Suspended Timber Floor Insulation

The main reason for installing thermal insulation under your floors is to prevent heat loss from gaps between the floorboards.

Installing insulation under your floors is a great step towards having full control over your home's temperature. It is a quick way of transforming your home into a more comfortable atmosphere with a balance of temperature. This is done by fixing insulation between the joists beneath your floors, and this can apply for both renovation projects and new houses. Especially in colder areas, it is essential to keep your homes warm and preserve the heat within. Insulation comes in many thicknesses, to achieve the optimum results it is important that you first figure out the right thickness of insulation needed to meet your desired U-value.
