Expanded Polystyrene (EPS)

Expanded polystryrene insulation is used as part of a Wetherby External Wall Insulation system to provide an efficient and cost-effective solution. Its closed-cell structure inhibits water absorption and it is unaffected by the normal range of climatic conditions.

Wetherby offer a range of Expanded Polystyrene Insulation options depending on your project requirements.

Enhanced EPS Insulation

Wetherby’s Enhanced EPS Insulation comprises of expanded beads of polystyrene that incorporate a graphite component, fused together in a pressurised steam-heated mould. The addition of graphite provides a significantly improved thermal insulation material.

Wetherby’s Enhanced EPS Insulation is produced to the requirements of ‘BS EN 13163 Thermal Insulation
Products for Buildings – Factory Made Products of Expanded Polystyrene (EPS)’ specification.

High Density EPS Insulation

The unique tongue and groove interlocking configuration is designed on larger high density EPS insulation boards (1200mm x 1200mm).

This significantly reduces boarding installation times while offering superior strength, high levels of impact resistance and protection against water ingress.

Available with a ribbed surface for brick slips or without for render.

Expanded EPS Insulation

Expanded Polystyrene (EPS), often referred to as Styrofoam, is made from polymer impregnated with a foaming agent which, when exposed to steam, creates a uniform closed cell structure highly resistant to heat flow and moisture penetration.

Expanded Polystyrene is one of the least expensive, most cost effective rigid foamed plastic insulations and is an excellent material for wall insulation applications that come with a restricted budget.
