KS42 Micro-Rib |
 |
APPLICATIONS:
KS42 Micro-Rib insulated panels for Industrial/Architectural applications
provide designers with a wide range of practical and aesthetically
pleasing design flexibilities. The superior, engineered joint assures
a tight, well designed vapor barrier and building envelope, in either
horizontal or vertical application.
CONSTRUCTION:
KS42 Micro-Rib panels are constructed with a non-CFC thermosetting polyurethane
insulation that meets US and Canadian building code requirements. 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:
KS42 Micro-Rib panels with polyurethane insulation are offered in thicknesses
of 2”, 2-1/2”, 3”, 4”, 5" & 6" providing the highest
R-value of any commonly available insulation product.
FACINGS:
KS42 Micro-Rib panels have a standard 26 gauge face of smooth or stucco
embossed galvanized steel to ASTM A653 G-90 or galvalume designation.
The base steel is a structural quality to minimum Grade “A” 33
ksi, conforming to ASTM A924. Optional panel facings of stainless steel
are available on request in various gauges.
COATING SYSTEMS:
Standard KS42 Micro-Rib panels coating systems include “Kynar 500” PVF2
finish with high performance properties and a 20 year manufacturers’ warranty,
covering color retention, chalk resistance and film integrity. Silicone
modified polyester (SMP), polyester and plastisol finish coatings also
offer outstanding performance.
PANEL DESIGN:
KS42 Micro-Rib panels utilize a superior joint design with a hidden fastener
anchorage affording connection of both metal skins to the building
structure, and a caulked seal provision that provides excellent air
infiltration and water penetration test results. Panels are available
in Micro-Rib profile on the exterior face and Shadowline stucco embossed
profile on the interior face.
Panel coverage is available in standard 42" width. 24", 30" & 36" are optional
