Zola's ThermoPlus Clad is our best selling window, engineered for the Passive House market. Based on the Zola Thermo Clad, the ThermoPlus Clad series adds a fully integrated layer of patented German Purenit® insulation in the frame and sash. The result is a window that boasts excellent performance (like an overall U-value of only 0.123 BTU/hr.ft2) while maintaining a sleek, elegant appearance and a highly competitive price in its class.

Zola's Classic Wood window. The standard wood window in Germany, Switzerland and Austria features a 68mm (2 3/4") Meranti wood frame and European high performance double glazing. The frame is fully factory finished in paint or stain to ensure longevity and beauty.
Classic Wood can also be milled to in our beautiful Heritage line to match the style of historic buildings.
Zola's Thermo uPVC is the lowest cost high performance window available. Made with the same high performance triple glazing as the rest of Zola's Thermo line, but at a 25% lower cost than the wood version. The uPVC frames come standard in white, but can be finished in a solid color or wood look for an additional charge.
Making Zola a Successful Part of Your Project
With a few tricks, Zola can be more economical, less hassle, and better performing – read why:
Tilt & Turn units can be up to 25ft2 per sash, with a max width of 5ft. Our 5'x5' Tilt&Turn is a bestseller. A French Tilt&Turn window, with two leaves, could be 10' wide and 5' high, or 6' wide and 8' high.
Fixed windows can be 8'x10' per glass pane in our standard system. Bigger is possible, but carries a price premium.
For doors, read on under "Doors ad Sliders"
So what does this mean to your design? If the budget is tight, combine smaller windows into less, larger ones. One 5'x5' Tilt&Turn can make a bedroom great. If it shall be spectacular, add a large fixed pane.
If your design is modern, less divisions and frames in the way will make it even more striking.
For openings from 7' to 11', many architects opt for an OX Tilt-Slide unit. A great air seal and the option o using the tilt function for night ventilation make this unit successful.
Lift-Slide doors are the most luxurious of sliding doors, and especially suited for large openings over twelve feet. Each glass pane can be up to ten feet wide, allowing us to build 20' OX units. A large part of the cost is in the hardware and assembly, making large lift-slides not much more than small ones.
Breeze Panels, our folding glass walls, are a good choice for any opening width from 7' to 25'. Cost is proportional to width for Breeze Panels.
Zola's sister business in Germany sells 90% wood windows, while Zola sells over 90% clad windows in the U.S.
From a cost standpoint, all wood units, even when made from Meranti, are much more affordable – the clad surcharge is about 35% in the classic line and 20% in the Thermo line.
We have built windows with a succession of curves, basket arches, trapezoids – just send us a precise CAD-file or full scale template.
For window units that need to achieve the look of a classic double hung, we recommend using one large tilt&turn window with a true glass dividing bar across the center, and additional munitions as needed for the design.
Our production time is eight weeks after we receive your deposit, plus shipping time by container, which will be three to five weeks to the lower 48.
It is highly recommended to submit your order to us by the time you break ground on your project.

Sliding Doors and Breeze Panels
There is more than one way to glaze a big opening.
Lift-Slides lift out of their seals at the turn of the handle, and the slide effortlessly with just a few fingers. They feature a very low threshold that can be embedded into the floor.
Balcony, Terrace and Entrance Doors
Note that for the main entrance door to any unit you need to specify an entrance door, which is our strongest type of door and built for the heavy use as a main door.
