Direct external wall insulation contractor serving Donegal. Certified Sto and Baumit systems with SEAI grant deductions.
We install certified Baumit external wall insulation systems across County Donegal, serving homeowners in Letterkenny and surrounding areas.
In County Donegal, external wall insulation is generally considered exempted development under planning regulations, provided it does not change the essential character of the area. However, if your building is listed as a Protected Structure or lies in a Conservation Area, you should consult with Donegal County Council before beginning installation.
We process the SEAI grant paperwork on your behalf and deduct the grant amount directly from your invoice.

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 Donegal. Isotherm deducts this directly from your invoice.
