1. Roof and Loft Spaces

Up to 25% of heat loss occurs through uninsulated roofs. Installing Sisalwool in loft areas can significantly reduce this loss. Its flexible batts fit snugly between joists, providing comprehensive coverage.

Installation Tips:

  • Preparation: Ensure the loft is clean and any existing insulation is assessed for effectiveness.
  • Layering: Apply Sisalwool batts between and over joists to achieve the desired insulation depth.
  • Ventilation: Maintain adequate ventilation to prevent condensation.

2. Walls

Walls account for approximately 35% of heat loss in homes. Sisalwool is suitable for both internal and external wall insulation, enhancing thermal efficiency.

Internal Wall Insulation:

  • Application: Attach Sisalwool batts to the interior side of external walls, followed by a breathable plaster finish.
  • Benefits: Improves insulation without altering the building's exterior appearance.

3. Floors

Insulating floors can prevent up to 15% of heat loss. Sisalwool's natural fibres provide effective underfloor insulation.

Installation Methods:

  • Suspended Floors: Secure Sisalwool batts between floor joists, ensuring they are supported to prevent sagging.
  • Solid Floors: Lay Sisalwool insulation boards over the existing floor, followed by a suitable floor covering.

4. Windows and Doors

While Sisalwool isn't used directly for windows and doors, ensuring these areas are well-sealed complements the overall insulation strategy.

Recommendations:

  • Draught Proofing: Use draught excluders and sealants to minimize air leaks.
  • Curtains and Blinds: Install thermal curtains or blinds to reduce heat loss.
