PIMA releases research report demonstrating that the R-value of polyiso roof insulation shows no significant variation within the average winter and summer temperature ranges across North America.
Johns Manville (JM) has announced that JM Corbond III® closed-cell spray polyurethane foam insulation now delivers an R-value of R-7 per inch, a change that translates to a 9-percent increase in thermal resistance compared to the previous R-6.4 per inch.
Daylighting is the use of natural light as a main illumination source from a myriad of glazing devices in both vertical and horizontal positions within a building.
The Walgreens distribution facility in Windsor, Wis., was originally built in 1980 with a standing seam steel roof offering an R-value of 9.5. Owners decided it was time to improve the energy efficiency of the distribution center and hired RRK Associates, Ltd., to carry out the project.
