Midland Insulation — 14 Common Questions Answered

For a 3-bed semi-detached home, combining pumped cavity wall insulation and 300mm attic insulation typically costs €1,000 to €1,900 net after the €2,500 combined SEAI grant (€1,200 cavity + €1,300 attic). For a 4-bed detached house or bungalow, the combined grant is €3,200 (€1,700 cavity + €1,500 attic), leaving a typical net cost of €1,300 to €2,600.

Your home must have been built and occupied before 2011 (confirmed by your 11-digit ESB Networks MPRN connection date) to qualify for SEAI Attic, Cavity Wall, Internal Dry-Lining or External Wall Insulation grants.

During a free survey, the technician drills a 12mm test hole in the mortar joint and inspects the cavity with a digital borescope camera to confirm a clear cavity of at least 50mm.

Graphite-enhanced expanded polystyrene (EPS) bead is injected with a water-basedPVA bonding adhesive so the beads lock together inside the wall, preventing slump if an opening is cut later and blocking moisture from crossing the cavity.

SEAI requires attic mineral wool or glass wool insulation to be topped up to 300mm total depth (100mm between the ceiling joists and 200mm cross-laid at right angles over the joists) to reach a roof U-value of 0.16 W/m²K.

Along with 300mm of mineral wool on the attic floor, the installer fits rigid eaves ventilation trays between the rafters so airflow stays open, lags all cold water pipes and the attic storage tank, and insulates and draught-strips the attic hatch.

Yes, by fitting raised loft legs or a raised timber storage deck above the joists so the 300mm mineral wool underneath is not squashed flat.

External wall insulation fixes 100mm to 150mm of rigid insulation board to the outside of hollow-block, solid-concrete or stone walls that have no cavity to pump, finished with fibreglass mesh and breathable silicone render.

SEAI pays €3,000 for an apartment, €3,500 for a mid-terrace house, €6,000 for a semi-detached or end-terrace house, and €8,000 for a detached house or bungalow.

Yes. Once the insulation work is finished, an independent BER assessor publishes your post-works Building Energy Rating certificate, and SEAI adds an extra €50 grant towards the BER cost.

Pumping the cavity walls of a 3-bed semi or detached bungalow takes 1 day from outside the house, and rolling out 300mm attic insulation takes 4 to 6 hours, so both are usually finished in a single day.

No. You must have your formal SEAI Letter of Offer in place before any insulation work begins on site, or SEAI will refuse the grant.
