Attic Insulation in Lucan

Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Lucan village, Esker, Adamstown and the surrounding area.

Attic Insulation for Lucan homes

Lucan's 1970s and 1980s estate attics are about as straightforward as attics get: standard trussed roofs, a water tank, and insulation that has usually never been topped up. A full upgrade to current depth, with tank and pipe lagging, a sealed hatch and raised boarding for storage, is typically done in a day and is one of the best value grant-aided upgrades for these homes.

How homes in Lucan lose heat

The 1970s and 1980s estates are the bulk of the housing and typically sit at C3 to D2, held back by empty or partly filled cavities, thin attic insulation and early glazing. Some earlier estate houses were built with hollow block rather than cavity walls, which need external insulation instead. Adamstown homes are newer and mainly benefit from airtightness checks.

Typical housing: Village terraces and pre-war semis near the centre, 1970s and 1980s estate housing through Esker and the middle of the town, and newer Adamstown developments.

Planning: The village core has conservation context; the estates generally allow external insulation as exempted development.

How attic insulation works

Heat rises, and in a typical Irish semi a poorly insulated attic is one of the biggest single sources of heat loss. Many attics still have the 50mm to 100mm of glass wool laid when the house was built, compressed by storage boxes and disturbed by electricians. Current practice is around 300mm of mineral wool laid in two cross layers, or an equivalent depth of other materials.

Attic Insulation in Lucan: questions

Do you carry out attic insulation in Lucan?

Yes. We cover Lucan and the surrounding Dublin area, including Lucan village, Esker, Adamstown. Village terraces and pre-war semis near the centre, 1970s and 1980s estate housing through Esker and the middle of the town, and newer Adamstown developments.

Is planning permission an issue for attic insulation in Lucan?

The village core has conservation context; the estates generally allow external insulation as exempted development. We check the planning position for your specific house at the free survey, before any work is specified.

Is there a grant for attic insulation in Lucan?

SEAI individual grants for attic insulation are up to €2,000 for a detached house (€2,500 for first-time buyers and qualifying welfare recipients), with fixed lower amounts for semi-detached and terraced homes and apartments. Homes must have been built and occupied before 2011. Grant amounts are set nationally by SEAI and change from time to time, so check seai.ie before applying. We confirm what your home is likely to qualify for during the survey.

How deep should attic insulation be?

Around 300mm of mineral wool, laid in two cross layers, meets current practice for most attics. Many older Dublin homes have 100mm or less, often compressed.

Can I still use my attic for storage?

Yes. We install raised platforms so stored items sit above the insulation rather than crushing it, which keeps the insulation working.

Will insulating the attic cause condensation in the roof?

Not if the eaves ventilation is kept clear and the hatch is sealed, which is part of every installation. Blocking eaves ventilation is the common mistake that causes condensation, and we avoid it.
