
What is External Wall Insulation (EWI)?
External Wall Insulation (EWI) involves fixing rigid insulation panels to the outside of your home’s walls, then finishing with a modern weatherproof render or cladding.
Result: Your home feels warmer, looks better, and costs less to heat.
Why choose External Wall Insulation?
Our External Wall Insulation System
We use high-performance EWI systems trusted across Ireland and Europe.
- Insulation Boards: Typically 100mm Expanded Polystyrene (EPS) or Mineral Wool
- Fixing Method: Mechanically fixed + adhesive
- Finish Options: Acrylic render, dry dash, brick slip or colour-tinted coatings
- Breathable, waterproof and long-lasting
Is My Home Suitable?
For costs not covered by grants, this scheme offers low-interest loans to homeowners undertaking energy upgrades.
- Solid wall homes (pre-1980s)
- Homes with poor insulation or constant cold spots
- Properties undergoing renovation or redecoration
- Detached, semi-detached and terraced homes with sufficient external space
If your home has cavity walls, Cavity Wall Insulation may be a more cost-effective solution.
