You will need to cover the joists with boards if you intend to store items in the attic or loft. The insulation will not be thick enough if it is only between the joists.

It dramatically reduces sound transference when used within walls and attics, roofs, floors and roofs. This is in contrast to fibreglass and rock wool as well as polystyrene and polystyreneboards. Its dense composition, and its application process results in an envelope that is completely airtight. It stops sound infiltration from the outside environment such as traffic or pedestrianised streets.

It also prevents sound generated from within a building from reaching adjacent floors or the floors below them. 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 airborne noise transmission by sealing all cracks and crevices.

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 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.

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 flat roof, attic, or loft can help reduce heat loss and decrease your heating costs.

If it’s easy to access your loft and your joists are straight, you can use rolls mineral wool insulation. 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. You can install timber battens on the floor joists. Or, you can use purpose-built legs made of plastic that fit on the leg and support the floor. It is essential to allow ventilation between insulation and boards in order 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 stops heat from escaping to living spaces. If your loft is not cool enough, it could make existing damp or condensation worse. Do not forget to improve ventilation if loft insulation is being installed by you.

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. You have the option of using rigid insulation boards carefully cut to size or foam insulation sprayed between your rafters.

Some companies may offer to repair your roof with foam insulation. This is not something 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.

You must insulate your loft if you plan to use it as a living area or if you have one.

Your house must allow air to flow freely in order for it to stay fresh, dry, and healthy. Installers who are skilled will make sure that you don’t block or seal off any ventilation. You should not cover vents, grilles, or airbricks when you are doing DIY insulation.

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 might use treated cellulose, mineral wool fibre or polyurethane foam.

Flat roof insulation could help you save similar heating bills as loft insulation. The size of your flat roof will affect the savings.

If your loft is easily accessible, doesn’t have damp problems, and has a flat roof, it could be insulate yourself. For those cases when damp is a problem or a more complex insulation system, professional installation should be done.

Cold draughts could be caused by the cooler loft air. You can prevent this by fitting an insulated loft hatch, and placing strips of draught-exclusion material around 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 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 – These are the classic option. They are laid along the loft’s floor. They are less difficult to lay than insulated boards. 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. 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. It could be that the insulation has been compressed with storage boards or not being topped up for a while. It is possible for loft floors to be as low as 25mm (deeper) in older properties.

Good news is that you don’t need to remove existing 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.

Your loft floor’s joint spacings will affect the width of the roll. This is because insulation will be rolled between the joists. 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. If you only want to lay loft rolls, there is an alternative method that measures the insulation thickness. This section will provide you with information on how to calculate the thickness of your loft floor insulation.
