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 is much more effective than fibreglass, rock wool or polystyrene panels when used inside walls, roofs, floors and attics. 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.

It also prevents sound generated from within a building from reaching adjacent floors or the floors below them. 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, which is flexible and packed with millions of tiny air bubbles, absorbs vibrations from the floor and wooden members. It also inhibits sound transfer through the floor. Spray foam insulation reduces transmission of airborne sounds by sealing and filling every crevice.

Spray foam insulation reduces, if any, the sound of water passing through pipes. The insulation completely surrounds pipes to prevent them from moving and keeps them secure. 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 prevents heat from escaping the upper floors. This causes the lower floors of the building to cool down, which then requires more heat in order 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 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.

To ensure sufficient insulation, raise the floor height so that you can place enough mineral wool below the new floor. 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. You should leave enough air space between insulation layers and boards 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 blocks heat escape from living spaces. Therefore, loft insulation will cool your loft space, which can lead to condensation or damp problems. You may need to increase ventilation if you install loft insulation yourself.

A second way to insulate your loft, is to install insulation between and over rafters. These sloping woods make up 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. We don’t recommend this. Before you add insulation to your roof, make sure it is in good shape.

If you plan to use your loft for heating, you’ll need to make a room in the roof.

If you’re planning on using your loft as a living room, or it’s being used already, make sure all walls and ceilings that divide a heated and unheated space have insulation.

To keep your home fresh, dry, and healthy, air must flow in and out. Good installers will ensure that there is no obstruction or sealing of any inadvertent ventilation. When DIY insulation is done, ensure that you don’t cover any vents grilles or airbricks.

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

Flat roof insulation is a great way to save money on heating, as well as loft insulation. The size of your flat roof will affect the savings.

If the loft is accessible and not covered by a flat roof or damp, you may be able to insulate the loft 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. 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. 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. These are easier than insulated floor boards and require less tools and take less time to lay. They are available in loose and encapsulated rolls (blanket) and can be used for both top and bottom layers. You can use stilts or boards to board them. This will create a raised platform that is suitable 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.

There may be some insulation in your home, but it may not work well. It could be that the insulation has been compressed with storage boards or not being topped up for a while. Older properties may have a loft floor as low as 25mm deep.

There is no need to remove loft floor insulation. To get the recommended amount, just add one to three layers more. 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 insulation is rolled between these joints. It is best to choose one that matches your joist spacing. This reduces the need for trimming.

The insulation must have the required thermal resistance. You can also measure the insulation’s thickness using a faster method if you’re only installing loft rolls. This section will provide you with information on how to calculate the thickness of your loft floor insulation.
