Casement & Awning

Grabill offers casement, awning and hopper windows in a variety of configurations which can be integrated with fixed in frame windows and doors. The operable sash is assembled with mortise and tenon joinery and clad with bronze extrusions, for a total sash thickness of 2 13/16”. To keep the elements on the outside, the sash is sealed with two uninterrupted weather seals and glazed with sealant placed in a dual durometer EPDM glazing gasket. European in-swing and American out-swing operation is available. These windows are also available in all-wood or aluminum clad.


Our traditional out-swing casement window is operated by using a bronze push bar or a high quality roto-operator. The operable sash is assembled with mortise and tenon joinery and is supported by European exterior “screw-in” hinges or concealed stainless steel hinges.


Our contemporary styled in-swing window is operated by a single lever, allowing the window to swing in like a door. Our stainless steel multi-point hardware system ensures a tight seal while providing additional security and increased sash stability for oversized units.

Insect screens are installed on the exterior as a fixed or retractable screen. The in-swing window is also available in all-wood or aluminum clad and is compatible with a wide selection of lever designs, from modern to rustic.

Since our in-swing casement systems do not have fixed vertical dividers between sashes, they are ideal for meeting egress requirements while still maintaining elegant sash proportions.

All of our bronze clad products are made from Grabill custom profiles with heavy gauge extruded metal that will last for generations and naturally oxidize over time without degrading the metal. Grabill custom patina and finish applications achieve various levels of Bronze Ageing and Antiquing without the wait.

    Wood species are project specified. Multiple wood and split species available. Grabill uses Smartwood FSC certified Mahogany and Eucalyptus and sustainable lumber when ever possible. Engineered Douglas Fir laminated cores are also FSC certified with low *VOC emissions. All of our lumber is kiln dried to a moisture content of 6-8% at the time of fabrication.

    Knotty Alder, Cherry, Spanish Cedar, Mahogany, Walnut, Sapele, Douglas Fir, Teak, White Oak, Ponderosa Pine, Eucalyptus, Cypress

    Grabill bronze clad windows combine the warmth and beauty of wood and naturally aged bronze. Bronze windows are durable and virtually maintenance free. Chemical patinas are hand rubbed, brushed, or polished to give an antique, aged appearance without the wait.

      Screen frames are fabricated from anodized aluminum or solid wood with various finish options.

      Screen cloth is available in fiberglass, aluminum or bronze wire mesh.

      Retractable Screen is a perfect option for standardized sizes. Screen slides into the natural recess of the door or window frame and virtually disappears when not in use. Screen hardware offers a smooth operation and when not in use the screens are protected from dirt, ultra violet light and inclement weather.

      Storm windows are a great match for restoration projects using single glazed windows. Screen/storm inserts use the same frame and interchange the screens and storms. Storm windows are made to order for restoration or single glazed window applications.

      Casements over 60 inches require double locking mechanism.
