Gyp-Crete was only the beginning.
Maxxon, The Floor Specialists, is recognized as the pioneer and leader in floor technologies. From the original Gyp-Crete® Floor Underlayment, Maxxon's comprehensive product line has expanded to include gypsum and self-leveling underlayments, sound control mats, and several other specialty products including a low density deep fill.
Ideal for renovation, commercial, multifamily, or single-family applications, Maxxon can solve any floor challenge. Maxxon Underlayments can be installed in wood frame, concrete construction, or over corrugated steel deck in steel frame construction.
Maxxon gypsum underlayments, Level-Right, and Acousti-Mat Sound Control Mats are GREENGUARD Gold Certified. Maxxon products offer the complete package with fast installation, proven performance, and may also help contribute toward points for LEED® project certification.
New Product Highlights:
In an effort to reduce consumer confusion, the Acousti-Mat line naming conventions have been altered to feature straightforward product descriptions and reflect the way the AEC community discusses sound control...by thickness! To simplify product selection and leverage awareness of the Acousti-Mat brand name, Maxxon has established new naming conventions for the product line. Effective August 1st, 2018, the following naming conventions have taken effect:
All Maxxon entangled mesh mats will be known as Acousti-Mat®.
Each mat will be distinguished by thickness expressed as a fraction.
The High Performance (HP) upgrade will be retitled as "Premium". It will continue to be available as an option on the 1/4", 3/8" and 3/4" sound mats.
Please review the new product names:
Acousti-Mat 1/8.
Acousti-Mat 1/4, Acousti-Mat 1/4 Premium.
Acousti-Mat 3/8, Acousti-Mat 3/8 Premium.
Acousti-Mat 3/4, Acousti-Mat 3/4 Premium.
Acousti-Mat: Quiet Confidence.
There is a new option for deep fill applications where system weight is a consideration. Level-Right® LDF is a revolutionary, lightweight product made from Portland cement and a proprietary expanded polystyrene foam aggregate. The aerated foam aggregate gives the cement a range of unique properties, making it perfect for deep fill applications.
