It is much more effective than fibreglass, rock wool or polystyrene panels when used inside walls, roofs, floors and attics. Its dense composition and the application process creates an entirely airtight environment. It stops sound infiltration from the outside environment such as traffic or pedestrianised streets.

Spray foam insulation also stops sounds from within a structure being transmitted to floors below, above, or into adjacent rooms. Spray foam insulation can dramatically reduce noise levels in structures by reducing the frequency of certain noises such as talking, hair dryers and telephones, computer printers and office computers, washing machines, running showers and 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 the transmission and propagation of airborne noises by sealing every crack and 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 surrounds pipes securely, preventing them rattling. 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 escaping from the upper floors. Lower floors become cooler which, in turn, requires more heat. Upper floors then become too hot.

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 loft or attic is a great way to cut heat loss and save money on heating.

Rolls of mineral wool insulation can be used if access is good and the loft joists have regular dimensions. 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. Timber battens can be fitted across the joists. Alternatively, you can purchase purpose-built plastic legs to fit onto the joists and support your 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 blocks heat escape from living spaces. Therefore, loft insulation will cool your loft space, which can lead to condensation or damp problems. Loft insulation can be done by the homeowner, but you might need to increase the ventilation.

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 offer to fix a roof that is leaking or damaged by applying foam insulation directly to the roof. This will not solve the problem. This is not something that we recommend. You must ensure that your roof is in good condition before you apply insulation.

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

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

To keep your home fresh, dry, and healthy, air must flow in and out. An experienced installer will not block or seal any intended ventilation. When DIY insulation is done, ensure that you don’t cover any vents grilles or airbricks.

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 may save you the same amount as loft insulation on your heating bills. The size of your flat roof will affect the savings.

If the loft is accessible, has no damp problems, and is not on a flat roof you can likely insulate it yourself. A professional installer is required for cases where damp problems are present or complex insulation systems are needed.

Cold draughts could be caused by the cooler loft air. Install an insulated loft hatch to prevent cold draughts.

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 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. These are easier than insulated floor boards and require less tools and take less time to lay. 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. Before you start insulation of your loft floor, make sure you have read all instructions.

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. It is possible for loft floors to be as low as 25mm (deeper) in older properties.

It doesn’t have to be removed from your loft floor insulation. You can simply add one or two layers of insulation to the loft floor to achieve the recommended amount. 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 the insulation rolls between these joists. It is best to choose one that matches your joist spacing. This reduces the need for trimming.

The insulation’s required thermal resistance. Another alternative is to measure the thickness of insulation if you only lay loft rolls. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
