From Gerkin’s beginning in 1932, their primary focus has been to manufacture energy saving window and door products. Throughout their history they have established ourselves as an innovator in the design and manufacturing capability of insulated windows and doors.
Stringent product testing and innovative design has allowed their products to evolve as market and consumer needs change. In the winter of 1989-90 they started to conceptualize and design their Rhino Commercial Aluminum window and door series. Today they have several commercial window styles and doors in the Rhino line. This window and door series consists of a commercial horizontal slider, casement, single hung, double hung, hopper, awning, fixed and patio door. Each Rhino window reflects the design and manufacturing expertise they’ve implemented over the years. They also publish our AAMA test results to back up their claims of product performance and quality.
