Jablite EWI EPS 70 HPE+ 50mm 1200mmx600mm

The Jablite EWI HP+ 50mm insulation board is made from expanded polystyrene (EPS) and is designed for use in suitable external wall insulation (EWI) systems. Its slim 50mm profile is an option for projects where space is limited and a thinner insulation layer is required, provided it meets the building’s thermal performance requirements.

These lightweight EPS boards can be bonded or mechanically fixed to suitable external walls as part of an approved insulation system. Depending on the system specification, compatible finishes may include reinforced render, tile hanging, timber weatherboarding or plastic weatherboarding. Always follow the system manufacturer’s installation and fixing instructions.

Benefits of Jablite EPS External Wall Insulation

Lightweight and practical to install

EPS insulation boards are lightweight and can be cut to size with suitable tools, helping installers work around the dimensions and details of a project.

Suitable for compatible EWI systems

These boards are designed for use with compatible external wall insulation boards and approved fixing systems, helping create a suitable base for rendered façades.

Durable insulation material

Jablite EWI HP+ is described as rot-proof and durable. When installed correctly within a suitable system, it is intended to provide long-term insulation performance.

Render and cladding options

Depending on the approved system design, EPS insulation may be used behind reinforced render or compatible cladding finishes. Check the system specification before selecting materials.

Durability and Flood Resistance

The manufacturer’s product information describes Jablite EWI HP+ as durable, rot-proof and flood-resistant. Performance depends on the product, installation and surrounding wall construction, so consult the current technical documentation for the applicable conditions and limitations.

Fire Safety and Building Regulations

The fire performance of an external wall insulation assembly depends on the insulation, finishes, fixings, building design and intended application. Check the current UK Building Regulations, relevant fire-safety requirements and the system manufacturer’s guidance before specifying the product.

Water Vapour and Condensation

EPS insulation offers resistance to water vapour but should not automatically be treated as a vapour-control layer. Condensation risk depends on the complete wall build-up and environmental conditions. Seek an appropriate condensation assessment where required for the project.
