Sandtoft in-roof solar receives Environmental Product Declaration

Wienerberger UK & Ireland is pleased to announce that its seamless in-roof solar system now has Environmental Product Declaration (EPD) documentation available to download.

An Environmental Product Declaration, or EPD, is a document that discloses the environmental performance or impact of any product or substance across its lifetime in a transparent manner. An EPD is not a label or an environmental claim, and it does not necessarily mean that the product which has an EPD is environmentally better than the alternatives. The EPD does not say anything directly about the sustainability of the product.

An Environmental Product Declaration enables decision makers to understand the broad environmental impacts of a product, including the Global Warming Potential which indicates the contribution to climate change.

Customers are trying to understand the environmental impact of their product procurement decisions and a verified EPD is the best way to it.

Customers may also seek to specify a product with an Environmental Product Declaration to attract credits within the building assessment scheme BREEAM. 

Customers are often interested in the Global Warming Potential (GWP) indicator within an EPD, and in particular the result for modules A1-A3 which states the carbon impact of manufacturing product up to the factory gate. The GWP indicator describes the cumulative warming effect of seven greenhouse gases, i.e. the carbon impact of the product.

No, it does not. The function of an EPD is to provide information concerning a product's environmental impact; it does not state whether the product is a 'green' product or not. An EPD, on the other hand, can offer the necessary information that 'green' labels can then utilise to grant certificates.

It is not recommended that the data in EPDs from different manufacturers is compared, although we are aware that customers attempt to do this. This recommendation not to compare EPDs is made because, even though the EPDs may follow the same Product Category Rules and be third-party verified to ISO 15804, some variability in the results can occur due to several reasons. These include differences in the lifecycle assessment (LCA) data points modelled, the variance in the scenarios modelled, and the year the data was collected. 

Unlike traditional on-roof solar panels, which can look unsightly and out-of-place, a sleek and seamless in-roof solar system complements the roofscape.

Sandtoft in-roof solar is manufactured to SA8000 standard and BRE certified, offering simple installation that takes less than a minute per panel. Fitted directly to the roof battens, with no trays required, our solar panels are compatible with all Sandtoft and Keymer roof tiles and roof membranes. In addition to solar panels, we offer a range of batteries and inverters, for a complete solar roof solution.

Plus, our in-roof solar panels are covered by Sandtoft’s 15 year RoofSpec offering when incorporating the whole roof structure.*
