Plan to store things in your loft or attic, so you’ll need to put boards on top of the joists. You won’t get thick insulation if the insulation isn’t thick enough if the insulation is only applied between the joists.

It reduces sound transference by up to 50% when used in walls, attics and roofs. Its dense composition and the application process creates an entirely airtight environment. It keeps out sounds from the environment like traffic, pedestrianised streets and homes near airports.

It prevents sound from being generated within a structure from reaching floors above, below, or into adjacent spaces. 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 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 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 also prevents hot water from flowing through the pipes, which can cause the wooded beams to creak, crackle and expand.

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 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.

To ensure sufficient insulation, raise the floor height so that you can place enough mineral wool 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 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 loss from living spaces. By making your loft space cool, you can prevent damp or condensation from developing. 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 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.

If you are planning to use your loft for living, or you already have it, you will need insulation between the heated space and unheated area.

The air needs to move freely through your house in order to keep it fresh, dry and healthy. Good installers will ensure that there is no obstruction or sealing of any inadvertent ventilation. You should not cover vents, grilles, or airbricks when you are doing 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 might use treated cellulose, mineral wool fibre or polyurethane foam.

Flat roof insulation could help you save similar heating bills as loft insulation. The extent of the flat roof on your property will impact how much savings you receive.

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.

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 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 less difficult to lay than insulated 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 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 happen if the insulation isn’t topped up regularly or has been compressed by storage board. It is possible for loft floors to be as low as 25mm (deeper) in older properties.

It’s not necessary to remove loft floor insulation. To get the recommended amount, just add one to three layers more. The article will provide more details about how much you should be consuming.

The spacing of your loft floor’s joists will determine the width roll you choose. This is because the insulation rolls between these joists. We recommend selecting one that is close to your joist spacing. It will reduce the need to trim.

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. For more information, see the section ‘How do I calculate the thickness of loft floor insulation?
