webertherm XP dash system (EPS)

Name: webertherm XP dash system (EPS)
Brand: Weber

Replacement for: webertherm XP261

webertherm XP dash system (EPS) is a modern external wall insulation system which ideal for refurbishment projects to improve thermal performance and reduce interstitial condensation whilst providing the building with a durable dry dash finish.

This system uses expanded polystyrene insulation and is finished with a dry dash render finish which can be finished with a choice of decorative aggregates – ideal for areas of high water or weather exposure.

About this system

Our webertherm XP systems are specially designed using a mineral one coat render (webertherm M1) which doesn't require a base coat render. This means faster and more economical application, reducing labour and scaffolding costs. The disruption to the homeowner is minimised considerably.

Suitable for application onto masonry substrates, this system uses cost effective expanded polystyrene insulation (webertherm EPS) and is finished with webertherm M1 with an application of decorative aggregates for a durable dry dash finish.

Use multiple finishes on the same project

This system can be used in conjunction with the webertherm XP scraped system (EPS) for building designs which require a mix of dry dashed and render finishes.
