You will need to cover the joists with boards if you intend to store items in the attic or loft. 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 its application process results in an envelope that is completely airtight. It keeps out sounds from the environment like traffic, pedestrianised streets and homes near airports.

It also blocks sounds from a structure’s walls from reaching other floors, including the floors below. Spray foam insulation could reduce the amount of noises generated by structures such as running showers or washing machines.

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 the transmission and propagation of airborne noises by sealing every crack and crevice.

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 completely surrounds the pipes, keeping them in place and preventing them from 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 from escaping to the upper levels, which makes the lower floors cooler and requires more heat to keep them warm.

It is possible to insulate lofts if they are accessible and have no damp or condensation issues.

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 layer is placed between the joists (the horizontal beams that make the loft’s floor) and then another layer is applied at right angles to cover all the joists.

In order to have enough insulation, raise the floor so that enough mineral wool can be fitted below the new floor. This can be done by installing timber battens along the joists or by purchasing purpose-built plastic leg that attach to the joists to support the new floor. It is essential to allow ventilation between insulation and boards in order to prevent condensation.

When you attach the boards to the board, make sure not to squash the mineral wool. This will lower 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. Consider increasing ventilation if you’re installing loft insulation by 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 will offer to spray insulation directly on the roof, without having to first fix the problem. This is not something that we recommend. Like any type of insulation you should ensure that your roof is in good repair before adding insulation.

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.

You will need to insulate the loft walls and ceilings if you intend to use it as your living space.

To keep your home fresh, dry, and healthy, air must flow in and out. A professional installer will ensure that your house does not have any obstructions or seals. Do not cover any grilles, vents, or airbricks if you do DIY insulation.

You can have blown insulation installed if your loft is difficult to access. A professional will use specialist equipment and blow the right insulation material into every space. They might use treated cellulose, mineral wool fibre or polyurethane foam.

Flat roof insulation is a great way to save money on heating, as well as loft insulation. The cost savings will depend on the size of the flat roof.

If your loft is easily accessible, doesn’t have damp problems, and has a flat roof, it could be insulate yourself. If there are damp issues or more complex insulation needs, a professional should be hired.

The cold air from your loft could lead to cold draughts through the hatch. Install an insulated loft hatch to prevent cold draughts.

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. Even if you already have insulation, it is crucial to have the best amount in order to make it effective.

Loft floor rolls – These are the classic option. They are laid along the loft’s floor. They are quicker to lay than insulated flooring boards. They are available in loose and encapsulated rolls (blanket) and can be used for both top and bottom layers. You can use stilts or boards to board them. This will create a raised platform that is suitable for storage.

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.

There may be some insulation in your home, but it may not work well. 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.

Good news is that you don’t need to remove existing loft floor insulation. You can simply add one or two layers of insulation to the loft floor to achieve the recommended amount. We will discuss how much to recommend in the next section.

Your loft floor’s spacings will dictate the width of your roll. This is because insulation is rolled between these joints. 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 must meet the requirements for thermal resistance. You can also measure the insulation’s thickness using a faster method if you’re only installing loft rolls. Refer to the section titled “How to calculate the loft floor insulation thickness required” for more details.
