Man Using Measuring Tape in Factory Setting

Warm up your home. Cut down your bills.

Smart. Cost-Effective

At CA Plastering Ltd, we specialise in Internal Wall Insulation (IWI) — a smart, cost-effective solution for improving thermal comfort and energy efficiency in homes across Jersey and the Channel Islands.  Internal Wall Insulation involves fitting insulated boards or batten systems to the inside of external walls. It’s ideal for properties where external insulation isn’t possible — such as listed buildings, granite cottages, or homes in conservation areas.

Benefits of Internal Wall Insulation

  • Lower heating bills — reduce heat loss through solid walls
  • Improved comfort — warmer rooms, fewer cold spots
  • Condensation control — helps prevent damp and mould
  • Discreet installation — minimal disruption, clean finish
  • Eco-friendly — cut your carbon footprint

Our Approach

We offer a complete IWI service, from initial survey to final finish:
  • Thermal assessment and moisture checks
  • Selection of insulation system — PIR boards, mineral wool, or breathable systems

  • Professional installation by our skilled plastering team

  • Plaster finish to suit your interior style

  • Optional upgrades — soundproofing, fire-rated boards, or decorative finishes
