A quarter of heat may be lost via the roof in an uninsulated house, resulting in higher energy expenditures.

Elite Group’s team of experts has put up a guide for you.


What exactly does loft insulation imply?

Loft insulation is the process of enclosing the area under your roof with a barrier that prevents inside air from escaping and outside air from entering. It may be installed between rafters or joists.

You can be confident that the passage of heat between the outside world and your living area will be minimised regardless of where you apply insulation. This will make your house cooler in the summer and warmer in the winter.

Insulation in the rafters will maintain the warmth in the area between the roof and the walls, while insulation between the joists will warm your living space but produce a frigid loft. So, before you invest in insulation for loft, consider how you will utilise the space.


Is loft insulation required?

The answer is yes if you have a loft or attic area. To boost your home’s energy efficiency, you’ll require roof or loft insulation. Also, to keep your house warm, pleasant, and cosy without placing too much strain on your heating system.


What are the benefits of Loft Insulation?

The following are some of the advantages of loft insulation:

Save money on your energy expenses. Because outside air cannot enter your house, your HVAC system will not have to work as hard. This implies reduced energy use.

Increase the value of the house — A well-insulated home is much more valuable than one that is not. If you decide to sell your property in the future, insulating the loft will help to increase its total value.

Loft Insulation Types

When it comes to installing loft insulation, there are several alternatives to consider. Checking the R-value is crucial since it indicates how effectively the material can resist heat flow. The many kinds of insulation to consider are as follows:


Mineral Wool

It comes in huge rolls known as “batts” and is made from yarn spun from either glass wool or rock wool. It’s then rolled into the area between the loft joists, with the loose yarn being used to fill up any gaps.

It’s a fantastic choice since it conducts heat well and also acts as a sound barrier. It is generally less expensive than other forms of insulation, and its usage has a low environmental impact.

When handling it, use gloves since it may be quite irritating to the skin.


Sheeps Wool

Sheep’s wool is commonly fashioned into rolls, however it may also be purchased as huge tiles in certain situations. It’s long been a popular option since it’s safe and simple to use while also providing excellent sound insulation and heat retention. It’s also 100 percent recyclable and composed of environmentally friendly materials.


Loft Spray Insulation

Spray foam may also be used to generate a thick liquid that is sprayed out over the loft using a special applicator, but this should only be done by a professional. The foam will soon expand to cover any gaps and solidify into a tight blanket.

This alternative is mould, mildew, and bacterium resistant, as well as having a lengthy lifetime.


How Much Money Will Insulating My Loft Save Me?

The amount you may save by adding loft insulation is determined on the thickness of the insulation and the kind of house you have. When compared to an uninsulated house, 270mm of loft insulation can save the following each year on average on energy expenditures.

Detatched House: £380

semi-detached house: £165

Mid-Terrace House: £150

Detached Bungalow: £235


What’s the Difference Between Insulating a Loft and Insulating a Roof?

If you’ve turned your loft into a room, you’ll usually insulate the roof, this is often refered to as ‘Room in Roof Insulation‘. You’ll need to insulate between the rafters in this situation, and you may use a number of materials.

Because you are merely insulating your loft and not using it as a living area, you may use any insulation material in between and above the joists. This is the most cost-effective way to insulate your house.
