Direct external wall insulation contractor serving Galway. Certified Sto and Baumit systems with SEAI grant deductions.
We install certified Baumit external wall insulation systems across County Galway, serving homeowners in Galway and surrounding areas.

However, if your building is listed as a Protected Structure or lies in a Conservation Area, you should consult with Galway County Council before beginning installation.

SEAI offers grants of up to €8,000 for detached houses, €6,000 for semi-detached/end-terrace houses, €3,500 for mid-terrace houses, and €3,000 for apartments in County Galway. Isotherm deducts this directly from your invoice.
