Commercial R-Value Requirements by Climate Zone (ASHRAE 90.1)
Quick answer: ASHRAE 90.1 sets minimum R-values for walls, roofs, and floors in each of its eight climate zones, with separate targets for continuous insulation and cavity insulation. For most […]
Thermal Window Framing: How Windows Quietly Undermine Continuous Insulation, and How To Fix It
The metal framing around every window quietly undoes most of what your continuous insulation is supposed to do. Here’s what thermal window framing is, why Psi value matters, and how to specify it without overcomplicating the wall section.
Finally, Continuous Insulation That Keeps Up with the Speed of Modular Construction
The 2021 IECC now requires continuous insulation across all building types, and that requirement applies to modular construction. For manufacturers whose workflows were built around older code, this isn’t a […]
What Is a Building Enclosure? Components and Performance
Commercial buildings account for considerable energy use, making them prime candidates for innovative efficiency solutions through building enclosure system improvements. And, as energy codes tighten and sustainability becomes non-negotiable, design […]
Continuous Insulation for Energy-Efficient Airports
Energy efficiency is essential for reducing energy use and operating costs in traffic-heavy buildings such as airports. With large interior volumes, long operating hours, and constant exterior exposure, airport terminals […]
Stadium Construction: How To Deliver Thermal Efficiency at Scale
For expansive buildings, such as stadiums, structural stability and occupant comfort are essential success factors. Stadiums house thousands of people under one “roof,” and need to provide an environment that […]
Continuous Insulation for K-12 School Construction
No matter what kind of building you are designing for, the GreenGirt CMH™ continuous insulation and SMARTci® building enclosure systems are available to help your next project succeed by providing […]
Continuous Insulation for Terracotta Cladding
The GreenGirt CMH™ continuous insulation system is durable enough to handle any cladding weight and materials, including terracotta’s heavyweight design. This article explains the benefits of using GreenGirt CMH with […]
Window Thermal Bridging: How To Close the Gap at Every Opening
Legacy framing systems fail to eliminate thermal bridging at the most crucial points for thermal loss in any building: windows and openings. Ignoring this issue results in thermal inefficiencies that […]
