Internal Wall Insulation for Mount Merrion homes
Some Mount Merrion owners prefer not to change the look of their semi when the rest of the road matches, and internal insulation lets them insulate walls without altering the street. It suits the solid-block phases of the estate, done room by room, and is often timed with a kitchen or bedroom renovation. We assess which walls are solid and which are early cavity before recommending it.
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 internal wall insulation works
Internal wall insulation lines the inside face of external walls with insulated boards or a stud and insulation system, then replasters. It suits homes where the exterior has to stay as it is: red-brick period terraces, protected structures, Architectural Conservation Areas, or a single elevation that cannot be wrapped externally.

How much room space does internal insulation take?
Usually 60mm to 100mm off each external wall, depending on the system. On a typical room that is a small loss of floor area for a large gain in comfort.
Is internal insulation safe for solid brick walls?
It is when the system suits the wall. Solid brick needs moisture to be able to move, so we choose between breathable and vapour-closed systems after assessing the wall and detail the junctions carefully.
Can I live in the house during the work?
Yes, we work room by room so the rest of the house stays usable. Each room is out of use for one to two days.
