1. Florida product approvals are issued by the Florida Building Commission, do I need a NOA (Notice of Acceptance) issued by Miami-Dade County?

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. Click here to go to the Florida Product Approval Database.

2. What is the DP (design pressure) rating on your door panels?

Doors, by themselves, cannot be design pressure rated. Only complete assembled and framed door units or door systems are rated.

3. I've been told that my door must withstand 120 mph winds. Do your doors qualify?

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.

4. The fire labels were removed from my door, can you send me new ones?

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.

5. Are your doors rated for smoke and draft control?

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.

6. Is my door eligible for the US Federal Tax Credit?

To qualify for the US Federal Tax Credit, a building envelope component (door or window) must meet or exceed the criteria established by the International Energy Conservation Code (IECC) for the climate zone in which the product is installed. Many Masonite assembled door units may qualify in your zone. Click here for performance values of Masonite products and IECC prescriptive requirements.

8. What is an STC rating?

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.

9. What is glass U-Factor?

Glass U-Factor is the measure of heat loss through the door system. The lower the U-Factor, the better the insulator.
