Plan to store things in your loft or attic, so you’ll need to put boards on top of the joists. It is not enough to insulate between the joints if you do not cover the entire area.

It is much more effective than fibreglass, rock wool or polystyrene panels when used inside walls, roofs, floors and attics. The dense composition of the material and the application process result in a completely airtight enclosure. 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, which is flexible and packed with millions of tiny air bubbles, absorbs vibrations from the floor and wooden members. It also inhibits sound transfer through the floor. Spray foam insulation reduces transmission of airborne sounds by sealing and filling every 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 eliminates any sounds caused by hot water flowing from the heating system heating the wooded joints. They expand, creak or groan.

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.

In an uninsulated house, 25% of heat escapes through the roof. Insulating your attic, loft, or flat roof can reduce heat loss and lower your heating bills.

You can use mineral wool insulation rolls if you have easy access and your loft joists remain regular. The insulation is first laid between horizontal beams called joists. Once that layer has been laid, another layer of mineral wool insulation is added at right angles.

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.

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

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.

A second way to insulate your loft, is to install insulation between and over rafters. These sloping woods make up the roof. Either rigid insulation boards can be carefully cut to the required size or foam insulation can be sprayed between each rafter.

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.

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

For your home to remain fresh, dry, healthy and clean, it needs air flow. 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 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 could help you save similar heating bills as loft insulation. The size of your flat roof will affect the savings.

You can probably insulate your loft yourself if it is accessible and does not have damp problems. If there are damp issues or more complex insulation needs, a professional should be hired.

Your loft hatch could become colder due to the cooler air. Fit an insulated roof hatch and place strips of draught-exclusion material at the hatch edges.

Insulating your ground floor can help you keep your home warm and reduce your carbon footprint.

Insulating a loft is an effective way to lower heating bills, be more efficient and warm your home in the winter. Even if the loft already has insulation in place, it is essential to use it at its best.

Loft floor rolls: These are the most traditional option. They are rolled up along the loft’s ceiling. These are easier than insulated floor boards and require less tools and take less time to lay. They come in both loose and encapsulated (blankets) rolls. These can be used to create base and top layers. You can board them over with stilts to create a raised storage platform.

These tips and recommendations aren’t listed in this article’s tool and material list. It is important to make sure that you have all the information you need before you start insulation your loft floor.

Even though insulation is often present in homes, some may not be effective. This could happen if the insulation isn’t topped up regularly or has been compressed by storage board. Sometimes, loft floors can be as small as 25mm in depth for older properties.

It’s not necessary to remove loft floor insulation. To get the recommended amount, just add one to three layers more. 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 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 required 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.
