The comprehensive guide to loft insulation

We have written loads of blog posts about loft insulation over the years. Here we’ve gathered them together to give you a one stop guide and hopefully answer all the questions you may have!

Why should I insulate my roof space?

25% of heat in your home is lost through the roof. Clearly, this is a waste of energy and money. Loft insulation can be a good way to keep your home warm. Our tech pages can tell you more.

Which insulating material is the best?

Our favourite is sheep wool – it’s great because it’s 100% natural, controls humidity and you can do it yourself.

Other types include rigid boards, spray foam, mineral wool, polystyrene and fibreglass. We don’t really recommend fibreglass because there are other materials which have better insulating qualities without the health hazards!

Can I install insulation myself?

With some materials, yes! If you want to install the insulation yourself, you can find our guides here.

How much does insulation cost?

It really depends on which material you choose, and obviously how large the space is. Here’s a guide.

Here are some other questions we often get asked:

My roof is already insulated. Should I update it?

Can too much insulation cause overheating?

I’ve got a flat roof. Can it be insulated?

Will it mean I can’t store things up there any more?

You could also think about external wall insulation

As a side note, it is a little-known fact that even more heat (35-40%) is lost through the walls. This is why we’d always suggest you consider external wall insulation. It’s pricier, but considering the average home could save £300-400 per year on bills and some systems are guaranteed for a minimum of 25 years, it will probably pay for itself in the long run. It will also make your home a nicer place to be! Find more information here.
