Foil Loft Insulation
Why Foil Insulation?
Choosing the right loft insulation can make a real difference to your home’s comfort, running costs, and even its value. Foil loft insulation, like YBS Superquilt and SuperFoil SF19+, stands out for several reasons.
Unlike traditional materials, foil insulation reflects heat (up to 97%), helping to keep your home warm in winter and cool in summer, all while taking up less space. It also acts as a vapour control layer, which is a big advantage in the UK’s damp climate.
By upgrading from traditional insulation laid on the attic floor to a modern warm loft system, you transform your loft from what’s known as a “cold loft” to a “warm loft.” In a cold loft system, insulation is placed only between the joists on the floor of the attic, which means the loft space itself remains unheated and is often subject to significant temperature fluctuations. This can lead to cold surfaces within the loft, increasing the risk of condensation as warm, moist air from the living areas below rises and meets the colder air in the loft.
As SuperFoil Approved Installers, we expertly install advanced foil insulation that stops moisture from building up, helping prevent black mould—a common problem with older types of insulation. Black mould isn’t just unpleasant; it can also affect your health and lead to legal issues, as landlords are required by law to deal with dampness and mould under the Homes (Fitness for Human Habitation) Act 2018.
Another important point is the trouble many people face with spray foam insulation. While it might seem like a quick fix, spray foam can actually make it harder to sell your home or get a mortgage. Surveyors often flag spray foam as a risk, and some lenders simply won’t offer mortgages on properties where it’s been used. This can cause real problems for both sellers and buyers.
That’s why more homeowners are choosing foil loft insulation. With trusted products like YBS Superquilt and SuperFoil SF19+, you get excellent thermal performance, protection against damp, and peace of mind when it comes to selling or remortgaging your home. It’s a smart, future-proof investment for any property.

Key Benefits of Foil Insulation
Removing spray foam insulation is a complex and labour-intensive process that requires expertise and specialised equipment. At LoftFoil, we follow a meticulous approach to ensure safe and thorough removal:
Superior Thermal Performance
Foil insulation reflects up to 95% of radiant heat, making it highly effective in reducing heat loss through your roof.
Space-Saving Design
Its slim profile means it takes up less space compared to traditional insulation materials like mineral wool, making it ideal for homes with limited loft space.
Year-Round Comfort
Keeps your home warm in winter and cool in summer by regulating temperature more effectively.
Eco-Friendly
Many foil insulation products are made from recyclable materials, contributing to a more sustainable home.

How Does Foil Insulation Work?
Foil insulation works by reflecting radiant heat rather than absorbing it. It consists of layers of reflective aluminium foil combined with insulating materials such as foam or air pockets. This design creates a barrier that prevents heat transfer, keeping your home energy-efficient and comfortable.
Our Foil Insulation Installation Process
Installing foil insulation is a straightforward process when done by professionals. Here’s what to expect:
Assessment
A thorough inspection of your loft space to determine the best approach.
Preparation
Clearing the loft area and ensuring it is clean and dry.
Installation
The foil insulation is carefully laid or fixed to the roof joists, ensuring a snug fit to maximise efficiency.
Sealing
Edges and joints are sealed to prevent air leakage and ensure optimal performance.

Frequently Asked Questions
What is foil loft insulation and how does it work?
Foil loft insulation is a multi-layered material that reflects heat back into your home, helping to keep it warmer in winter and cooler in summer. Unlike traditional insulation, it works by reflecting radiant energy as well as providing a thermal barrier.
What are the benefits of foil loft insulation compared to traditional options?
Foil insulation is thinner and lighter than traditional materials, yet offers excellent thermal performance. It also acts as a vapour control layer, helping to prevent condensation and black mould, and maximises usable loft space.
Is foil loft insulation suitable for all types of properties?
Yes, our foil insulation products, including YBS Superquilt and SuperFoil SF19+, are suitable for most property types—whether you have a modern home, a period property, or are undertaking a renovation or new build.
Will foil loft insulation help reduce my energy bills?
Absolutely. By improving your home’s thermal efficiency, foil loft insulation helps to reduce heat loss, meaning you’ll use less energy to keep your home comfortable, which can lead to noticeable savings on your energy bills.
Is foil loft insulation compliant with UK building regulations?
All the foil insulation products we install at LoftFoil, such as YBS Superquilt and SuperFoil SF19+, are fully certified and meet UK building regulations for thermal performance and safety.
How long does foil loft insulation last?
Foil loft insulation comes with a lifetime guarantee, so you can be confident it will perform year after year without sagging or losing effectiveness. Once installed, it needs virtually no maintenance, offering you complete peace of mind for as long as you own your home.
Have you noticed signs of damp in your home?
Many people don’t realise that problems often start in the loft — an area that’s out of sight and out of mind. In traditional cold lofts, warm air from your home meets the cold surfaces in the loft, leading to condensation. Over time, this constant moisture can soak into the wooden beams, causing serious problems like dry rot, wet rot, and even structural damage to your roof.
The National House Building Council (NHBC) advises that when timber moisture content rises above 20%, it enters the decay zone, where conditions are ideal for serious problems like dry rot and wet rot to develop, leading to structural damage if left untreated.
It’s not just the beams at risk — damp conditions also cause mould to grow on your existing insulation. This reduces its effectiveness, creates unpleasant smells, and can lead to health concerns, especially for those with breathing difficulties. If left untreated, these problems only get worse over time, becoming much more costly to put right.
LoftFoil in Action
To give homeowners a clearer picture of what’s involved in a full loft transformation, we’ve produced a short video showcasing our team at work. The film follows projects just like this one in Malvern, from the careful removal of old, moisture‑laden fibreglass through to the installation of fresh loft roll and SF19 multi-foil insulation on the underside of the roof.
Watching the video, you’ll see:
- How we protect your home and safely handle and remove old materials
- The clean, methodical way our installers prepare and insulate the loft space
- The bright, reflective finish of the new foil insulation that helps stabilise temperatures and reduce future condensation
This footage helps demonstrate the standard of workmanship our customers can expect on every LoftFoil installation, and shows exactly how we turn a damp, inefficient loft into a clean, high‑performance space designed to last for decades.
How Loftfoil Helps Protect Your Home
Loftfoil stops cold air from reaching your loft space and locks warm air inside your home. By preventing condensation, it protects your roof, beams, and insulation from damp and damage.
Over time, traditional insulation can lose its thermal efficiency due to moisture absorption, sagging, or degradation, resulting in higher energy bills and costly replacements. For homeowners seeking a safer and more reliable alternative, SuperFOIL insulation offers a superior solution that avoids these common issues.
