Silicone materials have a long history in high performance building projects. Known for durability, they can reduce a building’s carbon footprint by improving energy performance.
Historically, silicone materials’ performance attributes enabled 50 years of successful applications in structural silicone glazing and use as a thermal break in energy-efficient glazing. Looking to the future, silicone-powered technologies will influence improved energy performance via unique secondary sealant technologies and hybrid materials.
Leveraging past knowledge, looking at present research and envisioning future technologies, silicone materials will be a vital building block for innovation to achieve carbon neutrality in building performance.
Room-temperature-vulcanizing (RTV) sealants rely on moisture in the air to crosslink polymers into a cured rubber with a range of physical properties depending on the polymer backbone. Once crosslinked, these
An early use of silicone materials in construction was weathersealing horizontal glass tubes around the perimeter of a building located on the western shore of Lake Michigan in Climate Zone
Structural silicone glazing originated in the 1960s when a sealant was used to stiffen the connection between glass plates to an interior glass fin to give the appearance of an
Durability of silicone-based materials is derived from its molecular composition (Noll, 2012). The polymer backbone is comprised of alternating silicon and oxygen molecules, as shown in Figure 4. Like the
Hybrid sealants are formulated from combined chemistry sets of a different polymer backbone to a different reactive end to leverage the different performance characteristics of each (Klosowski, et. al., 2016)
Silicones have been a fundamental chemistry building block for high performance buildings for decades. Elasticity and weatherability enabled silicone-based materials to provide durable performance to manage air and water infiltration
