TruStile® Interior Doors

Fire Doors & Frames

Safety without style compromise

Throw away the preconception that you have limited design options for fire-rated openings. With hundreds of styles and unlimited custom capabilities, TruStile ensures you will never sacrifice style when selecting 20- through 90-minute fire doors.

Maintain Design Consistency

Designed to match non-rated doors

You no longer need to settle for flush doors with plant-on mouldings when it comes to fire doors. All TruStile fire doors feature full panel relief and are carefully engineered to match our non-rated doors. You’ll achieve a clean, consistent look with the same details you demand on your standard doors.

1-3/4" thickness up to 90-minutes

Other manufacturers force you to make the jump to 2-1/4" thick doors for higher fire ratings. Not TruStile. TruStile have specially engineered and tested fire doors to maintain a standard 1-3/4" thickness up to a 90-minute fire rating.

20-minute fire-rated glass doors

With TruStile, you never have to sacrifice style for fire door safety. Now you have the flexibility to specify glass doors in 20-minute ratings. Virtually all of TruStile’s TS series and one-lite FL and PL series doors are available with 20-minute ratings.

Custom capabilities

TruStile can work almost any custom design feature into our 20- through 90-minute doors. Send us your desired design and fire rating and our engineers will show you how we can carry it through all of the doors on your project.

A Fire-Rated Wood Frame System That Complements Your Doors

Most commercial fire-rated openings feature hollow metal frames that do not match the non-rated doors with which they are paired. TruStile offers a revolutionary new frame system that provides the desired appearance of natural wood in 20- through 90-minute fire ratings. This means that TruStile wood and MDF fire doors can now be paired with a matching frame in any stain-grade wood species or paint-grade poplar. The result is a uniform architecturally-correct look on all doors, frames and millwork across a project.

Fire-rated jambs can be veneered in any stain-grade wood species

  • Fire ratings up to 90 minutes
  • Veneered in any stain-grade wood species to match doors and millwork
  • Availability in any size (up to 8 feet tall) for single and pair openings

TruStile Fire Door Offering

TruStile offers paint-grade and stain-grade doors in 20- through 90-minute fire ratings. Our positive pressure doors are manufactured with our patented FireWedge (Patent Number: 6,115,976). The FireWedge includes an intumescent strip in our poplar Wedge Edge®, which expands and provides a smoke seal when heated.

Positive Pressure Fire Door Overview

All TruStile fire doors comply with the following standards: UBC7-2-1997, UL 10-C (positive pressure), NFPA 252 (1995), ASTM-252, and UL10-B (neutral pressure).

The standards for the design, testing and certification of fire rated openings changed when the International Building Code adopted the 1997 Uniform Building Code (UBC) 7-2-1997. With the adoption of this code came the requirements for fire rated openings to be tested under positive pressure in accordance with UL 10-C. Positive pressure testing of fire rated openings more accurately reflects the conditions of a real fire. However, the change from neutral pressure to positive pressure significantly impacted the dynamics of the door and hardware which is located above the 40” neutral pressure plane.

In order to successfully pass a fire test under the new positive pressure requirements, it is necessary for wood door manufacturers to provide doors with listed and approved intumescent seals or gasketing. The WDMA (Wood Door Manufacturers Association) describes positive pressure openings in two categories, Category A and Category B.

Category “A”

Category “A” doors have sealing systems built into the door edges and therefore do not require any additional edge sealing systems between the door and frame. The sealing systems can either be visible or concealed within the edge of the door. All Positive Pressure TruStile Fire Doors are manufactured as Category “A” with concealed sealing systems.

Category “B”

Category “B” doors do not have sealing systems built into the door edges. These doors do require additional listed and approved edge sealing systems between the door and frame. These sealing systems are generally surface applied to the door and/or frame. Category “G” describes edge sealing systems which meet this listing requirement. In some cases, Category “G” sealing systems might be required on the meeting stiles of pairs of Category “A” doors.

Smoke Seal Labels

In addition to standard fire ratings (A/3 hour, B/90 or 60 minute, C/45 minute and 20 minute), some positive pressure doors may also be required to carry a smoke seal (“S”) label. In these cases, the doors and frames will bear two labels. One indicating the fire rating (fire label) in minutes and the other indicating the opening is smoke rated (smoke label). Category “H” describes sealing systems for doors and frames to meet this listing requirement.

Consult NFPA 80 to review requirements for the installation of fire doors and windows.

Please note: it is the responsibility of the door distributor to inform the manufacturers of what the code requirements are for the fire doors and frames on a given project.
