Loft Insulation

Loft Insulation

Heat rises, and if your home is not sufficiently insulated approximately a third of your home’s heat will escape through the roof. You can prevent this loss by sufficiently insulating your loft.

Loft insulation could reduce your fuel bills by a third, as the insulation will significantly lessen your need to heat your home. Aside from the financial benefits, you will also enjoy a much more comfortable living environment.

Solarwall have installed insulation since 1977. We are members of the National Insulation Association and the InstaGroup.

Key Benefits

  • Improved levels of comfort. An insulated home is warmer and cosier.
  • Fuel bill savings. Your fuel bills will be lower as your home won’t require as much heating to reach a comfortable temperature.
  • Stops sudden temperature changes. These can agitate bronchitis and asthma.
  • Keeps your home cooler in summer.  The insulation provides an effective solar over-heating barrier to help keep heat out in summer.
  • Can help to reduce condensation. Loft insulation will help prevent the formation of condensation in your loft, which can lead to damp issues developing throughout the rest of your home.
  • Increases the value of your home. Having loft insulation installed improves your Energy Performance Certificate (EPC) rating, which you will need to provide if you come to sell your house. The better your EPC rating is, the more attractive your property will be when selling.
  • Preserves the environment.  Installing loft insulation will reduce your carbon emissions because you won't be using your heating as often.

How it works

Loft insulation is laid between and over the joists on the loft floor of your property. It works by creating a barrier to the hot air that is rising from the lower levels of your house towards your roof. The air pockets in insulation trap the hot air and prevent it from being lost into the atmosphere. Solarwall usually install InstaFibre insulation.

If you have previously had your loft insulated, you will want to ensure it meets the current standard of 270mm (10.5 inches). If it does not meet this standard, your existing loft insulation can be topped up to a level that will guarantee that you are receiving maximum savings and that the smallest possible amount of heat is being lost from your house.
