We add R4 insulation to provide a minimal level of protection; however a vapor barrier and additional insulation must be added to meet local requirements.
The size options for manufacturing CYCLONE® products vary depending on the specific product. We offer a range of sizes that have been thoroughly tested and meet our quality standards. The sizes must be within the range of the smallest and largest tested options to ensure compliance. We can provide guidance and assistance in choosing the appropriate size for your specific requirements.
