The B&Q EPS70 Polystyrene Insulation Board is an ideal solution for homeowners and professional contractors looking to enhance thermal efficiency in floors, walls, and roof spaces. Designed for durability and ease of installation, this rigid board helps reduce energy loss and maintain consistent indoor temperatures; however, users should note that as a 75mm thick product, it requires adequate clearance space in existing building cavities to ensure a proper fit.

While EPS is moisture resistant, it is not a vapor barrier. Ensure proper damp-proof membranes are installed according to building regulations.
A standard sharp hand saw or a hot-wire cutter is sufficient to achieve clean, accurate cuts.
Yes, it is often used as a base layer for underfloor heating systems to prevent heat from escaping into the sub-floor.
The EPS70 board has a compressive performance of 70kPa.
While generally safe, it is recommended to wear gloves and eye protection to prevent skin irritation from fine particles during the cutting process.
These boards are typically for internal thermal applications; check your local building codes for external wall insulation requirements.
Measure the gap carefully and trim the board using a fine-toothed saw to allow for a friction-fit.
Fill any gaps between boards with a compatible expanding foam to prevent thermal leakage.
Check the sub-floor for debris or irregularities; lift the board, level the surface, and relay.
Installation of the EPS70 board is straightforward but requires attention to detail. Ensure the surface area is clean, dry, and level before placement. When cutting, use a straight edge to guide your saw, ensuring the cuts are snug to avoid thermal bridging through gaps. Regarding compatibility, these boards are generally compatible with standard internal dry-lining systems and concrete floor slabs. Always store boards in a dry, covered area away from direct sunlight and heat sources. While the boards are durable, they should be protected from impact or heavy traffic before the final floor finish is installed to prevent indentations.
