Cemplex Group® understands that it is important to look for opportunities to improve construction practices. Saving time, creating a more durable installation, or just making a process safer are often the lenses which we look through.
Gypsum and sound reducing underlayments are a familiar pairing on most multi-family construction sites. Pairing these two products offers a fire resistive, sound attenuating substrate that owners and tenants both require and appreciate. The weak link in this chain has always been the compressibility of the sound mat. Placing a readily compressible sound underlayment beneath a thin layer of poured gypsum cement, frequently leads to cracks and deterioration of the gypsum which telegraphs through the finished flooring.
Construction processes often require sequencing of the building process. This sequencing ensures that you do not have conflict or incompatibility issues on the jobsite. Traditionally, drywall installation occurs before gypsum and sound mats in this portion of the sequencing. Since the advent of sound mats, the drywall installation has always gone first due to the compressibility of the sound mat that resides under the gypsum. A fully loaded drywall delivery cart rides on urethane wheels, which can exert thousands of pounds per square inch on the gypsum which causes widespread failure due to the deformation of the sound mat under heavy load.
The answer to this challenge is an uncompressible sound reducing mat from Formulated Materials® known as Treadstone™ Elite. Elite offers patented sound reduction exceeding industry standards all while offering unparalleled rigidity. Combining the Elite underlayment with a properly batched Treadstone® FR25 or FR30 gypsum underlayment will yield a floor that can withstand greater than 2,500 PSI.
