Why choose External Wrap

A properly managed wrap, from scope to handover

The project is planned around the actual home, then documented clearly through installation and completion.

Benefits of external wall insulation

  • Minimal risk of cold spots that cause condensation and mould because EWI can be applied as a continuous covering without gaps. Unlike lining the walls internally, the insulation does not get interrupted at partition walls and floor junctions.
  • Excellent draught-proofing and air-tightness, also thanks to the coverage being continuous.
  • Relatively little disruption to occupants during installation (although some services may need to be temporarily cut off and re-connected).
  • No loss of floor space internally to rooms.
  • Spruces up the exterior of bland looking buildings and can transform shabby exteriors, e.g. giving unloved tower blocks a new lease of life.
  • A new exterior finish means minimal future maintenance.

FAQ

Common questions

Straight answers on quoting, suitability, appearance, timing and grants.

How do I get a quote without a site visit?

Use our photo quote page: enter your Eircode, answer a few questions about the property, and send photos of each elevation. We review the outside from those photos and come back with a quotation — no site visit needed.

How much does external wall insulation cost in Ireland?

Cost depends on wall area, finish, services, access and dwelling type. After your photo enquiry we provide a project-specific quotation. SEAI external-wall-insulation grants range by dwelling type and can be up to €8,000 for eligible homes.

Is external wall insulation suitable for my home?

EWI suits many Irish homes with solid or poorly insulated walls, but suitability depends on wall condition, damp risk, access and planning. We flag anything that needs a closer look during the photo review and survey stage.

Will EWI change how my house looks?

Yes — in a good way. You choose render colour and finish as part of the specification. Sills, vents and details are planned so the wrap looks intentional, not bolted on.

How long does installation take?

Most domestic wraps take about one to two weeks on site, weather permitting. Scaffold, ventilation cores and service adjustments are planned in from the survey.

Who applies for the SEAI grant?
