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 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.

It also prevents sound generated from within a building from reaching adjacent floors or the floors below them. Spray foam insulation would dramatically reduce the noises that are often generated in a structure.

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 transmission of airborne sounds by sealing and filling every crevice.

Spray foam insulation is also effective in dampening, if no longer completely eliminating, any sounds that might be emanating from a floor like water running 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 escaping from the upper floors. Lower floors become cooler which, in turn, requires more heat. Upper floors then become too hot.

If the loft has no condensation or damp problems and is easily accessible, insulation will be very easy.

Uninsulated homes lose 25% of their heat through their roofs. Insulating your loft or attic is a great way to cut heat loss and save money on heating.

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.

You can raise the floor to get sufficient insulation. 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. To prevent condensation from forming on the boards’ undersides, it is important to ventilate the air gap between insulation and boards.

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. 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 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. This is not something that we recommend. 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.

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

The air needs to move freely through your house in order to keep it 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.

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 can use mineral wool fibre, treated with cellulose, or polyurethane.

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

If the loft is accessible, has no damp problems, and is not on a flat roof you can likely insulate it yourself. 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 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 classic option. They are laid along the loft’s floor. They are quicker to lay than insulated flooring boards. They can be purchased as either loose (blanket), or encapsulated (blanket), and can be used to make both top and base layers. To create a storage platform, they can be boarded using stilts.

These are not recommended items or tips that were included in the list of tools and materials. Make sure you read the entire article to ensure you are fully equipped to insulate your loft floor safely.

Although insulation is present in many homes, it might not be as effective as you would like. 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. Older properties may have a loft floor as low as 25mm deep.

It’s not necessary 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.

Your loft floor’s spacings will dictate the width of your roll. This is due to the insulation being rolled between these beams. We recommend that you choose one that is as close as possible to your joist spacing. This will minimize the need to trim excess.

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?
