    "All three figures are maximum permitted leakage, not zero.",
    "A product meeting the USACE Type 2 criterion is permitted roughly fifteen times the leakage of one meeting BS 851188.",
    "No manufacturer of removable aluminium panel systems sold to Florida homeowners holds ANSI/FM 2510, ourselves included.",
    "Florida Product Approval and Miami-Dade NOA are wind and impact schemes (TAS 201/202/203). They do not evaluate flood performance.",
    "Under FEMA Risk Rating 2.0, three residential premium levers are elevating the building, elevating machinery and equipment, and installing compliant flood openings. Dry floodproofing is not among them."
