"Working with Zola Windows has been a stunningly positive experience. Zola offers vastly superior service and responsiveness over any other window provider I have worked with. The price is feasible, the windows are stunning, and the performance is everything a Certified Passive House consultant could hope for, not to mention the color options that come standard, it's enough to make an architect's heart sing…"Tessa Smith,

"We love our Zola windows…that really is the truth…we cannot buy windows that have this quality for this price made in the States and we think they add great value to the project."Laura Nettleton,

Zola offers a wide selection of hardware options to match your style. Our standard handles are aluminum handles with a metallic finish of your choice. Many customers upgrade to our modern stainless steel handle or our timeless chrome handle. For the very finest selection, consider our Zolini handles. These hand crafted handles are made in Italy, of finest Bronze cast in a traditional mold. Designs span from classic to modern, and finishes can be rubbed (a customer favorite), plated in real silver, or aged. The Zolini designs shown here are only a small selection of what is available. In fact, you can even design your own handles and we create a mold for you.
Zola strongly recommends concealed (hidden) hinges for tilt&turn windows. If 180 degrees of opening angle are required, we need to use classic hinges with a plastic hinge cap. For very large openings, typically over 28sqft, a heavy duty hinge system ,as shown, is required. This hinge does not utilize hinge caps and is crafted from metal in a modern design, available in silver only.
On doors, we typically use three to four hinges, hinge caps allow you to adjust the color to match your decor. Stainless steel hinges or hidden hinges for doors are available on request.
Divided lites and simulated divided lites
Zola offer a wide variety of simulated and actual divided lites. True divided lites separate the glass. Simulated divided lites do not actually divide the glass, but are a glued on bar on the inside and outside (in the case of an aluminum clad window, it would be an aluminum profile on the outside and a wood profile from the inside) as well as a spacerbar between the glass panes, giving the illusion of a true divided lite. This is the most common option. Note that in some high altitude locations and window sizes the spacer bars have to be omitted.
Divided lites, whether true or simulated, add significant cost to your window package, depending on frequency and layout. Cost increases of 30% are not uncommon. Consider using less or no divided lites and enjoy an uninterrupted view out of your window. A lower cost alternative is to use stick on bars (same as divided lite bars but without the spacer) or dividing bars solely between the glass panes, however, these solutions do not look as good as true or simulated divided lites.
For Tilt & Turn windows, we recommend our snap in, aluminum framed screens. The frame will be color matched to your cladding (it is shown in white in the picture for clarity), and the corners are miter cut and precision jointed, eliminating plastic connectors that break easily. The screen is easy to remove in winter from the inside. Seen from the inside, the screen frame does not impede on the glass area, except in the Panoramic View line of windows. For the screen mesh we use Phifer UltraVue, the clearest mesh we can find on the market today.
For single or double swing doors we recommend either our roll-to-the -side or pleated screen system. The pleated system is more expensive, but preferred by most customers, because the threshold added to guide the screen is only approximately 5/16″ high, and the look matches the lift slide pleated screen better. Because either system stashes to the side, you never need to see the screen mesh when you don’t need it, which makes these screens much more desirable than a screen door.
For Lift and Slide doors we can also offer our factory fitted rolling screen frames. These frames are the size of a door panel, and roll over the fixed part of the sliding door when not in use. The screen mesh is Phifer Ultravue, the clearest mesh we can find on the market today. If you prefer to not see your screen mesh unless it is in use, we instead recommend our pleated or electrically operated roll down screen detailed below.
The pleated screen system for Lift and Slide doors, BreezepanelTM folding wall systems, and large swing doors. This pleated screen can be up to 11′ high, and stows in a small pocket to the side. Up to 16′ of screen can disappear into one side, allowing for a total of 32′ of opening if screens are stowed both to the left and right. These screens are fitted by our technicians after install. Purchase of a Zola Tech service visit with your window package is required if you opt for these screens. Smaller lift slide or Breezepanel openings that are up to 8′ high and 10′ wide are shipped pre-mounted and feature a low profile, 5/16″ threshold.
The electrically operated, Zola roll down screen provides utmost luxury and flexibility. The screen can be up to 10’6″ high and 15′ wide, and the frame pieces will be color matched to your window. When ordered at the time of placing your window order, these screens can be installed on your window units at the factory (please note that oversized doors that ship as knock-down kits may require partial assembly of the screen system as well).
Safety glazing refers to glass that minimizes bodily injury in the case of breakage. This can be achieved by either tempering glass, or laminating glass. Tempered glass is incredibly strong, and if it breaks, breaks into thousands of small crumbles. A good example of tempered glass are the side windows of a car. Laminated glass consists of several sheets of glass, glued togehter with a plastic film in between. If broken, it shatters but stays in place (think windshield of a car). As a standard, Zola recommends and uses tempered glass where required. In a safety glass package, all panes must be tempered or laminated.
Your home should be your sanctuary. Our high quality, European-manufactured glass and triple sealed frames provide a level of sound dampening of outdoor noise pollution that is exceptional on the North American market. Noise mitigation is particularly important inbuildings near busy streets or highways, train stations, and airports. Whether you are concerned with minor sound dampening or you live in an urban environment where the highest acoustical performance is required, we are sure to have a glass solution that fits your needs.
We use asymmetrical glass assemblies containing one or more laminated glass panes to tailor the sound dampening to your needs.
Security in windows and doors against break ins requires strong hardware and burglar resistant glass. Even our standard multi point locking packages are no match for most thieves, but we can upgrade your window packages with even more locking points and highly crowbar resistant interlocking hardware assemblies at a low upcharge. Glazing can also be customized to prevent break ins and many types are tested to withstand specific tools or even firearms.
