For Attics at Ceiling Level install Climowool and KORE Loft insulation between and over the joists. For Pitched Roofs access between rafters and install KORE Lock or Climowool and apply KORE Linear Drylining to studded walls and sloping ceilings.
For Cavity Walls install KORE Fill and for Cavity Blocks install KORE Linear Drylining.
Insulating floors in existing buildings is very costly and disruptive. It is advised to undertake this work if work on the floor needs to be done anyway.
A few other tips for insulating existing homes are:
- Upgrade window and doors
- Insulate pipes and Ducts with KORE Pipe Insulation
- Insulate Hot Water Tanks with KORE Hot Water Jackets
- Insulate Cold Water Tanks with KORE Cold Water Jackets
- Install thermostats
- Seal all draughts around doors and windows with KORE Draught Proofing Solutions
- Insulate behind attic door with Climowool
