At Key Loft Storage, our loft insulation installers provide an effective thermal barrier between your home and the outside extremes. This helps prevent heat loss and can lead to significant savings on your energy bills. But which type of insulation is the best for your needs?
We recommend Earthwool insulation, available in various depths. It is a cost-effective, eco-friendly option made from recycled materials, making it non-combustible. Unlike traditional insulation, Earthwool offers a soft feel without the itchiness. While Earthwool is a great choice, there are several types of loft insulation to consider.
Different Types of Loft Insulation
The recommended depths for loft insulation are 270mm for glass wool, 250mm for rock wool, and 220mm for cellulose.
-
Blanket Insulation
Blanket insulation is the most common form, available in rolls of rock, glass, or mineral fibre. It is typically the cheapest option and works well between timber joists in the loft. This type is easy to install yourself without professional help.
-
Sheet Insulation
Sheet insulation consists of firm boards made from synthetic or natural materials. Best for insulating the underside of your roof, it allows for internal decoration. While effective, this option can be more expensive.
-
Blown Insulation
Blown insulation is installed using a machine, making it suitable for hard-to-reach areas. This method requires professional installation and is often used to supplement existing insulation.
-
Loose-fill Insulation
This insulation comprises a mixture of lightweight materials, such as cork granules and cellulose fibre. It can be used alone or to enhance existing insulation. However, it can be messy and is less secure than other options.
-
Spray Foam
Spray foam insulation expands upon application, helping to retain heat and reduce energy costs. It can also provide additional soundproofing. Due to its specialist installation requirements, it tends to be a more expensive choice. Consider its appearance and whether you will use the loft functionally before opting for this method.
Which is the Best Type of Insulation?
Choosing the most effective insulation depends on your intended use. If you plan to use your loft as a functional space, opt for a more visually appealing option that minimises mess and allows for decoration. For maximum heat retention, select insulation designed to prevent heat loss effectively.
How to Look After Your Insulation
Regularly assessing your insulation is essential to ensure it was installed correctly and remains effective. Measure the depth of your existing insulation to check if it meets standards. If it doesn’t, Key Loft Storage offers experienced installers who can relay it correctly, placing one layer between the joists and another layer across them. This ensures compliance with building regulations.
Investing in a raised loft boarding system designed for insulation is also crucial. Key Loft Storage innovative loft installations raise boarding from the joists, preventing compression and ensuring optimal performance. This approach extends the lifespan of your insulation, eliminating the need for frequent replacements.
