EPS (Expanded Polystyrene) is a lightweight and rigid insulation material common in UK construction. This type of insulation can be supplied as boards or beads and is valued for being reliable, easy to work with and good value for money. EPS is made by expanding polystyrene beads using heat, creating a closed-cell structure that traps air. This trapped air provides the insulation performance.
Where is EPS insulation commonly used?
EPS insulation is suitable for a wide range of home improvement and building projects. Common applications include:
- Cavity Wall Insulation (Bonded Bead for full fill and partial fill applications)
- Floor insulation
- Insulated Foundation Systems
- Loft and Roof Insulation
- Pipe Insulation
- External Wall Insulation
Why choose EPS insulation?
EPS offers long-lasting performance and is designed to remain effective. Once installed, it doesn't shrink or break down, meaning reliability and consistency. EPS is also resistant to moisture and rot, so it's a versatile choice for floors and areas where damp resistance is important.
For many DIY projects, EPS is a cost-effective insulation choice thanks to its reliable thermal performance at a lower price point than some high-performance alternatives. EPS is also considered fairly easy to handle and install for the average DIY-er
Is EPS right for your project?
EPS insulation is a practical choice if you're looking reliable performance, moisture resistance, straightforward installation and good value for money. Whether you’re retrofitting an existing building or planning a new build, EPS can help you achieve your low-energy goals at a reasonable cost.
