| New gypsum concrete floor underlayment  With the increased cost of land and the resulting need for higher density projects, Hacker Industries, Inc. unveils a new gypsum concrete floor underlayment formulated for use in buildings with light-gauge steel framing and a corrugated steel deck. Blending high strength and versatility, FIRM-FILL CSD offers a minimum compressive strength of 3500 psi and is installed thinner than typical poured-in-place concrete. Installed at 1" above the top of the steel deck flutes (average nominal thickness is 1-9/16"), FIRM-FILL CSD is significantly lighter thereby reducing deadloads and the related steel framing costs.The remarkable strength and speed of installation of FIRM-FILL CSD provides steel framing projects the flexibility to add floors quickly. The underlayment technology provides a significant scheduling advantage since it dries in approximately 10 days. Under standard drying conditions, FIRM-FILL CSD sets in two hours and tolerates light trade traffic the following day. In addition, FIRM-FILL CSD is UL-rated providing 1, 1-1/2 and 2 hour fire ratings as listed in UL G565. FIRM-FILL CSD is installed on site exclusively by Hacker Industries's trained, Licensed Applicators to ensure product consistency and quality. Hacker Sound Mat II can be added to the system to provide additional sound control and to meet building codes. write your comments about the article :: © 2008 Construction News :: home page |
