NEUTRAL VS. POSITIVE PRESSURE

The Underwriters Laboratory (UL) and Warnock Hersey (Intertek Testing Services) are the entities that test and rate all fire doors. To properly rate the door, it must be tested as a complete unit with hardware and installed on a wall with a test environment behind it. The primary purpose of the test is to ensure the door can contain the spread of the fire. A neutral pressure area is below the pressure plane, and a positive pressure area is above the plane. Neutral Pressure Neutral pressure assumes the pressure plane to be

Positive Pressure Positive pressure assumes the pressure plane is 40” from the bottom of the door. Air flows into the room at the bottom, but flows out at the top. Along with the circulating air, dangerous gases or flames may also escape causing the door’s face to burn.

above the top of the door, and the pressure will not build up in the room containing the fire. Air flows into the room at the bottom and top of the door preventing flames from spreading. A weatherstrip helps to eliminate the smoke leaving the room.

How to Choose a Fire-Rated Door STEP 1 Determine if a fire rating is required.

Laws and regulations regarding fire ratings can vary between states, cities, townships, and municipalities. Always be sure to check all regulating authorities to ensure the door units you order and install will comply with applicable laws. SBP® offers two types of fire-rated doors: 20-Minute and 90-Minute . STEP 2 Choose a door. After determining what fire rating is needed, the next step is choosing a door style.

STEP 3 Choose a frame.

To choose the correct frame type, determine if your wall construction is drywall or masonry. If drywall, SBP offers two types of steel frames: hollow metal and commercial split steel. Masonry frames are hollow metal.

STEP 4 Select your hardware and accessories.

SBP offers an extensive line-up of commercial hardware that can be used for residential and light commercial uses - including exit devices, closers, locks and more.

Choosing a door’s rating is important, but the unit’s rating is dependent on all the components used. The lowest rated item in the entire unit determines the rating. For example, a 90-minute rated door placed in a 20-minute rated frame has a 20-minute rating.

90-Minute vs. 20-Minute Units

90-MINUTE UNITS A 90-minute unit is created with a steel-edge door and a split steel frame. The Reeb® Specialty Products (RSP) steel-edge doors have an entire steel edge creating a sturdier steel door. These doors are insulated with polyurethane cores that are tested to withstand at least 90 minutes of fire exposure. The RSP split steel frame accompanies this door to create a 90-minute unit. Full Steel-Edge Door Polyurethane Core

20-MINUTE UNITS There are a few ways to create a 20-minute unit. RSP steel-edge doors can pair with a 20-minute wood or composite frame, and the 20-minute frame can pair with wood-edge doors. Therma-Tru® wood-edge doors have a polyurethane core for insulation. These fiberglass and steel doors were tested to withstand at least 20 minutes of fire exposure. The 20-minute Therma-Tru® doors can also pair with the 90-minute RSP split steel frame for easy installation based on the application need.

REINFORCED DOORS

Steel-edge doors with a bore may also need a door closer, while doors with no bore will need panic hardware. Additional reinforcements are necessary to ensure the door will stand up to continual usage. A reinforced door includes additional material on the back of the door skin for extra protection.
