If you plan on using the loft/attic as storage space, you should lay boards above the joists. The insulation will not be thick enough if it is only between the joists.

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.

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 sound transmission by sealing any cracks or crevices that airborne noises can travel through.

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 eliminates any sounds caused by hot water flowing from the heating system heating the wooded joints. They expand, creak or groan.

It also keeps heat from escaping to upper floors, which causes lower floors to become colder, which in turn makes them require more heat to keep warm. The upper floors 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 attic, loft, or flat roof can reduce heat loss and lower your heating bills.

Rolls of mineral wool insulation can be used if access is good and the loft joists have regular dimensions. The insulation is first laid between the horizontal beams, or joists, that make up the loft floor. Next, another layer is laid at right angles so the insulation can be covered to the desired depth.

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. You should leave enough air space between insulation layers and boards 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 loss from living spaces. By making your loft space cool, you can prevent damp or condensation from developing. You may need to increase ventilation if you install loft insulation yourself.

You can also insulate the loft by fitting insulation between the rafters. These are the sloping timbers that form the roof. You have two options: rigid insulation boards that are carefully cut to your specifications or foam insulation spray between the 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. It is important to ensure that your roof remains dry before installing insulation.

If you plan to use your loft for heating, you’ll need to make a room in the roof.

If you are planning to use your loft for living, or you already have it, you will need insulation between the heated space and unheated area.

Your house must allow air to flow freely in order for it to stay fresh, dry, and healthy. A professional installer will ensure that your house does not have any obstructions or seals. Do not cover grilles, airbricks, or vents if you are DIY-insulating.

If you have difficulty accessing your loft, a professional can install the appropriate insulation. The specialist equipment will blow the insulation material into any difficult space. They can use mineral wool fibre, treated with cellulose, or polyurethane.

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 the loft is accessible, has no damp problems, and is not on a flat roof you can likely insulate it 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 your loft already has insulation, you need to ensure that it is effective.

Loft floor rolls are the traditional choice. These roll out along the loft floor. They are quicker to lay than insulated flooring boards. They come in both loose and encapsulated (blankets) rolls. These can be used to create base and top 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. Make sure you read the entire article to ensure you are fully equipped to insulate your loft floor safely.

There may be some insulation in your home, but it may not work well. 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. Sometimes, loft floors can be as small as 25mm in depth for older properties.

There is no need to remove 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.

The spacing of your loft floor’s joists will determine the width roll you choose. This is because insulation is rolled between these joints. It is best to choose one that matches your joist spacing. This reduces the need for trimming.

The insulation’s required thermal resistance. Another alternative is to measure the thickness of insulation if you only lay loft rolls. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
