Insulation is essential for the optimum thermal and acoustic performance in your new home.

Thermal/Acoustic Insulation

• It is the responsibility of the builder or project manager to provide insulation to all areas in accordance with the SAP and thermal calculations.

• No gaps should exist around insulation in walls, ceilings and roofs

• If insulation is broken or is poorly fitted between studs, ceiling joists or roof joists, permitting a gap at sides or ends, thermal and acoustic performance can be adversely affected.

• To meet Building Regulations, walls around all bathrooms and WC’s, including soil stacks, should be fully insulated.

Wall Insulation

• Insulation is required in all walls (including internal walls and dormer windows)

• External and internal walls should be fully filled with insulation (typically 140mm mineral wood in external walls and 90mm in internal walls).

• In separating walls the insulation should be draped behind the electrical
  installation. Where heating or other water pipes are contained in external walls, extra insulation must be taken behind such pipes.
