Roundtable: Thermal Barriers in Retrofit

摘要

MCN: What are the differences between ther-mal barriers for building retrofit vs. thermal barriers in new construction? Dan Harkins: "Thermal barriers" are defined for the purposes of this roundtable as "insulation systems" that inhibit the transfer of heat energy through the building envelope, roof and/or wall assemblies. Whether for new construction or retrofit applications, the basic requirements of insulation systems are generally the same, although in retrofit applications there may already be thermal breaks, air barriers and existing insulation, which are typically left in place and added to.
