APPLICATIONS:

Industrial / Architectural applications provide designers with a wide range of practical and aesthetically pleasing design flexibilities. The superior joint engineering assures a tight, well designed, building envelope.

CONSTRUCTION:

THERMAWALL 4000 SERIES PANELS are insulated with a NON CFC thermo-setting polyurethane insulation that meets most model building code specifications. Structural grade steel facings are precisely roll formed and foam insulation is expanded between the metal sheets in a state-of-the-art continuous line production sequence that is fully computerized to ensure optimum quality and consistency in every panel.

INSULATION:

THERMAWALL 4000 SERIES PANELS with foamed polyurethane insulation are offered in a thickness range of 2" to 4", providing insulation values of R-15 to R-31.

FACINGS:

THERMAWALL 4000 SERIES PANELS have standard 26 gauge facings of smooth or stucco embossed galvanized steel to ASTM A-525 G-90 designation. Base steel shall be structural quality to minimum Grade “A” 33,000 PSI, conforming to ASTM A-446. Optional panel facings of galvalume, aluminum or stainless steel are available on request in various gauges.

COATING SYSTEMS:

CBS Coating Systems include “Kynar 500” PVF2 finishes with high performance properties and a 20 year warranty, covering color retention, chalk resistance and film integrity. Silicone modified polyester (SMP), polyester and plastisol finish coatings also offer outstanding performance and extended warranties.

PANEL DESIGN

The THERMAWALL 4000 SERIES PANEL utilizes a superior joint design providing concealed fastener anchorage affording connection of both metal skins to the building structure, double caulk seal provision and excellent air and water infiltration test results. Panels are available in “SHADOW LINE” and “LINEAR FACE” Profiles.

Panel coverage is available in 30", 36" 42" widths.
