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.

Options To Fit Your Home

Our library of custom options will ensure that your windows and doors match your home’s architecture interior design.

Wood Species

Finger-Jointed Pine is our standard option. For upgraded wood options we offer Clear Pine, Meranti, Fir, European Oak, and Larch.

Pine, Clear

Clear pine has a beautiful, smooth and knot-free appearance. Versatile for high value carpentry, especially trim work and frames.

Oak

A classic wood, Oak is used in broad applications, particularly in fine furniture.

Meranti

A straight-grained hardwood, Meranti is valued as veneer, trim, and framing.

Pine, Finger-Jointed

Finger-jointed pine uses a woodworking joint made of sets of “fingers” cut into two pieces of wood which then interlock.

Fir

One of the world’s best know wood species, Fir is prized for its straight, fine-grained wood.

Larch

Larch is a straight-grained timber with very tight growth rings.

Wood Stains

Zola ships all windows fully finished, either stained or painted, for a superior, even, and durable finish. The stains shown here are Zola’s most popular, but represent a small subset of the full catalog of stains available.
