Double Hung Windows


Grabill offers historically accurate single, double and triple hung windows with weight and pulley, concealed spring balance operation or single glazed unbalanced sash with spring bolts. Our high quality brass pulleys can support the sash using bronze / stainless steel chain or traditional cotton sash cord.

Our joint matched true divided lite muntin bars are standard and can vary in width and depth according to the glass specifications. Our single / double hung windows are available in all-wood only.


Wood

Wood species are project specified. Grabill uses Smartwood FSC certified Genuine 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, Genuine Mahogany, Walnut, Sapele, Douglas Fir, Teak, White Oak, Ponderosa Pine, Eucalyptus, Cypress

Glass

Glass can be tinted, tempered, laminated, reflective, low E (with or without Argon Gas), high impact, obscured, security or as required. Silicone gaskets are used for weather-stripping which is proven to be flexible, long wearing, and impervious to the damaging effects of ultraviolet rays. Zinc or bronze metal or wool pile weather stripping is standard.

Hardware

At Grabill, premium hardware is essential. Stainless steel and architectural bronze hardware are standard with specified finish options including satin nickel and oil rubbed bronze. We also feature electric actuators for motorized windows which expands our capabilities and product range. We use traditional and contemporary operators. Architectural hardware selections include AGB, Hoppe, G-U, **Bronze Craft,  FFI or as specified.  All our hardware carries a lifetime warranty.

Our use of stainless steel components offers high resistance to corrosion even in coastal environments.

** Bronze Craft hardware is nearly 95% recycled and provided on our Eco-Choice window series.

Finish

Wood finishes can be primed only, painted or stained to your specifications with samples provided for final approval. Custom rustic and aged 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.

Most of our projects are completely finished in house prior to shipping. For painted products Grabill recommends a final paint coat after installation is complete to comply with Grabill Warranty.

*Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor presser under normal conditions to significantly vaporize and enter the atmosphere.

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. Grabill is pleased to include GORETM inLightenTM a window screen made with an ultra-fine material that makes it appear virtually invisible, bringing the outside in with a clearer view, better light and better ventilation.

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 quite 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.
