The ThermaPlank™ commercial entry doors are designed using the same structural integrity as our FL-400 flush door design with the added benefit of being thermally broken. The unique flush plank door design uses 4” interlocking extrusions with Polymide 66 thermal struts to improve the thermal properties of the door without compromising strength.
These Miami-Dade approved commercial entry doors are structurally sound as well as flexible in their design. It is not uncommon for these doors to have different patterns and/or colors from the interior and exterior of the building. The dual finish design allows for architects and design professionals to offer more options to their customers.
