Ampex panels have unique “mushroom” shaped nubs which locks the PEX tubing firmly in place (staples and zip ties not needed). The 2x4’ (610x1220mm) panels are light and manageable improving maneuverability in tight spaces and damage on site. The nub height and film accommodate multiple tube sizes and protects the tubing from damage and dislocation when the panel is walked upon by other trades. The large, four-sided interlocking shiplap connector system makes for a quick, easy and secure installation while maintaining the continuity of the vapor barrier and eliminating the need for a dedicated 6 mil. polyethylene (unless specifically required by local building code).
