Underfloor insulation is a cost-effective way to keep your Lancashire home warmer and reduce energy bills. It works by adding a layer of insulation beneath your floor, acting as a thermal barrier to prevent heat from escaping and cold air from rising.

Depending on your flooring type, underfloor insulation can be fitted using:

• Mineral Wool Rolls – fitted between timber joists.

• Spray Foam Insulation – applied underneath suspended floors with minimal disruption.

• Rigid Foam Boards – laid over solid concrete floors.

The result is a more comfortable living environment, lower energy use, and long-term savings.

How Can I Tell What Type of Floor I Have?

The type of insulation you need depends on whether your home has suspended timber floors or a solid concrete floor.

• Suspended Timber Floors

  • Look for air bricks on the outside of your home, located just above ground level.

  • Homes with chimneys and bay windows often have suspended floors.

  • These floors need airflow to prevent damp, so ventilation must be maintained.

• Solid Concrete Floors

  • More common in newer Lancashire homes.

  • If you don’t see airbricks, it’s likely a solid floor.

Our surveyors at Wise Energy Solutions will confirm the type of flooring during the inspection.

Types of Underfloor Insulation

Solid Concrete Floor Insulation

• Rigid Foam Boards can be installed above or below the concrete.

• Installing the above requires chipboard flooring on top, which may increase the floor height and necessitate adjustments to skirting boards, sockets, and doors.

• Installing the below is only possible when replacing the existing concrete floor.

Suspended Timber Floor Insulation

• Mineral Wool Insulation – floorboards are lifted and insulation is fitted between joists.

• Spray Foam Insulation – installed on the underside of floorboards using robotic technology, requiring only a small access hatch with minimal disruption.

Both methods create a reliable thermal barrier, cutting heat loss and reducing draughts.
