When installing fire rated insulated doors and ceilings, it is important to understand that the "rated" rating refers to both the size of the door and the space it encloses. A door or a space that is heated is known as a "passive heat enclosure" while one that is not considered to be "passive" is called an "insulated door." These doors and spaces can have a significant impact on your heating costs and carbon footprint. In fact, many homeowners and building owners will often install a second door to enclose a poorly insulated room or area. However, if you are installing fire rated doors and ceilings, you should not do so unless you have the proper insulation installed.
Typically, fire-rated doors and ceilings will be manufactured from cold rolled steel frame, one-inch flange, and either melamine or fiberglass. Each one of these materials will provide excellent insulation, but only one is best for a particular application. The cold rolled steel frame is usually the most effective one when it comes to containing the heat inside of a room or area. This is because this material is tightly packed. This helps prevent the spread of fire due to thermal transfer. On the other hand, the one-inch flange provides a little more flexibility when it comes to cold insulation, but it is still effective.
If you are going to install a fire rated access door or ceiling, you should install a one-inch cold rolled steel door with an attached deadbolt. Additionally, you should purchase one-inch galvanized door bolts and hardware. One-inch galvanized door bolts are the recommended size for standard fire doors. Furthermore, if you are going to use a one-inch galvanized door, you should choose a deadbolt style that has a small amount of key relief.
Some people who choose to use a fire rated access door with a drywall panel or other framing are concerned about the moisture absorption of the panel or framing. In order to improve your insulation effectiveness, you should add mineral wool or insulation board between the wall surface and the exterior edge of the door. The mineral wool or insulation board can be installed right on top of the drywall or framing. To improve the moisture absorption efficiency of the door, you should use a continuous piano hinge. Continuous piano hinges have larger openings and wider channels in which moisture can enter.
An effective fire rated access door should also have proper insulation. For this, you should purchase interior trim products that are made of mineral wool or insulation board. You should also consider using high quality interior trim hardware that uses galvanneal steel for the frame and the channel. When it comes to the exterior trim, you should use non-metallic door handles. Finally, you should make sure that your fire doors are sealed with a water tight seal.
There are several benefits to installing fire rated access doors for your homes. They are designed to prevent the spread of fire from one area to another. They can also improve the energy efficiency of the entire structure. With proper installation and design, you can get energy efficiency up to 20% better than uninsulated walls. These doors should be sealed and have proper insulation for the walls to keep out heat and cold.
