Zola Windows

A new high-performance simulated double-hung window from Zola Windows has been engineered for historic building renovations and provides authentic style alongside airtightness and thermal performance, the company says.

Adaptive reuse of historic buildings is a popular choice for developers looking to create unique communities. But in renovating older structures into new mixed-use and multifamily housing projects, architects and builders may struggle to marry modern concerns, such as energy efficiency, with preservation of the buildings’ original architecture

Incorporating a Zola Tilt & Turn lower window and a fixed upper half, the American Heritage SDH provides tight seals and easy operation while maintaining the style of a traditional double-hung window. The replica-quality window also uses offset glass panes to create the shadow line characteristic of the style.

Using R-11 glass and three compression gaskets, the window provides thermal and efficiency performance suitable for high-performance retrofits, including the Passive House standard.

The all-wood window is offered in FSC-certified varietals that include pine, oak, and meranti. Low-iron European glass is used for superior acoustic performance; Zola also offers the window with custom asymmetrical glazing to provide additional sound deadening qualities.

American Heritage SDH windows feature German-engineered hardware in a number of finishes, or buyers can select solid brass custom handles for an additional charge. Concealed hinges, marine-grade hardware, and silver plating are also available.

As part of Zola’s Historic Series, customers can also work with the company to custom-design a complementary entrance door for their building.
