What is loft insulation?

We lay the first layer to the depth of the joists, usually 100 mm, so it fills each bay edge to edge with no gaps. The second layer goes across the joists at right angles, which covers the timber and stops it acting as a cold bridge. More about loft insulation.

  • Cables lifted clear of the insulation where possible
  • Area under the cold water tank left clear so it cannot freeze
  • Eaves kept clear, with ventilation trays where air could be blocked
