Freedom Step® Subfloor Panels - Acoustical Floor Panels
Martial Arts Floors
Freedom Step® Subfloor Panels for acoustic and sprung floor applications.
Freedom Step® Subfloor Panels serve a wide variety of applications where the absorption of impact and sound isolation are required. Freedom Step® Subfloor Panels and Freedom Step® Pro Subfloor Panels are an engineered floating floor system that allows multi-use buildings to function by mitigating structure borne sound transfer. Floor impact isolation is required for applications such as ‘free weight drop’ and ‘treadmill noise’ in health clubs, ‘heavy floor impact’ for activities such as ‘dance studios’, ‘martial arts’, or ‘aerobics classes’.
Freedom Step® Subfloor Panels are ready to be installed right off the skid and do not require any special tools or training. The Tongue and Groove panels are simply tapped together using a hammer and spare piece of wood. It is recommended that they are installed in a ‘brick’ pattern for the greatest stability followed by an overlay of plywood with joints staggered to the Freedom Step® Subfloor Panels. For dance floors use a ‘good one side’ ½” plywood to retain the maximum resilience. For commercial gyms use minimum 5/8” or ¾” plywood before the gym floor finish for impact resistance. Concrete toppings can be poured over Freedom Step – Please consult factory for loadings.
Freedom Step® Subfloor Panels System has the highest acoustic isolation available of any floating floor in the world. Key to its performance are the ‘diamond shaped isolators’ that consist of conical multi pointed ‘compressible elastomer’ absorption pads and surrounded by acoustic media, that are pre-attached to nominal 2’x 2’ Tongue and Groove panels for fast and easy installation.
Acoustic performance is measured in an ASTM recognized testing method for IIC (Impact Isolation Class). The improvement is reported as Delta IIC. Lab Tested on a 6” concrete slab the Freedom Step System has the following acoustic performance.
Freedom Step® Subfloor Panels 1-5/8” overall thickness – Delta 35 improvement
Freedom Step® Pro Subfloor Panels – 2-5/8” overall thickness – Delta 44 improvement with significant low frequency benefits.
