When evaluating insulation products, especially rigid foam boards like polyisocyanurate (polyiso), you’ll often encounter terms like R-Value and LTTR. While both are measures of thermal performance, they represent different things. Understanding the distinction is critical for architects, contractors, energy consultants, and building owners who want to make informed decisions about building envelope performance. Let’s break […]
The Build America, Buy America Act requires that all iron, steel, manufactured products, and construction materials used in covered infrastructure projects be produced in the United States. The act applies to a wide range of federal infrastructure projects, including those related to highways, bridges, public transit, and other public works funded by federal grants or […]
Over the past few decades, sustainability has been a growing focus in the building industry, with a significant concentration on reducing embodied carbon. Building industry stakeholders have recognized construction materials’ profound impact on the environment, leading to a heightened emphasis on sustainable practices. As a result, there has been a surge in efforts to minimize […]

When tackling options to reduce overall costs on a tapered roof system, designers look at a variety of specialty products including prefabricated target sumps, prefabricated hips and valleys, and extended panel profiles. The design of your tapered roof system determines if any of these options will benefit your “material cost vs. labor cost” totals. Insulation […]
Webster’s Dictionary defines R-value as a measure of resistance to the flow of heat through a given thickness of a material (such as insulation) with higher numbers indicating better insulating properties. The standardized measures of resistance to heat transfer were first recommended in 1945 by Everett Shuman, Director of Penn State’s Building Research Institute. R-values […]
It can be confusing to keep track of your climate zone code requirements due to the fact that the minimum insulation requirements have increased 66 – 100% over the last 9 years.
Mult-layering of Polyiso roof insulation installed with staggered joints offers a number of advantages over a single-layer system.
There are two recognized field test methods for determining uplift resistance of adhered membrane roof systems, both of which can be problematic
