Loft Insulation Dos and Don’ts

Loft Insulation Dos and Don’ts

Have you ever considered installing loft insulation in your home? Before making such an important decision, it’s a good idea to know exactly what benefits loft insulation can provide, and some of the most important loft insulation dos and don’ts as well.

Did you know that up to one-third of the heat you pump into your home from a fire or central heating could escape through your roof? This is not only bad news for the environment, it’s also costing you money in energy bills, and by installing loft insulation, you could save up to 20% on your energy bills every year.

So what exactly is loft insulation? Insulating materials are installed between the joists on your loft floor, effectively trapping heat in your home, and preventing it from escaping through the roof.

How Does Loft Insulation Reduce Heat Loss?

Loft insulation works by trapping heat below the loft space, thereby keeping the air in your property warmer for longer. It also helps prevent cold air from entering your property through the loft.

By reducing heat loss in this way, loft insulation can help you to save hundreds of pounds a year on your energy bills.

Now we know how loft insulation works to reduce heat loss from your property, it’s time to find out more about the specifics of loft insulation, as well as some loft insulation dos and don’ts. Let’s get started…

Loft Insulation Dos and Don’ts

Whichever method you chose, loft insulation will ultimately reduce heat loss through your roof, decreasing your energy bills and saving you money when it comes to heating your home

How Thick Should My Loft Insulation Be?

Generally speaking, the thicker the insulation, the better the performance when it comes to keeping your home warm. Imagine loft insulation like a winter coat – the thicker the coat, the warmer you will be. Using thicker materials as insulation helps to trap heat much more effectively.

There are two common methods used to apply loft insulation and we’ll cover both of them here:

The first method is ideal for hard-to-access lofts filled with nooks and crannies. As you can imagine, laying loft insulation in a tight or awkwardly shaped space can be a challenge.

Insulating foam can be blown into place using a hose and pressurised air, and it expands up to 100 times on impact, hardening to form a thick blanket of insulation, even in the tightest of spaces.

The other method commonly used to apply insulation is using batts (rolls) of fibreglass insulation. This type of application is ideal for regularly shaped loft spaces which are easy to access. The batts are simply rolled out and laid on the base of the loft.

Anybody considering carrying out home renovations needs to be aware of the government guidelines too, as they state that if you are planning to renew over 25% of your roof space, you must also ensure that your loft insulation meets the minimum values of the regulations

The Importance of Loft Insulation Thickness Regulations

So how do you know how thick your loft insulation needs to be? Luckily, there are regulations in place to help ensure that your insulation meets the minimum energy efficiency values, as outlined in the Government’s Approved Documents.

For most insulation projects, loft insulation should reach a recommended depth of 270mm. This figure can vary slightly, depending on the type of materials used – for example, the recommended depth for rock wool is 250mm, whilst for cellulose it’s just 220mm.

You might be tempted to ignore the regulations – but don’t be! By doing so, you could end up wasting money on fuel bills, as your loft could end up without adequate insulation, meaning you are completely wasting your time by installing insulation in the first place!

How Will You Know if You Need More?

Older properties will always benefit from additional loft insulation, and even properties over 10 years old may need upgrading to ensure you are saving money on your energy bills.

You might not be able to fully replace or upgrade your existing loft insulation, due to financial or space constraints, but it could still be possible to upgrade it to the best possible standard, reducing your energy bills, and making your home much more comfortable.

It is easy to check and see if you could benefit from upgrading or replacing your loft insulation. It’s a simple case of lifting the loft hatch and measuring the distance between the base board/element and the top of the insulation materials. For the best results, make sure you’re measuring at the lowest point.
