Apex’s Vacuum Bag Technology is used to create every Apex Board. It is an advanced construction process used to maximize strength and eliminate weight. The theory behind the technology is to pack as much fiber into the board and remove as much resin as possible. The board’s fiberglass material is compacted with three to four tons of force. Meanwhile, dedicated vacuum channels extract excess resin directly from the board during the curing process. This process is so effective that the board can have additional fiber reinforcement without any weight penalty. This is how APEX boards are the strongest and the lightest.
