UL HW-D Listings by Movement Table Description and Download.

UL HW-D Listings by Movement (PDF Download)

The UL HW-D Listings by Movement download is a comparison table of U.L. HW-D Listing Information taken from the 2004 U.L. Fire Resistance - Volume 2A Directory.

The six page comparison table provides a quick movement summary for fire rated head-of-wall deflection joints. Deflection and extension movements shown are maximum movements provided by the tested system. The following is an example of the table layout:

• Column 1 - UL Listing No.
  The number UL assigns to the tested assembly. Refer to UL Directory for further information.
• Column 2 - Sponsor
  This is the company that paid for the listing.
• Column 3 - Hourly Rating
  This refers to the hour rating on the wall that was tested. The wall must be tested For example, a 2 hour listing cannot be used on a 1 hour wall.
• Column 4 - Nominal (Installed) Width by “
  This refers to the amount of material (ie. fire caulk or spray) or gap spacing that needs to be installed. It does not reflect the actual movement capability of the system. Actual movement (deflection) is determined by multiplying nominal joint width by percent of compression or extension. Please refer to the section below on Understanding Nominal Joint Width.
• Column 5 - % Compression (Deflection) Movement
  This refers to the percentage of the nominal joint width that testing has determined the system can move (deflect). This percentage is determined by U.L.
• Column 6 - Actual Compression (Deflection) by “
  This refers to the actual amount of movement (deflection) in inches the system is tested for. This figure is determined by multiplying the nominal joint width (Column 4) by the percentage compression (column 5).
• Column 7 - % Extension Movement
  This refers to the percentage of the nominal joint width that testing has determined the system can move (extend). This percentage is determined by U.L.
• Column 8 - Actual Extension by “
  This refers to the actual amount of movement (extension) in inches the system is tested for. This figure is determined by multiplying the nominal joint width (Column 4) by the percentage extension (Column 7).

This table is intended as a reference tool for quickly determining if a fire rated head-of-wall system meets the deflection (Column 6) and hourly rating (Column 3) requirements of the project as set forth by the Architect or Structural Engineer and spelled out in the project specifications.

Understanding Nominal Joint Width (Installed Width) And Actual Movement in U.L. Listings

Nominal Joint Width in U.L. listings refers to installed width. Nominal Joint width does not equal movement capability because the joint material can only move a percentage of its thickness. For example, systems that require fire caulk or spray can only move a percentage of their nominal joint width because they are limited by compressibility, elasticity or bond strength. To determine actual movement you must multiply nominal joint width by the percentage of compression and/or extension.

For illustration: A 1“ nominal joint width with 25% compression has an actual deflection capability of only 1/4“.

The Fire Trak System, when installed at a nominal joint width of 1", has a full 100% movement in compression for a full 1“ of deflection. By extension of track depth, the Fire Trak System can move 1“ (100%) in both compression and extension for a combined range of movement of 2“.

The Fire Trak System is U.L. tested and listed at 1“ and 3“ nominal joint widths with 100% movement in both compression and extension for combined ranges of movement of 2“ and 6“. The Fire Trak System can have any range of movement from 1“ to 6“ in 1/2“ increments.
