Floor Trusses

One of the most significant benefits of SBC Magazine’s new online polling approach is it gives component manufacturers (CMs) a glimpse into how their business model and/or local market compares to the industry as a whole. 

Open web trusses are the ideal match with a sprinkler system, maximizing use of space and making installation easy.

This research report will focus on manufacturer or trade association deflection requirements for a number of floor topping/covering related products where deflection requirements may impact serviceability.

Lumber Design Values

No matter the species, component manufacturers (CMs) purchase and rely on the accuracy and reliability of many different lumber design properties, including: bending (Fb); shear parallel to grain (Fv), compression perpendicular to grain (Fc^), compression parallel to grain (Fc), tension parallel to grain (Ft), and modulus of elasticity (E and Emin).

Question: 

A condominium project I am involved with is experiencing a sound transfer problem through the floor/ceiling assembly between the first and second floor. You can hear every footstep, from an adult to a child. The floor assembly consists of a carpet and pad, 3/4 in. OSB sub-flooring, 15 in. deep wood trusses at 16 in. on center, 9 in. fiberglass batt insulation and a 5/8 in. gypsum board ceiling. The trusses span 20 ft. with air/heat ducts between the trusses. Will an additional layer of 5/8 in. gypsum board attached to 7/8 in.

Question: 

Does SBCA produce any products detailing how to market and sell roof and floor trusses to builders for whom stick framing has been the standard way of building? Products that detail the cost savings when compared to traditional stick framing?
