Application

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 a traditional roughcast render finish available in 23 popular colours.
