Ecosystem protection has been enhanced by the practice of obtaining wood from certified, well-managed forests. What was previously considered waste wood byproducts are now being recycled into composites and used as hidden components of windows, skylights, and doors. The positive pressure test is designed to reflect real situations based on the theory that heat expands the air, increasing the air pressure in the room or space where the fire is. The new test specifies that after five minutes into the test, the neutral pressure level in the furnace shall be established 40 inches above the sill. The most basic requirement calls for doors to be wide enough for a wheel-chair bound person to swing the door open and maneuver through the doorway.
Windows are to require no more than five pounds of force to push, pull, or lift.
