Achieve Thorough Heat Efficiency with Floor Insulation Boards.

Underfloor insulation is a smart way to boost the thermal performance of a building, reducing energy consumption and lowering heating bills. It helps eliminate draughts commonly found in homes with suspended timber or concrete floors. It can also help decrease noise throughout the property.

For concrete floors, rigid foam boards like PIR Insulation, cost-effective Expanded Polystyrene sheets or Gyproc Plank plasterboards offer excellent thermal efficiency. If fitting insulation on a concrete floor, lay a damp proof membrane, followed by the insulation, and finish with a layer of chipboard flooring.

You can also use these rigid boards to insulate underneath suspended wooden floors. However, mineral wool insulation may be preferable as it’s flexible and easy to pack between floor joists. 


Consider Loft Floor Insulation

In addition to insulating ground, basement or garage floors, you can insulate your loft floor to improve energy efficiency. This task can be done as part of a stylish loft conversion or as an extra measure to prevent heat loss through the roof.
