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 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 stops sound infiltration from the outside environment such as traffic or pedestrianised streets.

It also blocks sounds from a structure’s walls from reaching other floors, including the floors below. Spray foam insulation could reduce the amount of noises generated by structures such as running showers or washing machines.

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 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 completely surrounds the pipes, keeping them in place and preventing 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 from escaping to the upper levels, which makes the lower floors cooler and requires more heat to keep them warm.

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

Uninsulated homes let 25% of their heat go through the roof. 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 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. This can be done by installing timber battens along the joists or by purchasing purpose-built plastic leg that attach to the joists to support the new floor. To prevent condensation from forming on the boards’ undersides, it is important to ventilate the air gap between insulation and boards.

When you attach the boards to the board, make sure not to squash the mineral wool. This will lower its insulation.

Insulation stops heat from escaping to living spaces. If your loft is not cool enough, it could make existing damp or condensation worse. Consider increasing ventilation if you’re installing loft insulation by yourself.

You can also insulate the loft by fitting insulation between the rafters. These are the sloping timbers that form the roof. You have the option of using rigid insulation boards carefully cut to size or foam insulation sprayed between your 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 something that we do not recommend. It is important to ensure that your roof remains dry before installing 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.

Your house must allow air to flow freely in order for it to stay fresh, dry, and healthy. An experienced installer will not block or seal any intended ventilation. You should not cover vents, grilles, or airbricks when you are doing 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 can use mineral wool fibres or treated cellulose 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.

You can probably insulate your loft yourself if it is accessible and does not have damp problems. Professional installation is recommended for those with damp problems and more complicated insulation systems.

Cooler air could cause cold draughts to enter your loft hatch due to insulation. 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 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 the loft already has insulation in place, it is essential to use it at its best.

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 can be purchased as either loose (blanket), or encapsulated (blanket), and can be used to make both top and base 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. You should ensure that you’ve read everything before you begin to insulate your loft.

While insulation may be present in most homes, it may not have the right level of effectiveness. This could happen if the insulation isn’t topped up regularly or has been compressed by storage board. 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. To reach the recommended level, simply add one or more 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. It is best to choose one that matches your joist spacing. This reduces the need for trimming.

The insulation must meet the requirements for thermal resistance. Another alternative is to measure the thickness of insulation if you only lay loft rolls. This section will provide you with information on how to calculate the thickness of your loft floor insulation.
