Exterior entry doors are one of the most vulnerable aspects of the home in a huuricane. According to Tom Kraeutler, home improvement expert and host of The Money Pit radio show, “The roof, windows, garage door and entry doors to the home are considered the primary susceptible areas when severe weather strikes. If one of these key structural products is penetrated during a storm, then the entire home is at risk for catastrophic wind, debris and water damage.”
Therma-Tru® Tru-Defense® doors and entryway systems are designed to help protect against hurricane damage. The Tru-Defense® fiberglass door system, includes a package of precision-engineered components. When combined into one entryway system, these important pieces deliver long-lasting durability that can stand up to severe weather conditions.
With impact-rated glass they are designed to meet building codes across the country, including in severe weather zones. They offer impact-rated glass options for its fiberglass and steel entry and patio doors, which meet wind-borne debris region requirements throughout most of Florida.
For the stricter High Velocity Hurricane Zone (HVHZ) requirements in Miami-Dade and Broward Counties (and for homeowners desiring the ultimate in a secure door) Therma-Tru also offers a line of impact-rated fiberglass and steel doors that are tested to withstand more severe weather conditions. The impact-rated fiberglass doors are designed with a steel plate inside to help withstand hurricane force winds and debris, and are approved for HVHZ.
These opaque impact doors have a structural performance of up to design pressure (DP) 100. This is equivalent to 242 mph winds. Additional options include using Impact-rated glass with an impact-rated door or a selection of Impact-rated sidelites with an Impact-rated door to qualify for HVHZ approvals. (Please check with the manufacturer for exact specifications).
The composite adjustable sill of the Tru-Defense door system allows for a weather-resistant seal with the door bottom to help prevent moisture damage. The stainless-steel tongue construction and three-point locking structure on the multi-point locking system provide exceptional stability and security. And, the heavy duty ball-bearing hinges provide support, stability and smoother, longer-lasting performance.
On inswing Tru-Defense door systems, moisture and air infiltration are greatly reduced by the dual-bulb bottom sweep design that works with the weatherstrip and the 7-shape corner seal pad. The foam-filled compression weatherstrip remains flexible and helps seal against air and water.
Failure of a Therma-Tru fiberglass entry door that has been installed with all the specified Tru-Defense components may qualify for a reimbursement of up to $2,000 that can be used toward product or component replacement or secondary damage repairs (Please check with manufacturer for details).
