Improved Performance We started Mason Industries in 1958. Our revolutionary designs of high deflection free standing spring isolators, as opposed to housed mountings, and our literature with down to earth information made its mark. This generated phone calls from acoustical consultants asking us to get into the floating floor business. We asked why. In addition…
Concrete Floating Floors Concrete floating floors are used for many purposes. We have limited this bulletin to the following areas of Vibration, Sound and Impact Isolation. 1. VIBRATION ISOLATION Buildings are unavoidably near busy streets, trains and subways even though they contain space that must be vibration free and have very low NC levels. Examples…
ARCHITECTURAL CEILING HANGERS Floating Floors remain the most effective way of reducing sound transmission and vibration from the floor above. However, there are many situations where a floating floor is impractical or not economically feasible, so an isolated ceiling becomes the practical choice. There are two types of ceilings. There are the simple acoustical tile…
Floating Floor Structural Test PURPOSE OF TESTS To determine maximum loadings on reinforced concrete slabs supported by flexible .elements of unlimited deflection spaced 48″ apart. LOADING METHOD Placement of.500 lbs and 1000 lbs certified steel weights provided by the Howe Richardson Scale Company. 500 lb weights were approximately 12″x 12″ x 12″. 1000 lb weights…
Floating Floor Acoustical Field Test The acoustical tests discussed and reported here were conducted by Cerami and Associates, Inc. on July 1 and 2, 1974 in the T.V. Studio of Standard Oil of Indiana Company at the above referenced test location. The purpose of these tests was to measure the Impact Noise Rating (INR) and…
Intro Walls are isolated to prevent flanking around floating floors or to improve the STC between adjacent spaces. The word “flanking” is used to describe a vibration or noise path that goes around an isolated component. If a structure is built with continuous walls so that in cross section it is as an H and…
Intro When you need a floating floor to dramatically Increase your Sound Transmission Class and Impact Noise Rating Why not use the MASON JACK-UP FLOOR SLAB SYSTEM and eliminate the cost and need for: Combustible, rot prone plywood forms. A myriad of transmission paths through closely spaced supports. Moisture retaining fiberglass infill that plugs sub-drains…
