No. Both documents are valid methods of demonstrating compliance to the same building code. Florida law provides manufacturers alternative means of demonstrating compliance so long as the products are tested or evaluated to the applicable standards.

Doors, by themselves, cannot be design pressure rated. Only complete assembled and framed door units or door systems are rated.
There is no test for doors or windows specific to wind speed. All industry test standards establish design pressure ratings. The design pressure required for a specific installation depends on several factors (not just basic wind speed) and should be determined by an architect or engineer of record. View our Coastal Door Collection brochure for specifics.
Unfortunately, no. Masonite is only authorized by the fire rating agency to apply fire labels at our manufacturing locations. Intertek (Warnock Hersey) can be contracted, at a fee, to conduct a field inspection and label a door that is installed.
Smoke and draft control is a function of the gaskets that are applied to a door unit upon installation in a home. Any positive pressure rated door is eligible to become a smoke and draft control door when Category H, Smoke and Draft Control gaskets are applied.
Masonite steel and fiberglass doors with polyurethane foam core have an estimated thermal performance value of R-10. This R-value calculation is based on common published conductivities of door component materials (i.e. foam, steel and fiberglass facings).
STC (Sound Transmission Class) are measurements of a door’s ability to reduce airborne noise. Higher STC values represent better reduction of noise. Click here for Masonite’s acoustical performance data.
Glass U-Factor is the measure of heat loss through the door system. The lower the U-Factor, the better the insulator.
The SHGC solar heat gain coefficient is the fraction of solar heat admitted through the door glass unit.
