A breakthrough monocouche render using increased levels of recycled material is now available to help housebuilders achieve sustainability targets.
weberpral E by Saint-Gobain Weber uses the next generation of cement replacement, resulting in a 22%* reduction in carbon emissions from fossil fuels and by 10% overall compared to its current monocouche. The render also cuts non-renewable energy consumption by 19%*, uses 28%* less water in the raw material supply and saves 25%* energy consumption in total over the lifecycle of the product.
With many renders requiring 20mm thickness in locations classed as ‘severe exposure’ to combat high levels of wind-driven rain and frost, weberpral E has reduced water absorption so can be applied at just 15mm thickness to achieve the same performance. This means around 25% less material is needed.
James Mead, R&D Director, Saint-Gobain Weber said:
“Our customers are increasingly turning to us to help them achieve their ambitious sustainability targets. We’ve worked with a panel of professional renderers across the UK to help develop and test weberpral E to make sure it’s not only more sustainable than previous renders but that it carries the same industry-leading standard of performance.
“Blind tests, including spraying, ruling, and scraping, were carried out with four other leading monocouche renders with weberpral E coming out on top, in each category including ease of application. Essentially weberpral E boasts all the same key features as our original monocouche render but is demonstrably better for the environment.”
To reduce the reliance on using traditional cement, many of Weber products use cement replacement technology. However, the new approach for weberpral E introduces a more sustainable alternative resource.
An Environmental Product Declaration (EPD) is also available for weberpral E, making it and weberpral M and D the only monocouche renders in the market to carry the Type III environmental label.
James added:
“Having an EPD in place for weberpral E was a vital step for us, as we can offer the sector verified information on cradle-to-grave environmental performance, while giving our customers information that helps them decarbonise and reduce their own environmental footprint.”
Weber is part of the Saint-Gobain group which has a target to become carbon net zero by 2050.
