Are you planning to add insulation to your Miami Beach, FL home? If so, you may need to obtain a permit from the local building department. According to the Florida Building Code, all work related to insulation requires a permit, including the outer insulating foam system (EIFS), cladding, or applications on metal slats or wire. Adding insulation to your basement can help it retain heat better and protect it from moisture and pests. The Florida Building Code requires that roof insulation materials have a minimum of R-30, while floor insulation must be a minimum of R-13.
To ensure that your building has a continuous layer of insulation around the entire envelope, you should use rigid panel insulation. You can measure the thickness of the attic insulation with a ruler and multiply the number of inches by the R-value of that particular insulation to get an insulation rating. If you're building a new home, you can consider installing insulation at the bottom of the roof covering and sealing the attic space, creating an “unventilated attic”. A good thermal barrier along the building envelope, such as high-R-value insulation in walls, attic and raised floors, as well as multi-paned glass, can help reduce conduction.
When calculating the R value of a multilayer installation, the R values of the individual layers are added together. If you wish to change contractors during the installation process, you must fill out a new permit application and select the “Change of Contractor” box located in the “Request for Permit” section.
