If you plan on using the loft/attic as storage space, you should lay boards above the joists. Insulation will not be thick enough if you insulate 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 blocks sound from outside, including traffic, pedestrianised streets, and areas near airports.

It also blocks sounds from a structure’s walls from reaching other floors, including the floors below. 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 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. It completely covers the pipes and prevents them from rattling. It also eliminates the sound caused by hot water flowing through pipes. The heating system heats wooded Joists, causing them to expand, creak and groove.

It also stops heat from escaping to the upper levels, which makes the lower floors cooler and requires more heat to keep them warm.

If the loft is accessible and free from damp or condensation, insulation should be simple. In many cases, you can do it yourself.

Uninsulated homes let 25% of their heat go through the 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.

To ensure sufficient insulation, raise the floor height so that you can place enough mineral wool 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.

Do not squash the mineral Wool when fitting the boards onto the top. This will cause it to lose its insulation properties.

Insulation blocks heat escape from living spaces. Therefore, loft insulation will cool your loft space, which can lead to condensation or damp problems. Loft insulation can be done by the homeowner, but you might need to increase the ventilation.

A second way to insulate your loft, is to install insulation between and over rafters. These sloping woods 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 will offer to spray insulation directly on the roof, without having to first fix the problem. We don’t recommend this. 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.

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.

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 any grilles, vents, or airbricks if you do DIY insulation.

A professional can install blown insulation in a loft that is difficult to reach. They will use special equipment to blow the appropriate insulation material into any space. They might use treated cellulose, mineral wool fibre or polyurethane foam.

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. Fit an insulated roof hatch and place strips of draught-exclusion material at the hatch edges.

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

Insulating a loft is an effective way to lower heating bills, be more efficient and warm your home in 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 much easier to lay than insulated floors boards. They come in both loose and encapsulated (blankets) rolls. These can be used to create base and top 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. Make sure you read the entire article to ensure you are fully equipped to insulate your loft floor safely.

Even though insulation is often present in homes, some may not be effective. 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. In some older properties, the loft floor may only be 25mm deep.

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. You will find more information about the recommended amount in the article.

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

The insulation’s thermal resistance. Alternativly, you can measure the insulation’s thickness if you are only laying loft rolls. You can find more information in the section “How to calculate loft floor insulation thickness”
