Each case study offers unique conditions that make it especially interesting to discuss. In the case study we first identify the problem and the expected outcome. Then, after the radiant barrier foil is installed, we determine the ways it improved the problem and, in some cases, even some unexpected benefits that came from the installation.
Background: This customer builds habitats for bats, and so far they have provided enough housing to shelter around five hundred thousand bats and counting. They built a new shop and were looking to keep the temps moderate enough for the bats to stay comfortable.
Type of Structure: wood-framed metal building with wood trusses & studs
Install Date: July 2012
Goal: Keep habitat climate controlled for bats; stopping heat gain in summer (or sunny days) was the main goal.
Product Used: Double-Sided Radiant Barrier Foil
Install Details: The foil was installed inside each stud cavity, with an air gap being between the exterior sheathing and the foil (this is a typical wall installation), followed by the regular r-value. The foil on the roof was placed directly on to the deck, before the trusses were put up.
Finish: The customer finished the wall cavities with insulation and covered it with plywood.
Results: The customer was very pleased with the results - the foil was making the interior of the building much cooler. On an 89 degree day (metal reading 102 degrees), the inside reading of the foil was 85-88 degrees - at ambient temperature without any air conditioning.
