See Product Details

ZIRCEM-11 is highly damageresistant, non-corroding, and extremely water-resistant. ZIRCEM-11 is available in full size 4' x 8' panels which offer major economic advantages in the construction of ovens, dryers, and other insulated housings for the retention and control of heat. ZIRCEM-11 can be readily fabricated into various sizes and shapes for heat baffles and all types of insulating parts.

ZIRCEM-11 is not affected by moisture or high humidity, and will not rust, rot or corrode. The panels will not

disintegrate even after prolonged immersion in water. While the material can be painted if desired, preservative treatments are not required for interior applications.

ZIRCEM-11 is hygroscopic and electrical resistance is reduced when it absorbs moisture. For electrical

applications, ZIRCEM-11 components should be thoroughly dried or moisture proofed before use.

ZIRCEM-11 is monolithic That is oven dried, so it machines into exceptionally fine and intricate parts without

delamination. The board is neutral gray in color, and may lighten uniformly with time. ZIRCEM-11 requires practically no maintenance. The hard, smooth surface does not normally need painting or preservative treatment, but either can be applied if a different aesthetic appearance is desired.

Installation Details

ZIRCEM-11 can be applied directly to framing members with screws, bolts or mechanical fasteners. The board is recommended for interior applications only. All bolts or fasteners must be placed in predrilled oversized holes no closer than 1/2" from any edge. Oversized holes must be 1/16" or larger diameter for 1/4" bolts and 1/8" or larger diameter for 1/2" or larger fasteners. Bolt heads and nuts must have an adequate washer bearing surface. Applications where vibration or motion exists must utilize rubber or neoprene gasketed washers.

ZIRCEM-11 should be stored horizontally in a dry, flat area.
