It’s HOT in here!
Condensation, heat, and a hot metal roof are all aspects of owning a metal building in Louisiana. The sun beats down on your metal roof and can make the conditions unbearable during high temperatures in the summer. During the winter, heat from a heating unit will leak out of your metal building and make it almost impossible to keep your metal building warm when there is batt or fiberglass insulation. Closed cell spray foam can solve all these problems.
What is Closed Cell Spray Foam?
Closed cell spray foam is a rigid polyurethane foam that Sunlight Contractors layers at 2” along the roof sheathing, and walls causing a monolithic seal that creates an airtight barrier along with a suitable vapor barrier and thermal barrier. This creates a tremendous amount of strength and rigidity to the structure.
Louisiana’s High Humidity
The high humidity in Louisiana can also cause condensation problems if you do not install the proper insulation. Sun can bring the temperature of your metal roof to 160-170 degrees or more, and when the temperature drops as the day ends, the drastic change in temperature causes condensation like you have never seen . For example, if any other insulation is installed, open cell spray foam over the years will degrade it and drive mold growth and rusting of your metal roof, walls, and metal fasteners. On the other hand, there are quite a few benefits of using closed cell spray foam to insulate your metal building.
Make sure you have the proper insulation on your metal building. Closed cell spray foam is the answer.
