Loft Insulation Installer

Loft Insulation

A quarter of heat is lost through the roof if your home is uninsulated.

We can insulate your loft, attic or flat roof simply and effectively to reduce heat loss and reduce your heating bills.

Loft insulation stays effective for at least 40 years and so should pay for itself many times in that time period.

Choosing loft insulation

If your loft is easy to access and has no damp or condensation problems then insulating it should be no problem.
If access is easy and your loft joists are regular we will use rolls of mineral wool insulation. The first layer of insulation is laid between the joists then another layer is laid at right angles to cover the joists and make the insulation up to the required depth.
Choosing loft insulation

Things to consider

Insulating between the joists in your loft will keep your house warmer but make the roof space above it colder.

This means pipes and water tanks in the loft space could be more likely to freeze, so we will talk to you about insulating them.

Because of the cooler air in your insulated loft cold draughts could come through the loft hatch so we can talk to you also about fitting an insulated loft hatch and put strips of draught-excluding material around the hatch edges to help.

How best to insulate your loft
Storage Space
If you plan to use the loft or attic for storage, you will want to lay boards over the joists. Unfortunately, if you only insulate between the joists before doing this, the insulation won’t be thick enough.
Room in the Roof

If you want to use your loft area as a living space or if it is already being used as a living space, then you need to make sure that all the walls and ceilings between a heated room and an unheated space are insulated also.

Sloping ceilings can be insulated with a layer of plasterboard on the inside of the insulation and vertical walls can be insulated the same way. If you have a flat ceiling it can be insulated like a standard loft.

Flat Roofs

A flat roof should preferably be insulated from above. A layer of rigid insulation board can be added either on top of the roof’s weatherproof layer or directly on top of the timber roof surface, with a new weatherproof layer on top of the insulation. This is best done when the roof covering needs replacing anyway. If your flat roof needs to be replaced anyway, you must now insulate it to comply with building regulations.

Having flat roof insulation will save you the same amount as with loft insulation.

Damp Lofts
Insulation stops heat escaping as described earlier which could create or worsen existing damp or condensation problems, it still can be done with well planned ventilation.
