As cited in Mansion Global
(September 24, 2023), barn cover metal-skinned referred to as
barndominiums (“barndos” for short) have exploded in recent years. As of
mid-September, there were roughly 4,000 active U.S. listings that
advertised being or having a barndominium, a 26 percent increase from
the same time a year ago, according to data Realtor.com. This article
will discuss performance issues and spray polyurethane foam insulation
product choices, which impact the long-term performance of the building
envelope.
One of the primary purposes of Insulation systems and
materials, designated as the “thermal control layer,” is to reduce the
potential for condensation forming within the building envelope that may
lead to reduced structural integrity and unhealthy indoor air quality.
The type of insulation, interior environment, exterior environment and
need for additional control layers play an important role in the
effectiveness of the insulation chosen. The more familiar purpose is to
reduce heat flow through envelope assemblies resulting in reduced energy
consumption and a more comfortable occupied space.
