Which Loft Insulation Is Best?

When it comes to loft insulation, there are a few different types of insulation to choose from.

Each type of loft insulation has its own distinct advantages and disadvantages, and each may or may not suit the needs and requirements of your project.

Here are some of the types of loft insulation

What Are The Different Types Of Loft Insulation?

The main types of loft insulation are:

Sheet Loft Insulation

As the name would suggest, sheet insulation comes in the shape of sheets or boards and is designed to insulate the slanted sides of your roof.

It can be ordered to fit specific measurements as well as having the ability to be coated in moisture resistant or fire-resistant coating.

This is a beneficial method of loft insulation in the sense that the boards can be thick.

Therefore more insulation, as well as being able to be covered with plasterboard, ideal for insulating a loft conversion.

However, this can be an expensive method of insulating your loft.

Blanket Loft Insulation

Probably on of the more common and more popular loft insulation methods, blanket loft insulation is rolls of rock, mineral, felt or glass fibre with a foil backing.

It is an ideal choice of loft insulation as it can be easily installed by yourself and is great for insulating wall cavities that lay exposed.

However, some of the materials can be highly irritable, so protective gear must be worn when installing.

Blanket loft insulation can also be quite bulky, and may not be suitable for smaller loft spaces.

Blown Fibre Loft Insulation

This is an excellent method of insulating your loft, however it will need to be installed by a professional as the insulation has to be blown between the gaps of the joists in the roof.

It is relatively fast to install when carried out by a professional.

It can also be made from recycled materials making it a great choice for a sustainable household.

However, it can be very costly and it is not ideal for lofts that are draughty.

Loose-Fill Loft Insulation

This type of loft insulation is generally made from different types of materials that are lightweight or granular, including the likes of cellulose fibre, mineral wool or cork granules.

It can also be made from recycled material.

It is great for repairing or topping up existing insulation and can fit nicely between oddly shaped joists as well as any obstructions.

However, it may eventually become loose in lofts that are draughty.

IMPORTANT: Protective gear must also be worn when using.

Which Loft Insulation Is The Best?

If you are planning to insulate your loft by yourself in a cost-effective way, then blanket loft insulation is probably the best option.

Blown fibre loft insulation is also effective if you can afford to have it carried out by a professional.

However, it is best to use whichever loft insulation is most suitable for your loft.
