Approved loft insulation installers

Want to save money on your energy bills? Contact our team at The Loft Doctor and we can insulate your loft, saving you hundreds of pounds every year.

If you currently have no loft insulation, you will find that your house gets cold quickly. Especially so on the top floor, where heat will rise and pass through the ceilings into your loft space.

After a visit from our loft service providers at The Loft Doctor, we can work out how much insulation you will need to fit your loft and keep your house warm.

Or, if you feel like your current insulation is defective, then we can assess your loft and verify whether you would benefit from new insulation.

Carry on reading to find out more about loft insulation, why you need it, and how we can provide it for you.

How does loft insulation work?

Anyone with loft insulation fitted will tell you that it saves you money on your heating bills. But exactly how does loft insulation reduce heat loss?

Loft insulation is made of layers and layers of dense materials that prevent heat from passing through them. Types of loft insulation include materials like fibreglass, rock mineral, plastic fibres, cellulose, or other natural fibres.

If your house is warm, the warm air within it will rise. In an uninsulated home, it will continue to rise until it escapes through the roof and out into the street. This is why some homes don’t collect snow on their roof during winter – or why birds choose to gather on their warm roof!

A house with an insulated loft keeps the warm air within your home, where it heats you and your family.

Best loft insulation

We use rolls of mineral wool insulation to offer you the best efficiency in your loft at an affordable cost.

Our insulation comes foil backed to enhance its properties as an insulator, as shiny foil reflects infrared heat that hits it.

We use rolls that can be cut to size and fit your joists. This also makes it easy to lay loft boarding down too without damaging your insulation.

For lofts with irregular plans or hard to access areas, spray loft insulation can be used. This is not as effective as insulation rolls, but as a cheap alternative it will be sufficient to get the job done in tough to reach areas.

Frequently Asked Questions

Can you insulate a loft hatch?

Loft hatches come with some form of insulation on them as standard, but you may need to check that there is no draft around the edges by creating a seal using foam strips.
If the insulation on your hatch has worn or it came with none, then you can insulate a loft hatch easily by sealing the edges and then installing an insulating later to the inside of the hatch itself.
It’s important that your loft hatch is properly insulated otherwise you will be losing heat from your home into the loft space, and your loft insulation as a whole will therefore be less efficient.

Is loft insulation flammable?

Most loft insulation materials are fire-resistant to some degree, although none of them are completely fireproof.
The highest rated insulation is classed as A1 non-combustible. However, this does not mean that it will not burn in the event of a fire, it will only not contribute to the fire as it burns.
At The Loft Doctor, you can trust that we will only ever use safe, professional grade goods that are safe for you, your family, and your home.

Can loft insulation be too thick?

Yes, loft insulation that exceeds the maximum depth recommendations can create issues like damp and mould in your loft by affecting ventilation and causing condensation build up.
As well, if your insulation is too thick then you will likely be compressing it with your loft boards which will ruin its efficiency.

How long does loft insulation last?

Your loft insulation should last you at least 40 years. There are steps that you can take to make your insulation last longer, and things that you should avoid to keep it from needing to be replaced sooner.
By regularly inspecting your loft insulation every few months, you should be able to spot signs of damage or compression and then address it as you go. This will keep your loft insulation effective for as long as possible and it means that you will not have to completely replace your whole insulation layer if the damage spreads.
Common damage to loft insulation is compression. If you lay your loft boards directly on top of your insulation, then you will compress it and reduce its efficiency. Not only will it need to be replaced sooner, but it will be inefficient until it is replaced.

How to insulate an attic roof rafters?

You should only insulate your roof rafters if you plan to use your loft as a habitable space such as a bedroom.
If you only use your loft for storage, then insulating your roof rafters will be allowing heat to pass from your home into the loft where it is not needed.
However, if you use your loft as a bedroom (or plan to in the future) then insulating your roof rafters will be important to keep the room warm.
On inspection, our team at The Loft Doctor will consult with you on your goals for using your loft, and will be able to advise you on whether insulating your rafters would be a beneficial idea.

How much is loft insulation?

Loft insulation can cost anywhere from a few hundred pounds to a few thousand pounds, depending on the size and type of your house, the type of insulation used, and the labour involved.

We use quality materials that are still best value loft insulation so that we can pass the best cost onto our customers. Get in touch for a loft insulation quote.
