Attic Insulation in Naas
Bringing the attic up to current depth with the details that keep it working: ventilation, hatch and services. Covering Naas town centre, Sallins, Punchestown and the surrounding area.
Attic Insulation for Naas homes
Naas's 1990s and 2000s homes generally have 100mm to 150mm of attic insulation, which is worth topping up to current depth, especially before fitting a heat pump. It is a quick job on these standard trussed roofs. Town-centre homes have older roofs that need more careful work around ventilation.
How homes in Naas lose heat
The 1990s and 2000s estates were built under older building regulations with partial-fill cavities and modest attic insulation. They usually rate C, and the gains come from attic top-ups, checking cavity fill and sealing airtightness gaps. Town-centre homes have solid walls and need a different approach.
Typical housing: Town-centre period terraces and pre-war housing, with 1990s and 2000s estate housing across the wider catchment.
Planning: Town-centre conservation context can apply to older homes; 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 Naas: questions
Do you carry out attic insulation in Naas?
Yes. We cover Naas and the surrounding Co. Kildare area, including Naas town centre, Sallins, Punchestown. Town-centre period terraces and pre-war housing, with 1990s and 2000s estate housing across the wider catchment.
Is planning permission an issue for attic insulation in Naas?
Town-centre conservation context can apply to older homes; 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 Naas?
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.
