Loft Insulation Frequently Asked Questions

What are the benefits of loft insulation?

Approximately one third of the heat within your property will escape through the roof if not correctly insulated. Significant savings on heating bills will be enjoyed whilst also increasing home comfort.

What is loft insulation?

Loft insulation is man-made mineral fibre in a roll form. Often referred to as “Quilt” the material generally used is made from silica sand, creating a wool-type product also known as glass wool. Old style loft insulation was known to be itchy, but modern insulation has been re-designed to be soft to touch and virtually non-itchy. Regardless though, it will be delivered into your loft sealed inside a plastic package.

How long does loft insulation last?

Providing the material is left undisturbed, it is maintenance free and should last indefinitely.

What arrangements are made for the installation?

A member of our production department will contact you to make a mutually convenient arrangement for the installation to be undertaken. Alternatively, you may telephone 0116 2366 523 and ask for your local Domestic Loft Department. If you are also having cavity wall insulation installed, this appointment will be made together so there is no need to call again.

What happens to items stored within the loft space?

You must ensure that items stored within the loft space are removed prior to our crews arriving. Small items such as Christmas trees and suitcases will be moved within the loft by our crews, but our technicians are not able to move either general or large amounts of items.

Please ask if you are unsure.

What happens to stored items after the installation?

We must stress that once we have finished, the joists will not be visible and we recommend that you do not access the loft without the use of crawling boards and only still if you are aware of the exact position of the joists. We do not recommend replacing stored items due to this risk. However, if you do wish to replace items, then the joists should be raised and boarding placed for stored items.

Do I need to provide anything?

No, our installation teams provide all of their own equipment including lights and ladders.

What is the procedure regarding boarded areas?

Boarded areas will need to be removed prior to the date of installation. If you do not wish to remove the boarded area but wish to proceed with the installation, standard industry best practice is for the insulation to be laid over the boards.

How is loft insulation installed?

Our technician will arrive on the agreed date in a vehicle distinctively sign written as Mark Group. The technician will be wearing our traditional red and blue uniform, but we request that you remember to ask to see their identification.

The material will be in sealed bags, which will be carried into your loft and opened within the loft space. The insulation will be laid between and across the joists. The loft hatch will also be insulated. We must stress that once we have finished, the joists will not be visible and we recommend that you do not access the loft without the use of crawling boards and only still if you are aware of the exact position of the joists.

How long does it take?

The installation should take between 1-2 hours to complete.

Is there much mess?

No, a small amount of dust may fall from the loft hatch, (depending how long it has been since the hatch was last opened) which will be cleared by the crew and all packaging will be removed from your home.

How much energy will I save?

You will save around 1.5 tonnes of CO2 per year compared to an un-insulated loft, and around £200 per year on your energy bills.
