About American Heritage SDH™ Windows

American Heritage SDH™ windows combine a lower tilt & turn assembly with a fixed upper to provide outstanding thermal and acoustic performance, modern functionality, and the style and proportions of a traditional double hung window.

American Heritage SDH™ has been approved by many historic preservation commissions, including Brooklyn and Manhattan commissions. The window features concealed multipoint hardware, double or triple glazing, and R-7 performance overall (triple glazed option).

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.
