Does my home need Underfloor Insulation
The first thing you need to understand is whether your home is suitable for underfloor insulation. This depends upon the kind of floors you have in your home: –

Older home with suspended floors – these generally lose the most heat
Solid (concrete) floors – these can be insulated but it can be very costly and requires considerable work
Modern houses – these tend to incorporate slabs of polystyrene insulation a few inches below the concrete floor surface, effectively reducing this type of heat loss.
Whatever your home, there’s still some kind of measure you can take to insulate your floor.

What heat is lost through floors

As the above diagram shows, a poorly insulated house can lose upto 15% of its heat through the floors. Depending on the size and type of your house, you could save upto £75 per year (source Energy Savings Trust)

How do we install Underfloor Insulation
Generally, the installation is done from the underfloor area. The installer will enter the underfloor access hatch and check to see if all areas can be accessed. Once all areas have been assessed by the team, the OmitFit Earthwool insulation is inserted between each joist and pinned in place with netting by our in house installation team. All accessible areas will be insulated.

The installer may need to remove some floor coverings, if the floor is laminate then removing it may cause damage as laminate is not designed to be reused. Carpet can be easily removed and refitted.

A large percent of properties have been built with a very limited underfloor depth. If this is the case the only acceptable way to install this product is to carefully remove the floor covering i.e. Carpets, laminate and every 800 – 1000mm lift a single floorboard from wall to wall and the product will be put in place and netted in sections. This process will be repeated for each room that doesn’t have a sufficient underfloor depth for a person to crawl. Once the areas have been installed the floor covering are carefully put back in the original position.

How long does it take to install Underfloor Insulation
Our experienced underfloor installation team will usually take between 1-4 days depending on the property size.

Is the work guaranteed?
All our underfloor insulation installs come with a 25 year guarantee which is provided by GDGC. The guarantee is provided by a third party because if an installation company should stop trading then the guarantee is still protected.
