Backpan, also known as "spandrel", integrates seamlessly into the curtain wall, providing both thermal and acoustic insulation. Specialized shapes, as well as custom perforations or cuts, are available to meet specific application needs. Depending on project requirements, we offer insulation ranging from 1 to 8 inches thick. Our backpans include multiple standard types and shapes. In addition to our four standard models, we also offer custom variants, providing a more diverse range for building cladding.
