Back Pans

Products

Back Pans

These are generally used in curtain wall systems, either behind a metal panel or on the back of spandrel glass. They provide excellent insulation, fire safety and sound absorption capabilities. Yarlmetal produces back pans of various shapes and sizes; the most common ones are rectangular bases with straight clips. Special adapters are formed at the end of the clip to suit the installation.

Each adapter is utilized for specific needs and requirements. For more information, please contact the sales department The above items refer to the different variables that are taken into consideration in designing backpans and they can be adapted in various ways to produce customized back pans to fit every space and requirement.

What we can Do?

Design Consideration

The following variables are taken into account in determining the profile of the backpans

  • The sectional depths of the curtain wall and window influence the pan depth.
  • Most common insulation has "R" value 4/ inch Thickness of insulation will vary depending on the R factor, type of insulation and pan depth.
  • The profile of the back pan depends on how the glass is installed.
  • The back pan material is selected based on the finish specifications.
  • Width and height of the pan are in most cases ¼ inches less DLO (Day Light Opening).
Size & Shape
Pan Size may be any size virtually in level with the vertical wall. To accommodate large sizes, smaller pans are joined together and intermittently reinforced using vertical legs There are also several types of shape for the base of the back pan such as trapezoidal, rectangular, triangular, semicircle and many others. These custom-made insulated pans can be made to fit into any space. 45-degree angle pans to accommodate building corners, and corresponding clips with a slight angle are made to act as a drip to keep moisture from entering the building.
Profile
The angle on the clip is formed to contain caulking to seal the joint between the pan and the curtainwall. All different profiles shown of the sketch are based on design needs.
Material
Most commonly used is 20 gauge and seldom 22 gauge galvanized steel. However, they can be made of any gauge steel depending upon the requirements of the client.
Insulation
The type of insulation used in the back pan is critical to the effectiveness of the pan. The effectiveness of the insulation is measured by the R-Value, which expresses the amount of heat that is kept within the system. A higher R-Value allows less heat loss through the layer. The most commonly used insulation is Roxul RHF 40, which has an R-Value of 4.2, but other options are available.
