Despite being the perfect application of cladding, weather-resistant barrier (WRB), foam sheathing, air barriers, studs and so forth, the perfect wall is not necessarily the most practical or preferred solution for every building project.
One analytical tool that can help you consistently determine code compliance and reliable performance is the freely available wall calculator developed by the Applied Building Technology Group (ABTG).
This article provides an analysis of three equivalent wall assemblies from a thermal performance perspective that have very different insulation R-value specifications: R-20 + 0ci, R-13 + 5ci, and R-0 + 15ci.
To equate an R20 + 5ci wall to an R25 +0ci wall when building with steel would be a very serious error since the cavity insulation is only about 50% effective in a steel frame wall.
In recent years, concerns with the use of foam sheathing and termite infestation risk have seen heightened interest.
SBCA has initiated the process for the development of an ANSI consensus standard and announces a call to solicit new consensus body members who wish to participate in the project committee.
The rainscreen cladding method features window flanges and furring mounted directly over any thickness of FPIS.
Applied Building Technology Group (ABTG) has developed a step-by-step guide for attachment of exterior wall coverings through FPIS.
To help builders and installers understand these challenges better, ABTG’s Jay Crandell presented, “Water, Water Everywhere and Not a Drop to Drink: Practical Building Science to Keep Walls Dry,” at the IBS Show.
The Applied Building Technology Group recently developed new, step-by-step window installation guides to help the industry follow best practices appropriate for a given window and FPIS application.
