Wall Insulation

Internal Wall Insulation in Bath

Most people call us because a room is hard to heat: an external wall that's cold to the touch, a draughty bay, or condensation and mould showing up in the same corners each winter. Internal wall insulation warms the surface of the wall so those cold spots are reduced.

Depending on the wall and the depth you can spare, that might be insulated plasterboard, a thinner cork-based system, or insulating just the bay or the one problem wall. Heating and ventilation still play a part, so we talk about those too rather than promising a cure.

Cork insulation

Cork Insulation in Bath

Where a room is too small to lose much depth, or the wall needs to stay breathable, we use a thin internal cork insulation system. It goes on in layers directly to the wall and is finished with a plaster skim, so the result looks like any other wall — just warmer to the touch.

It is a good fit for older Bath homes with solid external walls, bay windows or rooms where standard insulated plasterboard would take up too much space.

Why choose DSB

Plastering and Wall Insulation by One Local Team

DSB Plastering & Wall Insulation is a local team working for homeowners in Bath and the surrounding towns. We take on everyday plastering — skimming walls and ceilings, plasterboarding, covering Artex and making good after leaks or alterations — as well as internal wall insulation for the cold external walls and bay windows that make a room hard to heat.

A lot of the housing around Bath is older and solid-walled, so the right finish isn't always a standard gypsum skim. Where a breathable, lime-compatible plaster suits the wall better, we'll say so, and we use cork systems where a thinner insulating build-up matters. We look at the wall first and recommend from there.

Plastering and insulation together

Because we do both, the insulation and the plaster finish are planned as one job instead of being passed between trades.

Older, solid-walled Bath homes

We work on the solid-walled housing common around Bath and choose the system — including breathable finishes — to suit the wall in front of us.

Clear prices, tidy work

A written price with the work set out plainly, floors and furniture covered, and the room swept before we leave.
