Effective loft insulation is not only good for reducing your carbon footprint, but it can also help you save up to 20% on your electricity bills. There are several things to consider before updating or adding insulation to your residence, so here is a definitive guide that will help you find the best loft insulation for your property.
How to choose the best loft insulation?
- Warm or cold loft
If you have a typical house with a sloped roof, you will need to decide between a warm and a cold loft. These terms can often be misleading, as warm lofts remain cool in the summers. Cold lofts (insulation only directly above the ceiling between and over the joists) are cheaper and better suited if you only intend to use your loft for general storage. Warm lofts (insulation just under the roof and in the rafters) is better suited if you want to use your attic for your hobbies, or store temperature-sensitive items.
- Types of loft insulation
The most common type of loft insulation is blanket insulation, where rolls of rock, glass, or mineral fibre are used to insulate the joists. For roof undersides, sheet insulation is usually preferred, where firm boards of synthetic or non-synthetic materials are used for insulating the loft. For topping up existing insulation, loose-fill insulation is used, where lightweight materials like cork, cellulose, or mineral wool are used. The most effective one is spray insulation, which can be used anywhere in the house and provides excellent heat efficiency throughout the year.
- Insulation depth
Depending on where you reside, there can be a recommended insulation depth that you will need to confirm from the authorities beforehand. Usually, newer properties require up to 300mm insulation depth, which can go higher if your house feels colder. Unless the property is a new build, it is worth checking the insulation before purchase and every following year, as it may be time for a top-up. If the house is an older one (built before 1995), it is highly likely that it won’t meet the existing insulation requirements.
