Improving Floor/Ceiling Sound Control in Multifamily Projects: Sound Testing Practices

The sound transmission class (STC) and impact insulation class (IIC) are ASTM-derived single number ratings that try to quantify how much sound a stopped by partition being tested. Laboratory testing involves an ideal setting for the floor/ceiling assembly—it is isolated from the walls, and there are no penetrations for HVAC, plumbing lines, sprinklers, can lights, or electrical boxes. In the field (i.e. F-STC and F-IIC), the floor/ceiling assembly often sits on load-bearing walls, is connected to the structure, and contains many ceiling and floor penetrations for the items just mentioned. Consequently, the code allows for a lower rating for field scores over those in the lab.

The goal of a room air distribution system is to provide thermal comfort and a healthy living environment for occupants in the space. This article looks at designing such assemblies for comfort and indoor air quality (IAQ) per ASHRAE 55 and 62.1. It examines the common method of overhead distribution, but focuses on partially mixed (i.e. most under floor air distribution [UFAD]) and fully stratified (i.e. displacement ventilation) systems.

Specifying the Right Grout for the Job

Specifiers typically select the grout for their tile project based on general performance characteristics, color, warranty, and cost. Despite this, less-than-optimal products are often used. Some do not fully understand the changes in grout technology and do not realize they have a choice. Not all grout is the same, and, of course, color is only one small factor in the overall performance.
