Sweating AC duct and attic water damage caused by the Paston Effect (cold attic syndrome) — exactly what the Airtight Comfort System™ is designed to fix. South Florida homes face a unique combination of challenges: extreme heat, relentless humidity, and attics that routinely hit 120–150°F. These conditions cause:
The majority of insulation companies overlook these problems entirely, and very few specialty firms in Florida are equipped to correctly resolve sweating AC ducts, attic mold, or the Paston Effect (cold attic syndrome).
Three integrated components: high-performance spray foam insulation, attic pressure stabilization, and dedicated moisture and humidity control.
Traditional insulation companies limit their work to spray foam installation. They do not evaluate or correct attic pressure dynamics—positive or negative—nor do they manage moisture with dedicated dehumidification systems.
Only Airtight Spray Foam Insulation engineers all three to work together as one system — customized to your home.
