The Ultimate Guide To Loft Insulation

Installing loft insulation is the most effective way to increase the energy efficiency of your home, save on your energy bills and reduce your carbon footprint.

This guide to loft insulation will help you understand how it works, the materials you need and what you should consider before you start to insulate your loft!

Do I need loft insulation?

Put simply, yes. A home without loft insulation can lose a quarter of its heat through the roof.

The UK government’s recommendation for roof insulation is a minimum thickness of 270mm. Having insulation of this thickness can save you up to 25% on your energy and heating bills!

Insulating your loft is a great way to improve your energy performance certificate (EPC) rating in your home. As a result, it can increase the value of your home and reduce your carbon footprint.

How does loft insulation work?

The insulation in your loft works by trapping the warm air in your home and prevents it from rising through the roof. If installed correctly, it should allow moisture to pass through, helping to prevent condensation.

Incorrectly installed loft insulation can cause dampness and condensation in your home. Problems can arise if loft insulation is squashed by storage or if poorly installed loft flooring stops air flowing around the insulation.

If you’re looking to use your loft for storage, sufficient airflow is important. It is recommended to install a raised loft flooring to provide room for the full depth of insulation while creating a sturdy floor for your storage.

What materials should I use for my loft insulation?

There is a variety of types of loft insulation you can use. It is best to research which type fits the needs of your loft. For example, you can buy insulation in a range of stiffness, blanket rolls, sheets, wools and as loose-fill. Ensure whatever type you choose, that you install the recommended 270mm of insulation.

Each material comes with its own benefits and it depends on your loft environment as to which is best suited for you. Loft insulation can be effective for at least 40 years and should pay for itself many times!

What should I consider before you start?

Check the existing insulation in your loft

Many homes will already have insulation. However, you should check whether it reaches the minimum recommendation of 270mm. Some homes meet old recommendation standards so should be topped up to match current recommendations. For example, in 1995 the optimal depth was 200mm.

You should also check whether it is still fit for use. If the insulation is not providing optimal results, you should consider ‘topping up’ your insulation to the recommended depth. Or, replacing the insulation to give your home a well-needed insulation upgrade.

Storage Space

If you plan on using your loft for storage, you should ensure you have efficient loft insulation. This means having the recommended depth of 270mm insulation while providing a sufficient gap of airflow to prevent condensation.

This often creates an issue in homes as to get enough insulation, the loft flooring needs to be raised. Especially as boxes should not be placed on top of insulation as this stops the insulation from working effectively.

This is where LoftZone StoreFloor was created to solve this issue. StoreFloor is an award-winning, fully patented attic boarding system designed especially for installing a raised loft floor over insulation.
