What material do you install?
We use glass fibre insulation, which stops the heating from escaping through your roof.
Do I need to make any preparation for the installation?
The installers need good access to the loft so you may need to remove items stored in the loft if you have a lot of them. If you have only a few smaller objects stored then our installers can probably work around these and move them whilst fitting the material.
What is the recommended thickness?
The current regulations under the EEC programme states that a minimum 270mm of loft insulation is required.
I already have some insulation in the loft.
Any existing insulation can be left in the loft and an additional layer added to it to bring it up to the required minimum thickness. It does not matter how long the existing insulation has been in the loft it still retains its insulant value.
Cavity Wall Insulation
How long does cavity wall insulation last?
For the lifetime of the building.
How long will it take to carry out the installation?
Most properties take around 2-3 hours.
Is the cavity wall insulation guaranteed?
Yes - a Guarantee is provided by CIGA (Cavity Insulation Guarantee Agency) - this is a 25-year guarantee and applies to the property, not the person, so you need to keep it safe with other documents for your property. You will need this document if you sell your house. We will apply for the Guarantee on your behalf.
