Imagination Millwork’s Decorative Faux Windows are skillfully crafted from sustainable PVC and resilient black plexiglass. The frame, trim (moulding), grilles, and keys are all constructed from durable white PVC. The faux "glass" is an opaque black plexiglass. Imagination Millwork’s Decorative Faux Windows can be installed on virtually any exterior surface and are designed so they will not pierce the building envelope*. Decorative Faux Windows require no assembly and are shipped ready-to-install. Imagination Millwork does not stock Decorative Faux Windows as they are built-to-order and manufactured at the time of purchase. *A building envelope, or environmental separator as it is sometimes referred to, is the physical separator between the interior and exterior of a building (i.e. wall or roof). It provides thermal comfort and protection from the elements, including the resistance to air, water, heat, light, and noise transfer.
