Thermal bridges are highly conductive structural elements that create heat transfer between the exterior and interior of the building thermal envelope. Thermal bridging occurs through any material that is more conductive than the insulation surrounding it. The conductive heat transfer due to thermal bridging has been recognized as a considerable factor in building envelope heat loss.
Thermal bridging through steel and concrete structures can therefore have a signiﬁcant impact on a building’s energy performance. Thermal bridging can reduce the R value of a wall assembly by as much as 50% by interrupting continuous insulation. Reducing heat ﬂow through a building’s thermal envelope reduces energy consumption as well as potential condensation issues. To achieve higher R values, thermal bridging and air leakage must be minimized.
As early as 2006, many European countries had already instituted improved energy rating systems for new buildings to better control and reduce domestic energy consumption. Nearly 10 years ago, in response to an EU initiative to improve the energy performance of buildings even further, Armadillo Ltd. developed its ﬁrst thermal break material, Armatherm™ to prevent heat loss due to thermal bridging.
Since 2011, drawing on Armadillo Ltd.’s experience, Armatherm™ has been working with architects and structural engineers in North America to improve building design details and reduce heat loss due to thermal bridging within the building thermal envelope.

- U.S. GREEN BUILDING COUNCIL
The U.S. Green Building Council (USGBC) is committed to transforming the way our buildings are designed, constructed and operated through LEED — the top third-party veriﬁcation system for sustainable structures around the world.
RCI, Inc. is an international nonproﬁt association of professionals who specialize in rooﬁng, waterprooﬁng, and exterior wall speciﬁcation and design. From sprayed polyurethane foam to cedar shakes, from parking garages to air barriers, RCI has a member expert for every type of roof, exterior wall, or waterprooﬁng issue in the world today.
The American Institute of Steel Construction (AISC), headquartered in Chicago, is a not-for-proﬁt technical institute and trade association established in 1921 to serve the structural steel design community and construction industry in the United States.
The National Institute of Building Sciences was authorized by the U.S. Congress in the Housing and Community Development Act of 1974, Public Law 93-383. In establishing the Institute, Congress recognized the need for an organization that could serve as an interface between government and the private sector.
