Loft Floor Insulation Installation
Why Insulate Your Loft's Floor?
Did you know that up to 25% of your home’s heat can escape through an uninsulated loft? Insulating your loft floor is one of the most effective ways to improve your home’s energy efficiency. By creating a thermal barrier, you can prevent heat from escaping in the winter and keep your home cooler in the summer.
Loft floor insulation is particularly beneficial if you’re not using your loft as a living space, as it focuses on insulating the areas that matter most—your home’s living areas. It’s a cost-effective solution that delivers long-term savings on your energy bills while reducing your carbon footprint.
What Type Of Insulation We Use
At LoftFoil, we use two main types of insulation for loft floors:
Rockwool Insulation
Rockwool insulation is made from natural stone fibres and is widely regarded as one of the most effective materials for loft floor insulation. It provides exceptional heat retention, helping to keep your home warm during the colder months and cool in the summer. In addition to its thermal efficiency, Rockwool is also highly effective at soundproofing, as its dense structure absorbs noise, making your home quieter and more peaceful.
Fibreglass Insulation
Fibreglass insulation, on the other hand, is a lightweight and cost-effective solution that is also highly effective at reducing heat loss. Made from fine glass fibres, it traps air to create a thermal barrier that improves your home’s energy efficiency and helps lower heating bills. Fibreglass is an economical choice, making it ideal for homeowners who want reliable insulation on a budget. Its lightweight nature also makes it easy to install, ensuring a quick and efficient process.
For Loft Roof Insulation, we use Foil Insulation. See our Foil Loft Insulation Page for more.

Frequently Asked Questions
How much does loft floor insulation cost?
The cost of loft floor insulation depends on the size of your loft and the type of insulation used. At LoftFoil, we provide bespoke quotes tailored to your specific needs. Contact us today for a free estimate.
How long does it take to insulate a loft floor?
Most loft floor insulation projects can be completed within a day, depending on the size and complexity of the space. Our team works efficiently to minimise disruption to your home.
Can I insulate my loft floor myself?
While DIY insulation is possible, professional installation ensures the job is done correctly and safely. Our team has the expertise to install insulation effectively, maximising its performance and longevity.
What’s the difference between loft floor and loft roof insulation?
Loft floor insulation focuses on creating a thermal barrier between your living space and the loft, while loft roof insulation is designed to insulate the roof itself. If you’re using your loft as a living space, roof insulation may be a better option.
Is Rockwool or fibreglass better for loft floor insulation?
Both materials are excellent choices, but the best option depends on your specific needs. Rockwool offers superior soundproofing and fire resistance, while fibreglass is lightweight and cost-effective. Our team can help you decide which is right for your home.
Does loft floor insulation help with condensation?
Yes, loft floor insulation can help reduce condensation in your home. By creating a thermal barrier, it prevents warm air from rising and meeting the cooler surfaces of your loft, which is a common cause of condensation. Proper insulation, combined with good ventilation, helps maintain a balanced temperature and reduces the risk of damp or mould forming in your loft space.
