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.

It reduces sound transference by up to 50% when used in walls, attics and roofs. The dense composition of the material and the application process result in a completely airtight enclosure. It stops sound infiltration from the outside environment such as traffic or pedestrianised streets.

It prevents sound from being generated within a structure from reaching floors above, below, or into adjacent spaces. 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 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 airborne noise transmission by sealing all cracks and crevices.

Spray foam insulation reduces, if any, the sound of water passing through pipes. The insulation completely surrounds pipes to prevent them from moving and keeps them secure. It eliminates the sound that is made when hot water flows through pipes from heating system. This causes wooded joints to expand, creak, and 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 your loft is easily accessible and does not have condensation problems, insulation should be straightforward.

In an uninsulated house, 25% of heat escapes through the roof. Insulating your roof, attic, and loft is a good way to reduce heat loss. It will also reduce your heating bill.

If it’s easy to access your loft and your joists are straight, you can use rolls mineral wool insulation. 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.

You can raise your floor to provide enough insulation. 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.

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. 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. This is not something we recommend. Like any type of insulation you should ensure that your roof is in good repair before adding insulation.

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

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 can use mineral wool fibres or treated cellulose or polyurethane.

Flat roof insulation may save you the same amount as loft insulation on your heating bills. The extent of the flat roof on your property will impact how much savings you receive.

If the loft is accessible and not covered by a flat roof or damp, you may be able to insulate the loft yourself. Professional installation is recommended for those with damp problems and more complicated insulation systems.

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 groundfloor is a great way for your property to stay warm as well as lowering your energy bills.

Insulating a loft in your home is one of most cost-effective ways to reduce heating bills. 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 more traditional option. They are rolled along the loft’s floors. They are much easier to lay than insulated floors boards. These rolls can be used to create top and base layers. You can board them over with stilts to create a raised storage platform.

These suggestions and recommended items aren’t included in this article’s list of materials or tools. 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.

It doesn’t have to be removed from your loft floor insulation. To achieve the recommended amount, you can just add one or several 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 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 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. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
