WOOD JAMBS

20 & 45-Minute UBCVT’s’ fire-rated door jambs are approved for use in positive pressure in-stallations. Jamb labels do not have any reference to positive pressure and are not supplied with edge seals. The opening will meet positive pressure requirements only when a positive pressure labeled door is installed with an edge seal system approved for use with that door.

• Category A Doors: This category includes doors that are listed for use as fire doors without the use of field installed edge seals (such as intumes-cent).

• Category B Doors: This category includes doors that require the field installation of a listed edge seal to meet their fire protection rating.

The new codes also require gasketing to meet the smoke control require-ments of UBC 7-2-2 (1997). The gasketing completely conceals the intu-mescent on the jamb.

Fireguard PlusVT’s Fireguard jambs have a number of advantages and features not available with solid lumber or metal jambs.

Most important is the fact that jambs and door lites, or panels, can bematched in any commercially available veneer species. This assures a superior color match when compared to solid lumber or metal jambs.

Veneered jambs also have the following advantages:• Increased resistance to denting compared to many moderately soft hardwoods such as mahogany, walnut and cherry• Increased stability eliminating the risk of twisting or warping• Ease of repair—nicks and chips can easily be patched and touched up• Easier to install than a three-piece jamb• Supplied finish sanded• Generally lower cost than solid lumber, especially with the more exotic species
