Casement & Awning Windows


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 for a total sash thickness of 1¾” or 2¼”. Traditional European in-swing and American out-swing operation is available. These windows are also available in contemporary aluminum or bronze clad.

Out-Swing
Our out-swing casement window is operated by using a bronze push bar or a high quality roto-operator with cover variations. The operable sash is assembled with mortise and tenon joinery and is supported by European exterior “screw-in” hinges or concealed stainless steel hinges. To keep the elements on the outside, the sash is sealed with two uninterrupted weather seals and has a machined-in water channel at the top and sides.

In-Swing
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 bronze 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.

We also use the latest technology for our insulated glass spacer bars to ensure minimal heat transfer and dramatically reduce condensation.

Hardware

Grabill provides premier custom hardware for casement and awning windows.

Multi-point lock options with your choice of levers and trim, traditional push bar operators or roto operators are available. We offer an extensive line of hardware including solid bronze pivot hinges and latches with custom finishes. Specialty hardware including motorized acuators per project requirements.

Finish

Wood finishes can be shop primed, painted, or stained to your specifications with samples provided for final approval. Custom rustic aged, bleached, or antique finishes are also an option.

Grabill uses low *VOC emission paint products, when ever possible, which contain little or no toxins that pollute indoor air, and are water or latex based to decrease hazardous fumes and waste.



Screen / Storm

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.
