AMPEX 2020FK residential/light commercial insulation R10 - 45 psi panels (64 sq. ft.) are used for radiant floor (slab) heating systems both for interior and exterior applications - including exterior snow melt systems. The combination of molded expanded polystyrene (EPS) insulation with a vacuum applied high impact polystyrene (hips) film lower face， makes for a strong and resilient panel. The panel combines rigid insulation， a vapor barrier and a pipe locking mechanism into a single solution， that significantly reduces installation time and labor.- Ideal for installation in residential basements， patios， sidewalks， workshops and livestock barns， any concrete slab that will not have vehicles or heavy equipment used on it. They are also available in a wide range of other compressive strengths and thermal resistance values to meet the needs of most projects.

Panel design ensures that the tubing is completely encased in concrete and not pushed to the bottom of the panel through the use of bridge connectors and the larger contact area between the tubing and the concrete allows for efficient heat transfer

Oversized 4-sided tongue and groove interlock system makes for quick， easy and secure installation unique patented design of the panel nubs will accept any certified radiant heating pipe sizes of 3/8 in. to 1 in.

Nub height and film accommodates tube sizes from 3/8 in. to 1 in. O/D and protects the tubing from damage and dislocation when the panel is walked upon during construction， no staples and zip ties greatly reducing install time

Provides for efficient alternative heating in new construction and renovations， T and G edge connector system makes for a quick， easy and secure installation with continuity of a class II vapor barrier
