We have always been told that concrete slabs placed directly on a vapor retarder curl more than slabs cast directly on a prepared base. However, we recently measured a slab that we know had a vapor barrier only in limited areas. The portions cast oyer the vapor retarder had less curling than those cast directly on the base. What is the current industry understanding of this issue?

Architects, Engineers and Contractors often need to know how much an installed ceiling system will approximately weigh. The following are suggested guidelines of material weights are for hanger wire and fastener selection. The actual weights may vary with proprietary products or additional materials added.

The importance of location of the proper air barriers, vapor barriers and waterresistive barriers on the wall and the roles they play in high‐performing EIFS

INTRODUCTION

In the last few years more specifications are being written to include the requirements for air barriers, vapor barriers and water‐resistive barriers. Some of these emerging specification requirements are a result of mandates by local building codes while others are a result of promising building science and research.

In recent years there has been an increased focus on the use of “air barriers.” particularly for commercial, hotel, institutional and high-rise construction. The heightened awareness of moisture intrusion, mold, and unhealthy indoor air quality on some buildings, has led researchers to re-examine and refine the air movement through exterior walls. Air movement through a building’s exterior walls is a concern as the air can carry moisture which impacts water sensitive materials, structural integrity, indoor air quality (air pollutants and microbial reservoirs) and thermal energy.

Code requirements for bracing, resistance to transfer loads and seismic considerations of non-load bearing partitions are based on ASCE and ASTM standards. Many of the allowable options for bracing of these non-load bearing partitions are covered in TSIB Technical Bulletin 20.100.

Attachment of floor and ceiling tracks (top and sill) to concrete and/or metal pan decking shall comply with ASTM C 754. Attachment of track to non-load bearing partitions to concrete substrates may be attached using power driven/actuated fasteners (see detail).
