What is loft insulation?
Loft insulation is like a blanket for your home. Mineral fibre wool is laid between the joists along your attic floor or on the rafters that support the roof.
It improves the thermal efficiency of your home by slowing down the loss of heat to the outside which helps you keep your home warmer in winter and cooler in summer.
The placement of your insulation will have an impact on the temperature of the loft itself – insulation between the rafters will keep your loft cool, whereas insulation placed between the rafters keeps the loft a similar temperature of your home.
Loft insulation will last for up to 40 years and, due to its inexpensive cost, will pay for itself in fuel bill savings many times over.
How thick should loft insulation be?
270mm (10.5 inches) is the recommended thickness of loft insulation.
The government’s recommendations for the thickness has increased over the years, therefore if you have pre-existing loft insulation, it may not be the correct depth and should be topped up.
This recommendation represents good value for money, with the balance between cost of the insulation and potential savings taken into account.

You can fit loft insulation and still use your loft for storage
Building extra rafters and boarding can allow you to store items in your loft.
The rafters are fitted above the insulation to provide a storage option.
Items should not be placed directly onto loft insulation as this can flatten the mineral fibre wool and reduce its insulating effect.
If you have a small amount of storage and would like to keep it, installers will work round this as long as the space is less that a third of the loft area.
Insulation can be fitted even if the loft has a low ceiling
Lofts that have limited head room can still be insulated as installers don’t need to be able to stand up to complete installations.
It is common for installers to stick to a minimum height of approximately 1.5m – most lofts are above this.

If you use you loft as a room then your property will not be suitable for loft insulation.
However, you may be able to install room in roof insulation as an alternative.

- The roof needs to be in an inhabitable condition with no presence of damp, mould, rot, flaking timbers or unreliable electrical connections.
