Polyisocyanurate (polyiso) exterior wall insulation is a high-performing closed-cell, rigid foam continuous insulation that is bonded to various organic and inorganic facers on both sides. Polyiso accounts for over 75 percent of the insulation used in new and retrofit residential and commercial construction in the U.S.
The Winter 2022 edition features two CEU articles to earn continuing education credits. These articles cover roofs for cold storage buildings and low-slope roofing air barriers and vapor retarders.
The Fall 2021 edition features our Special Coatings Section! We also have a number of features on open-joint cladding systems and the use of polyiso insulation with masonry wall systems. Read on as we discuss how design and building professionals should understand the importance of specifying colorful coatings with appropriate performance, longevity and sustainability.
The Mobile Convention Center’s existing 290,000-square-foot built-up roof was old and many of its expansion joints had separated over time. In some areas, water had penetrated into the seams, causing gas bubbles and blisters.
By their very nature, all building foundations touch the earth that surrounds them. In every climate, the water, air, soil, and temperature of that outside contact can impact the performance and integrity of the entire building structure.
High-performing family of roofing products effectively reduce standing water, while minimizing jobsite waste, labor, fabrication, and installation time.
From initial construction to eventual renovation or replacement, every building uses energy, water, and raw materials while generating waste and atmospheric emissions throughout its life cycle
With a closed cell polyiso foam core and inorganic coated glass facers, this high-density cover board from Johns Manville has a Grade 1 compressive strength and an R-value of 2.5.
