If you plan on using the loft/attic as storage space, you should lay boards above the joists. It is not enough to insulate between the joints if you do not cover the entire area.

This material reduces the sound transference significantly when it is used within walls, attics or roofs, as well as floors, in comparison with fibreglass, rock wool, and polystyrene board. Its dense composition and the application process creates an entirely airtight environment. It is able to block sound from the exterior environment (e.g. traffic, pedestrians, etc.) and prevents infiltration in areas where there are airports or heavy industries.

Spray foam insulation also stops sounds from within a structure being transmitted to floors below, above, or into adjacent rooms. Spray foam insulation will dramatically reduce the sound levels of many noises within a structure, including talking, hair dryers (phones), office computers and printers as well as running showers, laundry machines, clothes dryers.

Spray foam insulation is flexible and filled with millions upon millions of microscopic air bubbles. This not only absorbs the vibrations and stops sound from passing through the floor, but also prevents sound from being transferred. Spray foam insulation reduces the transmission and propagation of airborne noises by sealing every crack and crevice.

Spray foam insulation can also dampen, if not completely eliminate, sounds from floors such as water moving through pipes. The insulation completely surrounds pipes to prevent them from moving and keeps them secure. It also prevents hot water from flowing through the pipes, which can cause the wooded beams to creak, crackle and expand.

It also prevents heat from escaping the upper floors. This causes the lower floors of the building to cool down, which then requires more heat in order to keep them warm.

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

Uninsulated homes let 25% of their heat go through the roof. Insulating your attic, loft, or flat roof can reduce heat loss and lower your heating bills.

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. To prevent condensation, make sure there is a vent between the insulation boards and the insulation.

You should not squash the mineral wool while you place the boards on top. This will decrease its insulation value.

Insulation stops heat loss from living spaces. By making your loft space cool, you can prevent damp or condensation from developing. Loft insulation can be done by the homeowner, but you might need to increase the ventilation.

Another way to insulate your loft would be to place insulation between and above the rafters. These are sloping timbers which make up the roof. You have the option of using rigid insulation boards carefully cut to size or foam insulation sprayed between your rafters.

Some companies may offer to repair your roof with foam insulation. This is not something we recommend. It is important to ensure that your roof remains dry before installing insulation.

If you are looking to use your loft as an indoor heating room, you can create a space in the roof.

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.

For your home to remain fresh, dry, healthy and clean, it needs air flow. Good installers will ensure that there is no obstruction or sealing of any inadvertent ventilation. You should not cover vents, grilles, or airbricks when you are doing DIY insulation.

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 may use mineral wool fibres, treated cellulose foam or polyurethane.

Flat roof insulation may save you the same amount as loft insulation on your heating bills. The amount of flat roofing on a property will determine how much savings you get.

You can probably insulate your loft yourself if it is accessible and does not have damp problems. For those cases when damp is a problem or a more complex insulation system, professional installation should be done.

Cooler air could cause cold draughts to enter your loft hatch due to insulation. This can be prevented by installing an insulated hatch in your loft and putting strips of draught-exclusion material around the hatch edges.

Insulating the ground floor of your property is a great option to keep it warm and also lower your emissions.

Insulating your loft is a great way to cut down on heating costs and save energy. It also keeps the home warm in 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 – These are the classic option. They are laid along the loft’s floor. They are less difficult to lay than insulated boards. They come in both loose and encapsulated (blankets) rolls. These can be used to create base and top layers. They can be boarded with stilts to make a raised platform for storage.

These items and tips are not included in the article’s list. Before you start insulation of your loft floor, make sure you have read all instructions.

While insulation may be present in most homes, it may not have the right level of effectiveness. This could be due either to storage boards being placed on top of it, or because the insulation has not been maintained for a long period. Sometimes, loft floors can be as small as 25mm in depth for older properties.

There is no need to remove loft floor insulation. To reach the recommended level, simply add one or more layers to it. We will discuss how much to recommend in the next section.

The spacing of your loft floor’s joists will determine the width roll you choose. This is because the insulation rolls between these joists. We recommend that you choose one that is as close as possible to your joist spacing. This will minimize the need to trim excess.

The insulation’s required thermal resistance. If you only want to lay loft rolls, there is an alternative method that measures the insulation thickness. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
