Energy efficiency


Thermal performance has always been prioritized. Our highest rated fenestration offers an R value of approximately 11, thereby exceeding levels set by ASTM and AAMA specifications.



Sorpetaler provides extremely fast lead times compared with other custom millwork shops foreign or domestic. Manufacture is typically 5‐7 weeks. Shipping to the East coast adds 3 weeks; to the West coast 5‐6 weeks.



Customers have access to Sorpetaler‐trained installation crews.



Our engineering support crew has decades of custom millwork and engineering experience and can provide project based engineering guidance.

Environmental Stewardship


Sorpetaler has promoted FSC certified woods since their inception in the 1990s. Sorpetaler sources timber from responsibly managed forest lands, is a net producer of wood briquettes from wood waste, and continually monitors alternate species and technologies that leave the lightest footprint for our heirs.

Low Carbon Footprint


Though imported from Germany, our carbon footprint simulates a car trip from New York to Minnesota.
