Carbon-neutral silicones for building façades: A global, project-specific service

First-ever carbon-neutral silicones for façades verified by PAS 2060 standard for carbon neutrality

noav-content-carbon-neutral-silicones-graphic-788x272

Address key application requirements on façades; request carbon neutrality certificates for specific projects

PAS 2060 verified carbon neutrality icon

Benefit from the world’s first commercially available project-specific carbon-neutral silicones for building façade applications. Dow Building Science has a strong commitment to reduce our carbon footprint and help address climate change. With more than 50 years of innovation and global leadership in structural silicone glazing, Dow is the first to offer high-performance bonding silicones with externally verified carbon neutrality. Related carbon neutrality certificates can be requested with the service offered on a project-by-project basis globally.

Dow’s service theme, “Building with more freedom by engineering less impact,” will underscore how our carbon-neutral silicones for bonding and structural glazing can help reduce the environmental impact of buildings, achieve better green-building certification ratings and help limit the creation of greenhouse gases (GHGs) that contribute to earth’s climate changes.

  • Global offer – project-specific Dow carbon neutrality certificates
  • Trusted & credible – PAS 2060; externally verified
  • Supports earning additional green-building credits
  • Enhance carbon balance (>20x) with long-term durable façade silicones
  • Design with less embodied carbon – potential aluminum reduction up to 15% in structural glazing façades
  • Enhance operational carbon reduction – explore energy efficiency gains of up to 10% with structural glazing designs

Leading the way in decreasing the embodied carbon in construction materials, Dow will support our carbon-neutral silicones with Verified Carbon Neutrality Certificates, Environmental Product Declarations (EPDs) and comprehensive Life Cycle Analysis (LCA) data.


Carbon-neutral DOWSIL™ Brand Façade Silicones – with Dow’s own generated carbon insets

noav-content-equation-carbon-neutral-788x368

Carbon footprint reduction of silicon metal

  • Silicon metal production is the biggest contributor to carbon emissions in the process of producing silicones.
  • Significant reduction of carbon emissions from 60-85% have been achieved just by focusing on energy consumption and raw materials.

Dow’s carbon sinks used as carbon insets

Dow is using its own eucalyptus plantation and reforestation process to help ensure long-term carbon capture capabilities. The faster-growing eucalyptus trees can be regenerated in seven years, offering carbon sinks and raw materials (wood chips and charcoal) for silicon metal production.

Environmental, Social and Governance (ESG) efforts focus not only on product

Greenhouse gas emissions – of which carbon dioxide emissions are the biggest contributors – accelerate global warming. It is not enough to focus only on the emitted carbon during the production of materials. It is important to acknowledge that this has an impact on environmental, social and governance aspects. Dow is building significant social capital in local communities with various work, educational and healthcare programs. Learn more in the 2021 Dow ESG report.


Dow’s fully backward-integrated silicone production capabilities not only help ensure precise control over the entire value-chain process and quality, but they also enable key achievements contributing to DOWSIL™ Brand Carbon-Neutral Façade Silicones and their carbon footprint verified under PAS 2060.

Back-integrated silicone manufacturing

Dow Building Science and the ‘carbon journey’

A holistic view of carbon neutrality is important beyond looking at the footprint of carbon-neutral DOWSIL™ Brand Façade Silicones. Equally important is considering the handprint and blueprint.
 

The handprint: DOWSIL™ Brand Façade Silicones have excellent long-term durability, with applications exceeding 65 years for weather sealants and more than 50 years for four-sided structural glazing silicones. Hence, the ratio between the carbon emitted during silicone production and the carbon emissions saved thanks to silicone’s longevity is very high. A factor of more than 20 has been calculated for insulating glass, as an example.

The blueprint design advantage: Looking beyond, think about the façade design. Silicones contribute to the realization of high-performing structural glazing façades with pure glass aesthetics. Can their use further decrease embodied carbon of the façade or contribute to a reduction of carbon emissions during building operation compared to captive façade designs, for example?
With the global diversity of façade designs and systems, the design technique can have a significant influence on the blueprint.

  • Design with less embodied carbon: Structural glazing designs can help save up to 15% of needed aluminum, leading to a reduction of the overall embodied carbon of a façade.
  • Energy efficiency: Simulations have shown that specific structural glazing designs can contribute to a reduction of the curtainwall U-value (UCW) of 10-25%, depending on the region and type of façade system.

Enhance your footprint, handprint and blueprint with DOWSIL™ Brand Façade Silicones.
