This piece is co-written by Kristin Westover The headaches of Cold Storage facility operations extend beyond making sure the ice cream doesn't melt. Owners and Operators are regularly challenged with: Selecting a cost-effective roof system that is going to be long-lasting Working around unsafe areas in the interior due to ice accumulation Struggling to reduce monthly energy bills
The polyiso insulation you choose for your commercial roofing project can make a big difference in terms of durability and performance of your roofing system. But with so many options on the market, it can be easy to get lost in the details and risk choosing the wrong material for your project.
With the misinformation swirling around the topic of moisture in concrete roof decks, it can be difficult to know the right approach to take to mitigate risk. Are roof failures due to moisture in concrete primarily found in lightweight concrete decks? Do vented decks alleviate moisture in concrete by facilitating downward drying? Is 28 days the right amount of time to let a new concrete deck cure? Are admixtures and MVRA's (Moisture Vapor Reduction Additives) effective in mitigating concerns around moisture in concrete roof decks? Are vapor retarders the answer? What about vented base sheets? What adhesives and insulation and cover board facers are appropriate to use in these roof assemblies?
Can Energy Efficiency be Further Improved? The energy efficiency of a building's enclosure is generally analyzed in terms of thermal resistance. This is a static property and doesn't take into account the time of day and the effects of thermal mass. This article shows how adding thermal mass to a roof assembly might offer a way to improve energy efficiency, especially for buildings only occupied during daylight hours such as offices and schools. In addition, thermal mass could help reduce electric grid demand swings.
