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.

  • Area under the cold water tank left clear so it cannot freeze
  • Eaves kept clear, with ventilation trays where air could be blocked
  • Mineral wool to 270 to 300 mm across the whole loft floor
