Attic Insulation in Dundrum

Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Dundrum Village, Ballinteer, Churchtown and the surrounding area.

Attic Insulation for Dundrum homes

Attics in Dundrum's Ballinteer and Sweetmount estates are usually simple pitched roofs with original insulation well below current depth, and a top-up is quick and grant-aided. Pre-war homes near the village can be trickier: shallow roof spaces, lath-and-plaster ceilings and sometimes no ventilation at the eaves, which we add or protect as part of the job so the roof timbers stay dry.

How homes in Dundrum lose heat

The two stocks lose heat differently. Pre-war homes have solid or early cavity walls, suspended timber floors and draughty sash windows, often rating E or worse. The estates have cavity walls that were frequently built empty, original 100mm attic insulation and leaky attic hatches, usually landing around C3 to D2.

Typical housing: Period red-bricks and pre-war semis near the village and Churchtown, with 1960s to 1980s estate housing across Ballinteer, Wesley and Sweetmount.

Planning: Parts of Dundrum village sit within an Architectural Conservation Area, which can rule out external insulation on front elevations.

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 Dundrum: questions

Do you carry out attic insulation in Dundrum?

Yes. We cover Dundrum and the surrounding Dublin area, including Dundrum Village, Ballinteer, Churchtown. Period red-bricks and pre-war semis near the village and Churchtown, with 1960s to 1980s estate housing across Ballinteer, Wesley and Sweetmount.

Is planning permission an issue for attic insulation in Dundrum?

Parts of Dundrum village sit within an Architectural Conservation Area, which can rule out external insulation on front elevations. 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 Dundrum?

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.
