Endurex 520
Product Description
The Endurex 500 Series provides energy savings while enhancing the life and the aesthetics of your building exterior.

The Endurex 520 is the most traditional 1" insulated panel using tempered hardboard as stabilizers around a 2lb EPS foam core. Although still specified, the Endurex 520 panel does not offer the moisture and impact resistance found in the Endurex 500 and 555.

Endurex 520 is Class "A" Fire-Rated and carries a limited 5-year warranty with the standard Polyester Paint Finish in either smooth or embossed aluminum. Endurex 520 panels are manufactured to meet the requirements of a standard 1" insulated glazing panel. Panel thickness is available from as thin as 7/8" to 4" thick.

Endurex 520 insulated panels provide energy saving, long lasting beauty for the exterior of your building or store-front.
Hardboard Stabilizer
Click for enlarged view
Traditional stabilizer prior to the advent of next generation plastic stabilizers. Hardboard is an engineered wood product with good rigidity and impact resistance. Not the ideal choice if moisture absorption may be a concern.

A 1/2" or 5/8" gypsum stabilizer can be substituted for the hardboard stabilizer on the innerside of the panel, if desired.

Insulation Options
From economical standard 2lb EPS foam to fire retardant PolyIsoCyanurate Foam, the Endurex 520 panel can be configured to provide insulating values to an R-30.
