Manufactured in Galvanized G90 (standard) or Galvalume steel in 20, 22, or 24 gauge thicknesses. These corrosion-resistant materials balance structural strength, lightweight handling, and long-term durability for demanding exterior environments.

Unitized systems are considered to be superior from lower on-site labour costs derived from the units being manufactured in a climate-controlled factory environment and shipped to the site in modular units.
Stick-built systems can be more economical especially if the building facades require lower volumes. In addition, the lead time is much shorter. The parts required will be ready which will then allow for earlier installations. However, the installation will take longer because fabrication and glazing will be done on site.
IMARK uses Roxul Cavityrock exterior cavity insulation which has been designed exclusively for the use in exterior cavity wall and rainscreen applications like back pans. As a high density semi rigid board Roxul Cavityrock insulation combines a high density outer layer and softer inner layer that is fire resistant, water and moisture resistant and delivers a R-value of 4.3/inch.
Depending upon the back pan design and depth of the pan we can supply insulation in thicknesses ranging from 2″ to 5″ (3″ standard)

Back pans are designed to minimize field installation time and can be fastened to curtain wall, steel substrate or block substrate. Specialized shapes and custom punching or notching are available to suit any specific application. All corners of our back pans are tabbed sealed and spot welded to deliver superior performance as a vapor barrier. IMARK is also experienced in fabricating Hilti Firestop back pans for use in unitized curtain wall assemblies.
