Attic Insulation in Mount Merrion
Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Mount Merrion, UCD, Stillorgan and the surrounding area.
Attic Insulation for Mount Merrion homes
Mount Merrion's semis have simple pitched attics, often topped up once in the 1980s or 1990s with insulation that has since settled. A full upgrade to current depth with a sealed hatch and lagged tank is quick, grant-aided and usually the first step in our recommendations for these homes.
How homes in Mount Merrion lose heat
Because the estate was built to a small number of house types, the same weaknesses come up again and again: walls that may be early cavity or solid block depending on the phase, attic insulation from a later top-up that has settled, uninsulated floors and draughty original hatches. Ratings are typically D1 to E1.
Typical housing: 1950s and 1960s estate housing on consistent layouts, mostly semi-detached, with generous gardens.
Planning: Most of Mount Merrion allows external insulation as exempted development, though consistency of the streetscape is worth considering.
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 Mount Merrion: questions
Do you carry out attic insulation in Mount Merrion?

Is planning permission an issue for attic insulation in Mount Merrion?
Most of Mount Merrion allows external insulation as exempted development, though consistency of the streetscape is worth considering. 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 Mount Merrion?
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.
