Types of Loft Insulation

Rolls of Mineral Wool

  • Description: Made from molten glass or rock that is spun into fibers and formed into rolls or batts.
  • Benefits: Fire-resistant, durable, and offers excellent thermal insulation.

Blown-In Loose-Fill Insulation

  • Description: Composed of loose materials such as cellulose, fiberglass, or mineral wool that is blown into the loft space.
  • Benefits: Fills gaps and hard-to-reach areas effectively, providing thorough coverage.

Rigid Foam Boards

  • Description: Panels of rigid foam, typically made from polystyrene or polyurethane, cut to fit between roof joists.
  • Benefits: High insulation value per thickness, lightweight, and moisture-resistant.

How is Loft Insulation Installed?

Assessment

  • Inspection: A professional surveyor inspects the loft to determine its suitability for insulation.
  • Suitability: Factors such as existing insulation, ventilation, and the condition of the roof space are considered.

Preparation

  • Clearing the Loft: The loft area is cleared of any debris or stored items to allow for proper installation.
  • Air Sealing: Gaps and cracks are sealed to prevent air leakage before the insulation is laid.

Installation

  • Laying Insulation Rolls: For mineral wool, the rolls are laid between and over the joists in the loft, ensuring even coverage.
  • Blowing Loose-Fill Insulation: Loose-fill insulation is blown into the loft using specialized equipment to ensure it reaches all areas.
  • Installing Foam Boards: Rigid foam boards are cut to fit and placed between the roof joists, sometimes combined with other types of insulation for added efficiency.

Finishing

  • Ensuring Proper Ventilation: After installation, it’s important to check that the loft is adequately ventilated to prevent moisture build-up.
