Thermal Bridging: Why Standard Insulation Fails in Coastal Virginia
In the Tidewater region, most homeowners focus on R-value—the measure of thermal resistance. However, a high R-value is meaningless if your roof suffers from thermal bridging. This occurs when heat bypasses your insulation via highly conductive materials like wooden rafters or metal fasteners. In the intense Chesapeake humidity, this temperature differential leads to "internal sweating," where moisture condenses on the underside of your roof deck.
The Continuous Insulation Solution
At Aquashield, we advocate for structural solutions that break the thermal bridge. By utilizing high-density polyisocyanurate (ISO) boards during a roof replacement, we create a continuous thermal envelope. This prevents cold spots on your ceiling and drastically reduces the energy load on your HVAC system during those brutal 100-degree July afternoons.
