Zola's American Heritage SDH™
A replica-quality tribute to the historic double hung window, our Simulated Double Hung (SDH™) windows are ideal for historic Passive House retrofits. Increased energy efficiency and minimized external noise are just two of the many advantages while maintaining the look of a historic double hung.
American Heritage SDH™
Our SDH™ Simulated Double Hung windows feature concealed multipoint hardware, double or triple glazing, and R-7 performance overall (triple glazed option). With outstanding thermal and acoustic performance, modern functionality, and the style and proportions of a traditional double hung window they're perfect for historic retrofits.
American Heritage SLIM SDH™
Our SLIM SDH™ Simulated Double Hung windows feature all of the same incredible qualities as our standard SDH™ offering, but with reduced profile width. This results in a more minimal presence while still offering a traditional double hung appearance.
Zola's Wood Lines
Our Classic Wood™ and Thermo Wood™ lines optimize the natural qualities of wood to maximize both beauty and performance.
Thermo Wood™
Zola Thermo Wood™ is a classic choice for high performance homes. With R-11 glass standard in an industry-leading 18mm spacer thickness, Thermo Wood can be offered in extremely large sizes.
Classic Wood™
Offered in the highly durable Meranti Wood, Zola’s Classic Wood™ line comes with a double pane and versatile array of staining options. The choice for beautiful projects seeking the sophistication and natural appeal of wood, this line is still more energy efficient than typical American window and door designs.
An Experience You Can Rely On
I’ve been most impressed with our whole Zola experience from sales, ordering and now to delivery and on-site support. Congratulations on assembling such a professional team and making what is typically a complicated and challenging process run so smoothly. As a self-styled ‘window aficionado’ I can’t tell you how happy that makes me.
