About Us


The R. Lang Company manufactures the TRU-FRAME® GREENHOUSE WINDOW.

The R. Lang Company was established in the fall of 1967, when Richard Lang purchased the Roll-Away screen and fabricated special products division from the Rudiger-Lang Company and located the business in a small 7500 square foot building in Richmond, CA (near San Francisco).

Today, R. Lang Company occupies over 80,000 square feet of office and plant space in two locations and employs over 100 people.

The TRU-FRAME product line consists of several fabricated products, which include screen doors, storm doors, security screen doors, sliding screen doors, screen frames and components, skylights, and Roll-Away® window screens and doors. Roll-Away® is a unique screen product that retracts into a housing and may be viewed by visiting our other website at www.Rollaway.com.
