14" x 14" BA-FW-5050-ACF Acoustical Fire-Rated Insulated Access Door

The 14" x 14" BA-FW-5050-ACF Acoustical Fire-Rated Insulated Access Door is designed for commercial wall assemblies that require both fire protection and sound control.

Built with a 20-gauge steel door on a 16-gauge mounting frame and filled with 2" of fire-rated insulation, it provides a Warnock Hersey fire rating of up to 1.5 hours while also helping reduce sound transmission through the opening.

Tested to STC 29 and OITC 24 for sound, this vertical-installation door suits demanding interior walls in institutional and commercial spaces. Fire-rated access doors do not stop fires from starting; they help slow down the spread of a fire for a limited period.

Why Choose 14" x 14" BA-FW-5050-ACF Acoustical Fire-Rated Insulated Access Door?

• Certified Fire Rating: Warnock Hersey fire-rated up to 1.5 hours and certified to UL 10B and CAN/ULC S104, with a maximum temperature rise of 250°C (482°F) after 30 minutes, so the opening maintains the rating of the wall.
• Acoustical Performance: Tested for sound transmission to ASTM E413 STC 29 and ASTM E1332 OITC 24, helping minimize sound transmission through the access opening, supporting quieter commercial environments.
• Insulated Construction: A door filled with 2" of fire-rated insulation intended for wall assemblies where both fire resistance and temperature-rise performance are important.
• Rigid Steel Build: A 20-gauge steel door on a 16-gauge mounting frame with a 1" mounting flange stands up to repeated service access.
• Self-Latching Operation: A universal self-latching bolt that automatically secures the door after use, supporting code-compliant operation and reducing the risk of accidental openings.
• Field-Ready Finish: Ships with a baked white prime coat suitable for field painting to match the surrounding wall.

What Should You Know About Rough Opening and Installation Requirements?

Required Rough Opening

The BA-FW-5050-ACF wall opening quals the W + 3/8” (9 mm). For instance, a nominal 24" × 24" door requires a wall opening 24?" wide.

Always verify the rough opening dimensions against the approved submittal drawing before framing to ensure proper fit and rated performance.

Compatible Applications

This door is designed for fire-rated interior walls where heat transmission and sound control are factors. Typical uses include:

• Educational facilities where quieter learning environments are important.
• Hotel and multifamily demising walls requiring both fire protection and acoustic separation.
• Broadcast, performance, and conference facilities with acoustically sensitive spaces.

Installation Notes

• Install vertically only; this model is not rated for horizontal or ceiling use.
• Install in a fire-rated wall assembly consistent with the door's label.
• The self-latching bolt supports code-required closure.
• The baked white prime coat is suitable for field painting after installation.

Frequently Asked Questions About Acoustical Fire-Rated Access Doors

What do STC 29 and OITC 24 mean?

They are sound-transmission ratings measured under ASTM E90. Higher numbers indicate greater resistance to sound passing through the assembly; these ratings describe how the door performs acoustically at the opening.

What does the fire rating cover?

The door is Warnock Hersey fire-rated up to 1.5 hours and certified to UL 10B and CAN/ULC S104, with a maximum 250°C temperature rise after 30 minutes. Fire-rated access doors do not stop fires from starting; they help slow down the spread of a fire for a limited period.

Why is this door vertical-installation only?

Its fire and acoustic performance were tested in a vertical wall orientation, so it should be installed vertically to perform as rated. For ceilings, specify a door tested for that application.

Can it be prepared for master keying?

Yes. Mortise cylinder lock preparation for master keying can be added and must be specified at the time of order.
