Attic Insulation in Stillorgan
Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Stillorgan Village, Mount Merrion, UCD and the surrounding area.
Attic Insulation for Stillorgan homes
Stillorgan's post-war and 1960s houses often have generous, hipped roof spaces. That gives plenty of room for proper depth but a large area to cover, so the gain on a detached house is substantial. We also check for old ventilation openings and missing insulation over bay windows and porches, which are common gaps in these homes.
How homes in Stillorgan lose heat
Some of the earlier post-war houses here were built with solid or hollow-block walls rather than cavities, which a quick borescope check confirms. Typical ratings sit around D1 to E1, held back by walls, thin attic insulation and uninsulated floors. Detached homes have four exposed walls, so wall insulation has a large effect.
Typical housing: Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.
Planning: Little conservation constraint on the estates, so external insulation is usually 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 Stillorgan: questions
Do you carry out attic insulation in Stillorgan?
Yes. We cover Stillorgan and the surrounding Dublin area, including Stillorgan Village, Mount Merrion, UCD. Post-war and 1960s detached and semi-detached houses on generous plots, laid out in classic mid-century Dublin estates.
Is planning permission an issue for attic insulation in Stillorgan?
Little conservation constraint on the estates, so external insulation is usually 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 Stillorgan?
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.
