Building energy codes continue to shift in the direction of increased energy efficiency, resulting in tighter and better insulated buildings. At the same time, a focus on indoor air quality (IAQ) in the built environment is gaining traction. One way to counteract the negative effects of potentially toxic building materials on the occupants of a space is to choose insulation that ‘breathes,’ such as wool insulation.
When the National Football League (NFL) announced its 52nd championship game would take place in Minneapolis, Minnesota, professionals in hospitality, commercial real estate, and construction industries in the Twin Cities scrambled to capitalize on the future economic infusion from the big game, slated for February 4.
Pressure-sensitive adhesive (PSA) tape technologies have properties that can insulate a building from environmental events such as precipitation, vapor ingress, extreme cold and heat, and external noise. While there may be a temptation to use putties and caulks instead of PSA tapes for insulation purposes, those materials are typically employed as fillers meant to span gaps—they do not provide an air or water barrier. PSA tapes can be used as an effective alternative or complementary barrier throughout a building by sealing areas like windows and doors that may be vulnerable to outside environmental fluctuations.
Hundreds of years ago, buildings were thought of much more simply—as shelter, meant to protect people from the elements. Today, that purpose holds, but the technology, practices, and materials that go into high-performing building enclosures have evolved to do more.
A masonry cavity wall system must successfully perform multiple functions throughout the life of the building. A proper wall is expected to manage moisture, air, and heat, contain fire, and hold up the structure itself.
