Arctic Infill Backpans
The Arctic Backpan is essential to a spandrel glazing project.
In this type of project, the overall curtain-wall assembly requires higher R-Values.
The standard four inch Backpan gives an R-Value of 26. This can be raised even higher when coupled with Arctic Infills.
Arctic Backpans can be finished on the interior as well, to match the mullions.
