Rebonded foam having multi-directional strength. Robbins’ system provides a continuous resilient blanket, Aegis Treatment, and multidirectional cell strength. Robbins' material is 100% recycled. Connor’s pad is a much higher density material. Another layer of 11/32” plywood Anchoring method Bio-Channel VP anchors use a metal hat channel to allow lateral movement in the system. Panels are spot riveted together 3 times per panel Exact type is not known. Metal hold down – Rivet style subfloor panel connectors Not Equal Robbins BioChannel VP is Superior The Bio-Channel VP subfloor system will provide the ability of lateral movement to slide during the seasonal changes. The Connor system does not have this. The Robbins system will have more hold downs per square foot.

Equal Same products or equivalent Anchor Frequency With 4 anchors per subfloor panel each anchor secures 4 square feet. This system does provide lateral movement in the subfloor VIP subfloor sections have 1 anchors every 5.55square feet. The system does not provide lateral movement in the subfloor. Not Equal Robbins factory slotted Bio-Channel VP subfloor made with 23/32" CDX plywood installed diagonally to the finished flooring (16 sq. ft. per panel). No plywood seams parallel maple for added systems strength. 1 layer of 11/32” thickness plywood installed perpendicular to the flooring. Plywood orientation produces common seams between flooring boards and plywood subfloor. The plywood is gapped 1” along the 8’ seam. Not Equal The Bio-Channel VP system is anchored more per square foot and provides lateral movement. Both features deliver a system with better uniformity over time. The Bio-Channel Star system is laid on a 45 degree angle. Eliminates common seams, increases uniformity of performance and uniformity of loading strength. Perpendicular placement of the subfloor panels creates common seams resulting in non-uniformity in system game-play characteristics and strength. 25/32” x 2 ¼”, 2nd & Btr.

Less wood is removed during sanding leaving more wear surface for the owners, i.e., more life. Factory-sanded material means there is even less wood removed during field preparation adding life to the floor and virtually eliminates sanding dust during installation for a healthier facility.
