Boards should be laid over the joists if the loft or attic is to be used for storage. 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. 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 could reduce the amount of noises generated by structures such as running showers or washing machines.

Spray foam insulation that is both flexible, and filled with millions and millions of air bubbles will absorb the vibrations of the floor. The floor’s wooden members and floor will also be affected. 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 surrounds pipes securely, preventing them 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 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 roof, attic, and loft is a good way to reduce heat loss. It will also reduce your heating bill.

You can use mineral wool insulation rolls if you have easy access and your loft joists remain regular. 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.

To ensure sufficient insulation, raise the floor height so that you can place enough mineral wool 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. You should leave enough air space between insulation layers and boards to prevent condensation.

It is important to not squash the mineral fiber when you put the boards on top. This can reduce its insulation.

Insulation blocks heat escape from living spaces. Therefore, loft insulation will cool your loft space, which can lead to condensation or damp problems. Do not forget to improve ventilation if loft insulation is being installed by you.

The insulation can be fitted between and over the roofing rafters, which are the flat timbers that support the roof. You can either use rigid insulation boards which are cut precisely to fit your loft, or spray foam insulation between the roof rafters.

Some companies will offer to spray insulation directly on the roof, without having to first fix the problem. This is not something we recommend. You must ensure that your roof is in good condition before you apply insulation.

You can use your loft to heat the space, but you will need to create a separate room on 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.

For your home to remain fresh, dry, healthy and clean, it needs air flow. Good installers will ensure that there is no obstruction or sealing of any inadvertent ventilation. Do not cover any grilles, vents, or airbricks if you do DIY insulation.

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 may use mineral wool fibres, treated cellulose foam or polyurethane.

Flat roof insulation could help you save similar heating bills as loft insulation. The amount of flat roofing on a property will determine how much savings you get.

If your loft is easily accessible, doesn’t have damp problems, and has a flat roof, it could be insulate yourself. Professional installation is recommended for those with damp problems and more complicated insulation systems.

Your loft hatch could become colder due to the cooler air. This can be prevented by installing an insulated hatch in your loft and putting strips of draught-exclusion material around the hatch edges.

Insulating the ground floor of your property is a great option to keep it warm and also lower your emissions.

Insulating a loft in your home is one of most cost-effective ways to reduce heating bills. 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. They are much easier to lay than insulated floors boards. They can be purchased as either loose (blanket), or encapsulated (blanket), and can be used to make both top and base layers. They can be boarded with stilts to make a raised platform for storage.

These are not recommended items or tips that were included in the list of tools and materials. You should ensure that you’ve read everything before you begin to insulate your loft.

Although insulation is present in many homes, it might not be as effective as you would like. 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. In some older properties, the loft floor may only be 25mm deep.

There is no need to remove loft floor insulation. To achieve the recommended amount, you can just add one or several layers to it. You will find more information about the recommended amount in the article.

The spacing of your loft floor’s joists will determine the width roll you choose. This is because the insulation rolls between these joists. We recommend you select one that’s close to the spacing of your joists. This minimizes the need to trim.

The insulation’s 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?
