Boards should be laid over the joists if the loft or attic is to be used for storage. It is not enough to insulate between the joints if you do not cover the entire area.

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. The dense composition of the material and the application process result in a completely airtight enclosure. It is able to block sound from the exterior environment (e.g. traffic, pedestrians, etc.) and prevents infiltration in areas where there are airports or heavy industries.

It also prevents sound generated from within a building from reaching adjacent floors or the floors below them. 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 that is both flexible, and filled with millions and millions of air bubbles will absorb the vibrations of the floor. The floor’s wooden members and floor will also be affected. Spray foam insulation reduces sound transmission by sealing any cracks or crevices that airborne noises can travel through.

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 covers the pipes and prevents 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 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 has no condensation or damp problems and is easily accessible, insulation will be very easy.

In an uninsulated house, 25% of heat escapes through the roof. Insulating your loft or attic is a great way to cut heat loss and save money on heating.

Rolls of mineral wool insulation can be used if access is good and the loft joists have regular dimensions. The insulation begins by placing the first layer between the joists. These are the horizontal beams that form the loft’s floor. A second layer is then laid at right angles to cover and seal the joists.

You can raise the floor to get sufficient insulation. 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.

You should not squash the mineral wool while you place the boards on top. This will decrease its insulation value.

Insulation stops heat from escaping to living spaces. If your loft is not cool enough, it could make existing damp or condensation worse. Loft insulation can be done by the homeowner, but you might need to increase the ventilation.

A second way to insulate your loft, is to install insulation between and over rafters. These sloping woods make up the roof. Either rigid insulation boards can be carefully cut to the required size or foam insulation can be sprayed between each rafter.

Some companies will offer to spray insulation directly on the roof, without having to first fix 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.

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

For your home to remain fresh, dry, healthy and clean, it needs air flow. Installers who are skilled will make sure that you don’t block or seal off any ventilation. Do not cover grilles, airbricks, or vents if you are DIY-insulating.

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 can use mineral wool fibre, treated with 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. For those cases when damp is a problem or a more complex insulation system, professional installation should be done.

Your loft hatch could become colder due to the cooler air. Install an insulated loft hatch to prevent cold draughts.

Insulating your groundfloor is a great way for your property to stay warm as well as lowering your energy bills.

Insulating a loft is an effective way to lower heating bills, be more efficient and warm your home in the 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 more traditional option. They are rolled along the loft’s floors. They are less difficult to lay than insulated boards. They are available in loose and encapsulated rolls (blanket) and can be used for both top and bottom layers. You can board them over with stilts to create a raised storage platform.

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. 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. The article will provide more details about how much you should be consuming.

Your loft floor’s joint spacings will affect the width of the roll. This is because the insulation rolls between these joists. We recommend you select one that’s close to the spacing of your joists. This minimizes the need to trim.

The insulation must meet the requirements for thermal resistance. Another alternative is to measure the thickness of insulation if you only lay loft rolls. Refer to the section titled “How to calculate the loft floor insulation thickness required” for more details.
