How to insulate your loft

How to insulate your loft

Insulating your loft can seem like an unappealing job, but saving money on your utility bills always sounds good. If your home’s without loft insulation, you could be losing up to a quarter of your home’s heat through your roof*. This makes insulating your loft one of the most effective ways to reduce heating bills and be more energy-efficient. And even if you already have some existing insulation, it’s key to have the optimum amount for it to be truly effective.

In this guide, we’ll walk you through everything you need to know to lay loft floor insulation. Also known as ‘cold roof’ insulation, insulation is fitted to the floor of the loft trapping the heat in the main part of the house and away from the loft. This is ideal if you don’t use your loft at all, or only for the storage of non-perishable items.

The alternative is ceiling, or ‘warm roof’ insulation. This is fitted above the rafters and keeps the heat in the loft. It uses different types of insulation to loft floor and is used in loft conversions to make the space into a habitable living area. This isn’t explored in this article.

Our guide includes step-by-step advice on how to:

  • Work out how much existing loft floor insulation you already have
  • Confirm how much new insulation you need
  • Lay, and cut, two different types of loft floor insulation – rolls of insulation and insulated loft floor boards
  • Lay loft floor insulation around cables and recessed downlights.

Buying guides

Loft insulation buying guide

Loft insulation buying guide

Out of sight, out of mind – the dark, dirty loft is one of the areas of the house that can be neglected in favour of rooms that are more accessible and see more use. But, while insulating the loft is not one of the most glamorous jobs in the world, you should only have to do it once and it will prove massively beneficial to your comfort as well as your bank balance.

But before you head up into the loft, it’s important to decide which type of insulating material you’re going to use to complete the job. And where once there was very little choice available, now there are a number of different options to choose from – that can all be mixed and matched to suit your needs. So whether you’re looking for something that’s eco-friendly, that’s kind to the skin or even provides a stable surface for walking on – we’ll take you through all the different materials available.

Before you begin

It’s important to understand how much existing insulation your home currently has, and subsequently how much new insulation you need to complete your project. For more on this, read our guide on How to insulate your loft.

Don’t forget that loft floor insulation is compression packed for easier handling and will expand to the advertised thickness when unwrapped.

Rated 5 out of 5 by from Great product Bought this today in store after seeing it and thinking it would be ideal to use in the van to quieten the load area down. A lot of the rolls were wet when I went even though they are covered in the outdoor area. It’s great as it’s not itchy yet fills the sides of the van nicely. I did fold it over and one roll did the sides and rear door of my mk5 Astra van with about 300-400mm left. Would recommend it to anyone with a campervan etc as it’s warm in winter and cool in summer hopefully whilst keeping road noise down. Much cheaper alternative to the sound deadening stuff at auto shops.

Rated 5 out of 5 by from No gloves needed Bought this because it's a natural product, you don't have to worry about fibres, it's great to handle

Rated 5 out of 5 by from Fantastic product Needed loft insulation to cover existing dirty fibreglass insulation and went for this as it states say that you need to double layer it. I just used one layer on top of that. I tested that it was definitely flameproof too, as I was worried when someone said it could catch fire - Yes it is flameproof even though it is ecologically made from recycled plastic bags. I bought it when it was on special offer if you bought 4, then came back at paid full price for another 2 when the offer had gone (worth it in my opinion). It is narrower than I calculated. Like others say, it is easy to work with (I am an inexperienced old lady) - no itching. I started using a cutting tool but it soon became blunt. Eventually I found it easier to tear the product which is easier to mould into the shape required. I bunched it up and made it thicker than I had originally intended. I noticed the difference in the warmth immediately, the loft is cold while the bedrooms are so warm. It is a fantastic product. My only concern was that B&Q stored them outside, which meant I had to dry some of them out on a dry windy day before I could use them.

Rated 5 out of 5 by from Great product Delivered to house promptly and was easy to lay. Material was soft and pleasant to use. Have been away for a fortnight and flat seems to have kept warm so heating did not come on.
