Loft or Roof Insulation?

In comparison, lofts are usually cheaper and easier to insulate than roofs. But, if your loft is being used, or will be used as a living space, you’ll need to have the roof insulated.

Does Loft Insulation work?

Did you know… Around a quarter of the heat produced by your home will be lost through the roof if it hasn’t been insulated properly.

Having an insulated loft will reduce your energy usage and lower your bills. You can insulate your loft with a variety of insulating materials. In a typical loft, insulating materials are placed between and over the joists of the loft space.

  • Batt or blanket loft insulation is available in rolls of foil-backed felt, rock, glass or mineral fibre and is the most recognised form of insulation.
  • Loose-fill loft insulation is made from a variety of granular, lightweight materials. Typically, cork granules, mineral wool, or cellulose fibre. Recycled newspaper is now being used as an eco-friendly alternative.
  • Sheet loft insulation is designed for insulating the sloping sides of the roof and comes in the form of firm boards. Some boards are available with a fire and moisture-resistant, decorative covering.
  • Blown-fibre loft insulation will require a professional contractor. The insulation is blown into the gaps between joists.

What is Roof Insulation?

If you have converted, or are converting, your loft into another room, such as a bedroom, then roof insulation is a must. The roof can be insulated by using roof insulation materials such as rigid insulation boards between the rafters, or foam, or loose fill. Plasterboard is then fitted on top before decorating.

What Insulation is used in Walls?

Wall insulation comes in various types, depending what kind of wall you want to insulate.

Cavity Wall Insulation

A cavity wall is made up of two walls with a gap in between – or ‘cavity’. Generally, the outer wall is made of brick and the inner made of breeze block. The gap between the two walls means that air runs through it lowering the temperature in your home. Therefore, filling the cavity wall with a suitable insulating material will ensure a warmer winter.

Most houses which were built after the 1920’s will more than likely have cavity walls.

Solid Wall Insulation

If your home was built before the 1920s then it is likely to have solid walls made of brick or stone. And, a solid wall will require some form of internal or external insulation to be applied.

Internal Wall Insulation

Internal wall insulation is installed with the application of boards or rolls to the walls. This insulation installation will mean that your floor space is reduced because of the extra thickness of the walls. At times when the walls are unsuitable for boarding, then a stud wall would have to be built, but this will only decrease the size of the room further.

Floor Insulation

While we know heat rises, don’t forget to check the floor. Any gaps or spaces in your floor allow heat to escape.

Suspended Floor Insulation

For this, you will need to take up your floorboards and then lay the insulation, which can be loose-fit or in a roll, between the joists. If you have a basement, rigid boards can be applied to the ceiling which will give added insulation to the room above.

Ceiling Insulation

Most people add ceiling insulation if their house is newly built or being renovated. This is because you will need to remove the whole plasterboard ceiling. However, you won’t have to do this though if you want to insulate a room that is above a garage or a porch.

Certainly, fitting insulation is an effective way of raising your home’s energy-efficiency rating and reducing your bills.
