Floor Insulation in Mount Merrion
Insulating suspended timber and solid ground floors to stop cold floors and draughts at skirting level. Covering Mount Merrion, UCD, Stillorgan and the surrounding area.
Floor Insulation for Mount Merrion homes
Many of Mount Merrion's 1950s and 1960s semis have suspended timber floors in the front rooms and solid floors to the rear. The suspended floors respond well to between-joist insulation and sealing at the skirting, which removes much of the cold air coming up from below.
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 floor insulation works
Ground floors lose heat into the ground and, in older homes, let in a surprising amount of cold air. Period houses with suspended timber floors are often draughty because air moves freely through the ventilated void below and up through gaps between boards and at the skirting.

Can you insulate a suspended timber floor without removing it?
In some homes the floor can be insulated from below through an accessible void, but most Dublin period floors need boards lifted. We assess access before recommending a method.
Will floor insulation stop draughts?
Yes. Much of the cold felt in period homes comes from air moving up through boards and at the skirting. Sealing those gaps is part of the job.
