If you plan on using the loft/attic as storage space, you should lay boards above the joists. You won’t get thick insulation if the insulation isn’t thick enough if the insulation is only applied between the joists.

It reduces sound transference by up to 50% when used in walls, attics and roofs. Its dense composition and the application process creates an entirely airtight environment. It stops sound infiltration from the outside environment such as traffic or pedestrianised streets.

It prevents sound from being generated within a structure from reaching floors above, below, or into adjacent spaces. Spray foam insulation can dramatically reduce noise levels in structures by reducing the frequency of certain noises such as talking, hair dryers and telephones, computer printers and office computers, washing machines, running showers and clothes dryers.

Spray foam insulation is flexible but densely packed with millions if minute air bubbles. This will absorb vibrations from the floor as well as the sound waves. Spray foam insulation reduces sound transmission by sealing any cracks or crevices that airborne noises can travel through.

Spray foam insulation also dampens, if it is not eliminated completely, sounds that could originate from beneath a floor such water flowing through pipes. It surrounds pipes securely, preventing them rattling. It also prevents hot water from flowing through the pipes, which can cause the wooded beams to creak, crackle and expand.

It also stops heat escaping from the upper floors. Lower floors become cooler which, in turn, requires more heat. Upper floors then become too hot.

If your loft is easily accessible and does not have condensation problems, insulation should be straightforward.

An uninsulated home loses 25% of its heat through its roof. Insulating your loft or attic is a great way to cut heat loss and save money on heating.

If you have access to your loft joists and it is easy to use, mineral wool insulation rolls can be used. The insulation begins by placing the first layer between the joists. These are the horizontal beams that form the loft’s floor. A second layer is then laid at right angles to cover and seal the joists.

You can raise your floor to provide enough insulation. Timber battens can be fitted across the joists. Alternatively, you can purchase purpose-built plastic legs to fit onto the joists and support your new floor. It is essential to allow ventilation between insulation and boards in order to prevent condensation.

It is important to not squash the mineral fiber when you put the boards on top. This can reduce its insulation.

Insulation stops heat from escaping to living spaces. If your loft is not cool enough, it could make existing damp or condensation worse. You may need to increase ventilation if you install loft insulation yourself.

The insulation can be fitted between and over the roofing rafters, which are the flat timbers that support the roof. You can either use rigid insulation boards which are cut precisely to fit your loft, or spray foam insulation between the roof rafters.

Some companies might offer to repair your roof if it is damaged or leaky. They will spray foam insulation directly onto the roof’s underside without fixing the problem. We don’t recommend this. Before you add insulation to your roof, make sure it is in good shape.

If you would like to use your loft’s roof space as a heating room, then you should take a different approach and make a separate room.

If you’re planning on using your loft as a living room, or it’s being used already, make sure all walls and ceilings that divide a heated and unheated space have insulation.

To keep your home fresh, dry, and healthy, air must flow in and out. Good installers will ensure that there is no obstruction or sealing of any inadvertent ventilation. When DIY insulation is done, ensure that you don’t cover any vents grilles or airbricks.

If the loft is not easy to access, a professional can install blown insulation. This specialist will use special equipment that can blow insulation into difficult spaces. They can use mineral wool fibre, treated with cellulose, or polyurethane.

Flat roof insulation can save you as much on heating costs than loft insulation. The amount of flat roofing on a property will determine how much savings you get.

If the loft is accessible and not covered by a flat roof or damp, you may be able to insulate the loft yourself. If there are damp issues or more complex insulation needs, a professional should be hired.

Cooler air could cause cold draughts to enter your loft hatch due to insulation. You can prevent this by fitting an insulated loft hatch, and placing strips of draught-exclusion material around hatch edges.

Insulating your ground-floor is a great idea to keep your property warm and lower your energy bills.

Insulating a loft can be one of the best ways to lower your heating bills, save money on energy and keep your home warm during the winter. It doesn’t matter if you have insulation in place, but it is important to get the right amount to make it work.

Loft floor rolls are the traditional choice. These roll out along the loft floor. They are less difficult to lay than insulated boards. They can be purchased as either loose (blanket), or encapsulated (blanket), and can be used to make both top and base layers. To create a storage platform, they can be boarded using stilts.

These tips and recommendations aren’t listed in this article’s tool and material list. Before you start insulation of your loft floor, make sure you have read all instructions.

Even though insulation is often present in homes, some may not be effective. This could be due to insulation being compressed by storage boards placed over it or if it hasn’t been topped up in the long-term. Older properties may have a loft floor as low as 25mm deep.

It’s not necessary to remove loft floor insulation. To achieve the recommended amount, you can just add one or several layers to it. You will find more information about the recommended amount in the article.

Your loft floor’s joint spacings will affect the width of the roll. This is because insulation is rolled between these joints. We recommend you select one that’s close to the spacing of your joists. This minimizes the need to trim.

The insulation’s thermal resistance. Alternativly, you can measure the insulation’s thickness if you are only laying loft rolls. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
