When considering loft insulation for your home, safety is a top priority. One of the most common concerns homeowners have is whether loft insulation is flammable. In this blog, we’ll explore the flammability of different types of loft insulation, the safety standards they must meet, and why modern multifoil insulation is a safe and effective choice for your home.
Understanding Flammability in Loft Insulation
Flammability refers to how easily a material can catch fire and how it behaves when exposed to heat or flames. In the UK, all insulation materials must comply with strict fire safety regulations, ensuring they are safe for use in homes. However, the level of fire resistance varies depending on the type of insulation.
Flammability of Common Loft Insulation Types
Here’s a breakdown of how different types of loft insulation perform in terms of fire safety:
1. Mineral Wool (Glass Wool and Rock Wool)
- Fire Resistance: Mineral wool is non-combustible and highly fire-resistant. It can withstand temperatures over 1,000°C, making it one of the safest options for fire protection.
- Safety Note: While the material itself is fireproof, ensure it is installed correctly to avoid gaps that could allow fire to spread.
3. Natural Fibre Insulation (Sheep’s Wool, Hemp, etc.)
- Fire Resistance: Natural fibres are generally flammable but are often treated with fire retardants to improve their safety. However, they are not as fire-resistant as mineral wool or multifoil insulation.
- Safety Note: Regular inspections are recommended to ensure the fire retardant treatment remains effective over time.
2. Spray Foam Insulation
- Fire Resistance: Spray foam, particularly closed-cell foam, is flammable and can emit toxic fumes when exposed to fire. Some products are treated with fire retardants, but these only slow the spread of flames rather than prevent combustion.
- Safety Concerns: Improper installation or the use of untreated foam can pose significant fire risks. Additionally, spray foam can create ventilation issues, which may exacerbate fire hazards.
4. Multifoil Insulation
- Fire Resistance: Multifoil insulation, such as the products installed by LoftFoil, is designed with safety in mind. The aluminium foil layers are non-combustible and act as a radiant barrier, reflecting heat away from the home. Many multifoil products meet or exceed UK fire safety standards.
- Additional Benefits: Multifoil insulation not only offers excellent fire resistance but also prevents condensation and mould, which can compromise the safety and integrity of your loft space.
Fire Safety Standards for Loft Insulation
In the UK, loft insulation must comply with Part B of the Building Regulations, which governs fire safety in buildings. Insulation materials are tested for their reaction to fire and are classified under the European Standard EN 13501-1. The classifications range from A1 (non-combustible) to F (easily flammable). Always check the fire rating of the insulation you choose to ensure it meets the required standards.
Why Choose Multifoil Insulation?
Multifoil insulation is an excellent choice for homeowners who prioritise safety, energy efficiency, and durability. Here’s why:
- Fire Resistance: The aluminium layers are non-combustible, providing an added layer of protection in the event of a fire.
- Energy Efficiency: Multifoil insulation reflects up to 97% of radiant heat, keeping your home warm in winter and cool in summer.
- Durability: It is long-lasting, lightweight, and resistant to moisture, mould, and pests.
- Space-Saving: Its thin profile maximises usable loft space, making it ideal for modern homes.
