Internal wall insulation

Warmer walls for older homes

Solid-wall and period properties around Bath lose a lot of heat through their walls. We fit internal wall insulation, breathable thin cork and targeted bay window insulation, then finish it neatly and ready to decorate.

Thin cork insulation

A breathable, space-saving cork system for Bath and Warminster properties where every millimetre of room matters. Cork is well suited to older walls that need to breathe, and its slim build-up means you keep more of your floor space than with thicker boards.

  • Breathable, good for older walls
  • Slim build-up that saves room space
  • Ideal where thicker insulation will not fit

Targeted insulation for cold bay windows, a common weak spot in older Bath homes. We insulate the walls and reveals around the bay, then finish neatly so the room feels warmer and is ready to decorate.
