Loft insulation – How can it save on heating bills?

TheEcoStore - Loft insulation

We have written an article previously on the importance of energy saving – it is a great way to lower your energy bills, but it also helps protect you against future price rises too, as well as all of the positive environmental influences it has.

The importance of loft insulation

In this blog we are going to look at loft insulation – often considered the best energy saving solution due to the relative low cost of installation and the energy savings it produces: specifically by avoiding wasted heat loss and consequently reducing your heating bills.

It is recommended, in building regs, that homes now have a layer of insulation 270 – 300mm thick in the loft space. If you don’t currently have anything in the loft space, installing insulation can lower your heating bills by as much as 35%. Obviously the actual heating savings will depend on how big the area of the loft space is, as well as the heating requirements of the house, but we have seen savings of over £300 per year on heating bills in some large properties due to better insulation in their lofts.

With the cost of materials only starting in the low £100’s, payback can be as a little as a year, so if you are planning on being in the house for longer, then it is a fantastic investment!

What products can you use?

There are lots of different products you can use to insulate your loft, including rigid insulating board and mineral wool insulation, natural Sheepwool, natural hemp insulation and finally, recycled plastic bottles insulation.

These materials offer not only fantastic insulating properties – in most cases better than alternatives – but they are all an absolute pleasure to work with. That sounds a bit of a funny comment when talking about insulation – but for those who have ever done the job with glass wool insulation – you’ll know exactly what we are talking about.

Glass / mineral wool insulation are just about the most itchy things on God’s green earth. The moment you handle them, your arms begin to itch, then your face, then it gets into your socks. It is just miserable!

Obviously you can mitigate this to some extend by using protective clothing, but the wool still has a habit of working its way through all the protection and making you itch!

If you have ever done the job though, probably worse than the itching is what you are breathing in. The black stuff that comes out of your nose a day later – this stuff can’t be good for you! While there aren’t any links to suggest that it causes long term detrimental effects to your lungs – why take the risk!

So yes – even if you ignore the environmental credentials of our ‘greener’ insulation products – wool-based products are much easier to use and get the job done. It means going into the loft at a later date isn’t going to be that traumatic experience either.
