Plan to store things in your loft or attic, so you’ll need to put boards on top of the joists. It is not enough to insulate between the joints if you do not cover the entire area.

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. The dense composition of the material and the application process result in a completely airtight enclosure. It blocks sound from outside, including traffic, pedestrianised streets, and areas near airports.

Spray foam insulation also stops sounds from within a structure being transmitted to floors below, above, or into adjacent rooms. 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 the transmission and propagation of airborne noises by sealing every crack and crevice.

Spray foam insulation also dampens, if it is not eliminated completely, sounds that could originate from beneath a floor such water flowing through pipes. It completely surrounds the pipes, keeping them in place and preventing them from rattling. 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 escaping from the upper floors. Lower floors become cooler which, in turn, requires more heat. Upper floors then become too hot.

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 you have access to your loft joists and it is easy to use, mineral wool insulation rolls can be used. 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 either fit timber battens between the joists or buy plastic legs that are specifically designed to fit the joists. To prevent condensation, make sure there is a vent between the insulation boards and the insulation.

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.

You can also insulate the loft by fitting insulation between the rafters. These are the sloping timbers that form the roof. You have two options: rigid insulation boards that are carefully cut to your specifications or foam insulation spray between the rafters.

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

The air needs to move freely through your house in order to keep it fresh, dry and healthy. A professional installer will ensure that your house does not have any obstructions or seals. Do not cover any grilles, vents, or airbricks if you do DIY insulation.

A professional can install blown insulation in a loft that is difficult to reach. They will use special equipment to blow the appropriate insulation material into any 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 cost savings will depend on the size of the flat roof.

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.

Cold draughts could be caused by the cooler loft air. Fit an insulated roof hatch and place strips of draught-exclusion material at 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 is an effective way to lower heating bills, be more efficient and warm your home in the winter. It doesn’t matter if you have insulation in place, but it is important to get the right amount to make it work.

Loft floor rolls: These are the most traditional option. They are rolled up along the loft’s ceiling. They are quicker to lay than insulated flooring boards. They are available in loose and encapsulated rolls (blanket) and can be used for both top and bottom layers. They can be boarded with stilts to make a raised platform for storage.

These tips and recommendations aren’t listed in this article’s tool and material list. 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. Older properties may have a loft floor as low as 25mm deep.

It doesn’t have to be removed from your loft floor insulation. To reach the recommended level, simply add one or more layers to it. We will discuss how much to recommend in the next section.

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 thermal resistance. Alternativly, you can measure the insulation’s thickness if you are only laying loft rolls. You can find more information in the section “How to calculate loft floor insulation thickness”
