In wood construction the typical system includes:
• Resilient Entangled Net material on top of plywood subfloor in conjunction with gypsum underlayment.
• Insulation in the joist cavity.
• Resilient Channels & gypsum board on the ceiling below – Low Frequency Control.
In concrete construction that same system works well but often the economics are different:
• Ceilings are often left exposed, limiting the ability to use bottom side resilient materials and insulation.
Flooring Underlayment
• Recycled rubber mat under hard flooring provides the top of a noise control system designed according to “MASS-SPRING-MASS” physics.
• The recycled rubber mat is the spring and isolation device.
• The engineered wood or tile is the top mass.
• The gypsum concrete is the bottom mass.
Top Side Foundation
• Gypsum concrete provides the foundation of a top side noise control
system designed according to “MASS-SPRING-MASS” physics.
• An Entangled Net is the spring and isolation device.
• The joist assembly is the bottom Mass.
