CAT II vs CAT III Sunrooms
We have a lot of customers ask us "What is the difference between CAT II & CAT III Sunrooms." I have posted below the technical specifications from Sumter County. It's not about what the CAT II is, it's about what it is Not. A CAT II sunroom does not stop water or air leakage. Why would you pay the same or even more to clean up water leaks or not be able to properly heat & cool you lanai. Don't sign an affidavit for a CAT II sunroom when you are paying for CAT III products anyway. By doing that you are letting your contractor off the hook for any and all service work down the road. Hire a company that clearly explains your options and will provide the service that goes along with it.
CAT II: The space is covered by a roof and the walls are enclosed with translucent or transparent plastic or glass. The space is defined as nonhabitable and unconditioned space. There is no requirement to submit any energy calculations or meet the requirements of electrical outlet wall spacing per the National Electrical Code. The sunroom requires a light on the exterior side of the entrance to the sunroom. CAT III: The space is covered by a roof and the walls are enclosed with translucent or transparent plastic or glass. The space must comply with requirements for forced-entry resistance, air-leakage resistance, and water-penetration resistance. No requirement to meet the electrical outlet spacing per the National Electrical Code. Air-leakage areas of concern all joints, seams, and penetrations, including openings between window and door assemblies and their respective jambs and framing, walls between the dwelling and the sunroom, and other sources of infiltration. The air-leakage is per the Florida Energy Conservation Code. The sunroom requires a light on the exterior side of the entrance to the sunroom. |
