• The Embodiment Of Lowering Embodied Carbon

Façade specialist Alsecco has introduced a low carbon basecoat for its external wall insulation to support sustainable building design through lowering embodied carbon in cladding systems.

 By switching to specially optimised cement that uses 30 per cent less carbon in the production process – Alsecco has launched a series of product upgrades to reduce the embodied CO2 in its adhesive and reinforcing compounds.

 An essential part of the fixing and finish of external wall insulation, the move follows the company’s commitment to source lower carbon façade solutions without compromising on performance.

 The highest levels of carbon within Alsecco adhesives and compounds comes from the cement elements used in the dry mortar.

 While the firing process for cement can be carbon intensive, it is the reduction of the raw materials to formulate the cement that generates further carbon emissions. By using lower clinker content, created with the raw materials, optimised cement is produced using less carbon.

 This, in turn, has allowed Alsecco to produce lower carbon adhesives. 

Net Zero

Ben Robinson, a technical manager at Alsecco, says: “Sustainability in the built environment is a priority in supporting global commitments to reach net zero by 2050.

“Alsecco is committed to supporting customers in creating more sustainable solutions wherever possible. In the construction industry it is important that any changes support the high standards in performance.

 “By looking to reduce the embodied carbon in our façade system adhesives, Alsecco is able to offer more sustainable solutions for building design, whilst ensuring high performance standards in external wall insulation systems and finishes.”

 Alsecco is in the process of converting all of its Armatop adhesives, as well as its laying mortar, and ceramic and glass adhesive products.
