Curtainwall Systems
Unitized Curtain Wall Systems
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 Curtain Wall
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.
Design
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.
