A composite material may be used as a building material to provide desirable visible aesthetics, such as in a roof or facade. The composite material may include two or more materials, wherein a first material provides desirable qualities for appearance and a second material provides desirable qualities for strength or other characteristics desirable of a building material. Each of the first material and the second material may be transparent, such that the composite material is also transparent. The first material may be Ethylene tetrafluoroethylene (ETFE) and the second material may be Polyethylene terephthalate (PET).
