EPS 70

EPS 70 is a lightweight expanded polystyrene insulation board suitable for standard domestic loadings.

It delivers consistent thermal performance, helping buildings stay warmer in winter and cooler in summer while lowering energy costs.

Affordable, durable, and simple to work with, EPS 70 remains a go-to solution for efficient, modern insulation.

What Is EPS70 Polystyrene?

EPS 70 expanded polystyrene sheets are mostly used on floors, although they are also specified for wall and roofing applications.

“EPS 70” denotes the nominal compressive strength class – typically achieving around 70 kPa nominal compressive strength at 10% compression (EN 826). That number is the design indicator used when checking whether the board will accept the floor loading and screed type.

What Is Jablite EPS 70 Used For?

Often sold as Jabfloor 70, Jablite EPS 70 is ideal for solid or suspended ground floors, whether under screed, chipboard, or precast concrete slabs.

It works equally well below or above a slab, under timber or concrete floors, and even in loft or light storage areas where the load is modest.

Industry guidance and manufacturer literature consistently place EPS70 in the domestic/standard-loading bracket, where usage requirements are light to modest.

It is best used for:

• Domestic floor insulation (below screed or over slab for normal domestic loadings).
• Loft or roof board applications (accessible lofts, storage areas).
• General-purpose insulated fills and lightweight non-structural civil fill where moderate compressive strength is acceptable.
• Retrofits or renovations where speed and weight matter more than heavy-duty strength.
• Domestic roofing applications – can be used in lightweight roof and loft applications when part of a proper roofing system.

Benefits Of Expanded Polystyrene 70

Here are some advantages of using EPS70 polystyrene:

• Good compressive strength for domestic floors. EPS 70 handles standard household loadings comfortably – enough for screed, chipboard, plus daily foot traffic.
• Consistent thermal performance. Typical thermal conductivity is ~ 0.038 W/m·K. That gives a reliable insulation value across temperatures commonly found in buildings.
• Lightweight and easy to work with. Because EPS 70 is low-density and easy to cut or shape, it is a practical choice for on-site work or retrofit projects – less strenuous than heavier boards.
• Cost-effective and durable. As a closed-cell expanded polystyrene board, Jablite 70 remains stable over time, resists moisture ingress reasonably well when protected as part of a full system, and gives long-lasting insulation value with little maintenance.
• Versatility. Use Jablite EPS 70 in floors, under screeds, under chipboard, over concrete slabs – and even in lofts and suitable non-load-bearing wall systems. Its flexibility makes it a handy standard-grade board for many typical UK housing projects.

How to cut polystyrene 70?

EPS 70 is easy to cut on site using a fine-toothed saw or hot-wire cutter. Just ensure cuts are neat, edges flush, and boards tightly butted where necessary – especially when laying under screed or chipboard floors. Basic PPE, such as a dust mask, is recommended when cutting.

Can I use EPS70 for flooring?

Yes, EPS 70 is specifically designed for standard domestic flooring applications only; below-ground slabs, suspended floors, under screed or chipboard. EPS 70 handles standard loading like furniture and foot traffic well.
