Attic Insulation in Leixlip
Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Salmon Leap, Confey, Leixlip Castle and the surrounding area.
Attic Insulation for Leixlip homes
Leixlip's 1970s and 1980s estates have standard pitched attics with original insulation well below current depth. A top-up is a single day's work with a strong return. Newer homes on the outskirts have more insulation but often benefit from a top-up and a sealed hatch.
How homes in Leixlip lose heat
The 1970s and 1980s estates usually have cavities that were built empty or partly filled and original attic insulation, rating D. Newer homes rate B to C and mostly need airtightness work. Village homes near the river have solid walls and can be prone to damp.
Typical housing: Older village homes around the Salmon Leap and Confey, 1970s and 1980s estates through the centre, and 1990s to 2010s estate growth on the outskirts.
Planning: The village heritage core may carry conservation context; estates generally allow external insulation.
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 Leixlip: questions
Do you carry out attic insulation in Leixlip?
Yes. We cover Leixlip and the surrounding Co. Kildare area, including Salmon Leap, Confey, Leixlip Castle. Older village homes around the Salmon Leap and Confey, 1970s and 1980s estates through the centre, and 1990s to 2010s estate growth on the outskirts.
Is planning permission an issue for attic insulation in Leixlip?
The village heritage core may carry conservation context; estates generally allow external insulation. 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 Leixlip?
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.
