Plan to store things in your loft or attic, so you’ll need to put boards on top of the joists. Insulation will not be thick enough if you insulate only between the joists.

This material reduces the sound transference significantly when it is used within walls, attics or roofs, as well as floors, in comparison with fibreglass, rock wool, and polystyrene board. Its dense composition and the application process creates an entirely airtight environment. 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 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 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 sound transmission by sealing any cracks or crevices that airborne noises can travel through.

Spray foam insulation reduces, if any, the sound of water passing through pipes. It surrounds pipes securely, preventing them rattling. It also eliminates the sound caused by hot water flowing through pipes. The heating system heats wooded Joists, causing them to expand, creak and groove.

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.

An uninsulated home loses 25% of its heat through its 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. 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 prevents heat from escaping living spaces. It will make loft space more comfortable and less humid. This could lead to dampening or worsening existing 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 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 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 must insulate your loft if you plan to use it as a living area or if you have one.

Your house must allow air to flow freely in order for it to stay fresh, dry, and healthy. Installers who are skilled will make sure that you don’t block or seal off any ventilation. Do not cover any grilles, vents, or airbricks if you do DIY insulation.

You can have blown insulation installed if your loft is difficult to access. A professional will use specialist equipment and blow the right insulation material into every space. They may use mineral wool fibres, treated cellulose foam or polyurethane.

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

If the loft is accessible, has no damp problems, and is not on a flat roof you can likely insulate it yourself. For those cases when damp is a problem or a more complex insulation system, professional installation should be done.

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

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

Insulating your loft is a great way to cut down on heating costs and save energy. It also keeps the home warm in winter. Even if your loft already has insulation, you need to ensure that it is effective.

Loft floor rolls are the traditional choice. These roll out along the loft floor. 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. You can use stilts or boards to board them. This will create a raised platform that is suitable for storage.

These items and tips are not included in the article’s list. You should ensure that you’ve read everything before you begin to insulate your loft.

Even though insulation is often present in homes, some may not be effective. 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. Sometimes, loft floors can be as small as 25mm in depth for older properties.

Good news is that you don’t need to remove existing 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 spacing of your loft floor’s joists will determine the width roll you choose. This is because insulation will be rolled between the joists. 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. If you only want to lay loft rolls, there is an alternative method that measures the insulation thickness. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
