EXTERNAL ENVELOPE
Senior opens the door (and window) to greater transparency with new EPD releases
S
Architectural Systems has expanded its suite of independently verifi ed Environmental Product Declarations (EPDs) to give architects and contractors even greater confi dence and clarity when assessing the environmental impact of some of the manufacturer’s most popular fenestration systems.
enior Following the publication of the EPD for
its SF52 mullion drained curtain wall, Senior has now released new declarations for its PURe®
Commercial Door, PURe® and PURe® Casement
Tilt & Turn aluminium windows, plus the zone drained version of its SF52 curtain wall system.
Senior has been keen to challenge the traditional format of EPDs, and specifi cally those for aluminium fenestration systems, which has been underpinned by the company’s pledge to customers that ‘what you see is what you spec’.
The new publications continue Senior’s commitment to providing transparent, specifi cation-ready
data that refl ects the
true performance of the fenestration systems being designed into a project and each new EPD follows the same methodology that set the SF52 mullion drained curtain wall EPD apart. By removing insulated glass units from the calculations, the data focuses solely on the aluminium system itself. This prevents artifi cially low carbon fi gures and gives a more accurate representation of the product’s impact per square metre.
Architects and contractors working across a range of building types also benefi t from the non-linear scaling approach used throughout Senior’s suite of EPDs. Instead of relying on a single reference size, multiple system sizes for each product have been independently verifi ed and consolidated into one document. This allows for more precise modelling at the early design stages and supports more robust comparisons between facade options.
Another key way that Senior is taking a different approach is by ensuring the new EPDs all include the environmental impact of profi le extrusion and non-aluminium components such as thermal breaks, gaskets and fi xings. These elements are often excluded from conventional EPDs, yet they can signifi cantly infl uence the overall footprint of a facade system. Their
inclusion gives architects and contractors a more complete picture of the materials they are specifying and supports more accurate whole-building assessments. The PURe®
Casement window and PURe®
Commercial Door, PURe® Tilt &
Turn window systems all feature Senior’s patented expanded polyurethane thermal break, delivering high thermal performance without compromising design fl exibility. The new EPDs provide verifi ed data that further supports the proven thermal performance of the PURe®
system which has the potential to deliver low U-values that exceed current building regulations.
Commenting on the publication of the company’s new Environmental Product Declarations (EPDs), Senior’s UK sustainability lead Luke Osborne said: “The expansion of our EPD portfolio refl ects Senior’s long-term commitment to responsible manufacturing and meaningful sustainability reporting. Our latest EPDs give the level of clarity and detail we know our customers are looking for to make informed
decisions at concept stage and throughout the specifi cation process. By including all product elements as part of our EPDs we’re able to produce much more accurate data and I’m proud that this approach makes them deliberately different to other EPDs for comparable systems.
“Our commitment to providing greater transparency is matched by our desire to help specifi ers to better understand the complex information presented in the EPDs. We are always on hand to answer any questions that any of our customers may have to ensure that our EPDs truly are a helpful and reliable resource.” All new EPDs are available to download via Senior’s NBS Source profi le or directly from the company’s sustainability team.
