Since 1932, our primary focus has been to manufacture energy-saving window and door products. In 1989, we started to conceptualize and design our Rhino Commercial Aluminum window and door series. Today, we have several commercial window styles in the Rhino line. We are one of the few commercial aluminum window companies that offers a product line diverse enough to supply windows for schools, medical clinics, offices, motels, strip malls, loft apartments, and modern homes.
Gerkin has long been known for making one of the tightest horizontal sliders on the market. While many competitors hide their air infiltration rates, Gerkin touts a rate that is over 400% better than architectural standards.
The 5100 awning windows have been popular for high-end condo projects as well as many municipal and office buildings.
The 5200 Rhino hopper window (projects light in) is ideal for single or multi-story commercial projects. This window features a 2 3/8" thermally broken frame depth, reinforced power-crimped sash corners, and a sash that overlaps the frame.
Gerkin 5300 casement windows are designed with performance in mind. The air infiltration on our casement is often better than our competitors’ fixed windows.
The 5500 fixed windows are designed with performance in mind. These windows perform so well in NFRC thermal tests that they have been used in 5-Star Green Build projects, Net Zero housing, and in numerous LEED certified projects.
The 5800 Double Hung window was tested to be used in sizes up to 60" x 99". The air infiltration rate is an amazing .03!
Gerkin's 58F series offers a great alternative to storefront systems. Gerkin has designed this window to look like storefront but offer superior thermal performance, water resistance, and air infiltration.
This single hung offers great performance with a smooth operation. The 5900 is highlighted by block and tackle balances, tilt-in sash, recessed tilt latches, automatic sill locks and dual pull rails! Our air infiltration is an amazingly low .03!
The new model 5400 sliding patio door is a great product for the commercial market as well as for the modern home design market. We offer a 2-lite style with sizes up to 8' x 8'.
