If you live in Dublin or Meath, chances are you’ve heard people talking about “the wrap”.
They’re talking about external wall insulation. It’s one of the most effective upgrades you can make to an older Irish home. It cuts heat loss, improves comfort, and gives the house a fresh new exterior. And yes, it can qualify for SEAI grants.
This guide breaks it down in plain English. No fluff.
What Does External Insulation Involve?
“The wrap” means insulating your home from the outside, not the inside. It’s also not to be confused with Cavity Wall Insulation, which is not a service we provide, but our partners Powell Insulations look after this.
Instead of losing heat through cold block walls, your house gets a continuous insulated layer wrapped around it.
Materials Used
Most systems use:
- EPS insulation boards (expanded polystyrene)
- A reinforced basecoat and mesh
- A weather-resistant decorative topcoat
This system is designed to handle Irish weather. Wind, rain, cold, the lot.
How the Process Works
- Insulation boards are fixed to the external walls
- A basecoat and reinforcing mesh are applied
- A durable, coloured render finish goes on top
- Details like window sills and reveals are finished cleanly
No shortcuts. The finish matters as much as the insulation.
How Long It Takes
For a typical Dublin semi-detached house:
- 7–14 working days, depending on size and weather
You can stay living in the house while the work is done.
Benefits of External Insulation for Homeowners
This isn’t just a cosmetic upgrade. The gains are real.
Lower Heating Bills
External insulation drastically reduces heat loss through walls.
Your home stays warmer for longer. Your boiler works less.
That’s real energy savings year after year.
Better Comfort, Less Damp
- Warmer internal wall temperatures
- Fewer cold spots
- Reduced condensation and mould risk
Older Irish homes feel completely different after insulation is added.
A Fresh New Look
Cracked render, tired pebbledash, stained walls? Gone.
External insulation modernises the exterior and can add serious kerb appeal.
SEAI Grants Available
Homeowners may qualify for funding through the SEAI Home Energy Grants scheme.
Grants can significantly reduce the upfront cost if the work is done by a registered contractor.
