Can SPD-Smart architectural windows be retrofitted with SPD-Smart windows?

Yes, any architectural window can be retrofitted with SPD-Smart windows. Just complete the “Project Inquiry Form” found in the main menu “Contact” section, to learn more about SPD-Smart architectural products. Be sure to indicate your interest is in retrofit installations.

What kinds of maintenance do SPD-Smart architectural products require?

SPD-Smart architectural products require very little maintenance. Their smooth glass or plastic surface accumulates very little dust and is easily cleaned. In addition, they have no moving parts which helps ensure reliable operation.

How do SPD-Smart architectural products help protect interiors and artwork from fading and degradation?

Interior furnishings and artwork can be highly susceptible to damage from excessive light-exposure. This damage is irreversible. SPD-Smart architectural products offer extraordinary protection in a number of ways. First, they block 99% of harmful UV light at all times. Fading and degradation also is caused by visible light, and SPD-Smart windows can block up to 99.5% of visible light in an instant. In addition, solar heat also causes fading and degradation. The variable tint property of SPD-Smart glazings allows for optimal protection of furnishings and artwork from visible light, and it also effectively manages the heat transferred through windows, offering even more protection.

What type of power is required to control SPD-Smart architectural products, and how much power do they consume?

SPD-Smart architectural products are controlled using AC voltage. Alternatively, DC power can be used to with conventional inverter (CHECK) integrated just before the SPD glazing. The power consumption of SPD-Smart products is nominal, and typically is just 0.06 watts per square foot when fully powered.

What types of fabrications are offered for SPD-Smart architectural products?

SPD-Smart single-panel laminates are ideal for interior partitions and doors such as those used in conference rooms and media centers. These laminates also are used for retrofits of existing windows in situations where advanced light-control is desired. For exterior glazing products, SPD-Smart architectural products also are offered in double- and triple-glazed fabrications for thermal efficiency.

How are SPD-Smart architectural products controlled?

There are many ways to control SPD-Smart architectural products. Most control systems involve a simple switch (similar to a dimmer switch for a light) or an on/off pushbutton. You can easily integrate these products with a home automation or building management system that uses occupancy sensors, photo sensors, and time-of-day controls.

Are SPD-Smart architectural products available in custom sizes, shapes and fabrications?

Indeed they are. SPD-Smart architectural products are available in sizes up to 1 meter wide and wider if pieces of SPD film as laminated side by side (i.e. “seamed”) within the laminate. Virtually any shape is available including circles, trapezoids and curves. Various fabrications are offered too. Laminates are ideal for interior partitions, while high-efficiency double- and triple-glazed insulating glass units are the energy efficiency choice for exterior windows, skylights and doors. In addition, these products are offered in conventional shapes and custom ones too, including curves.

Is there a more technical description of how SPD-Smart architectural windows control light?

The SPD film layer in SPD-Smart architectural products is called a “light valve.” Within the film are millions of microscopic particles. The particles are randomly oriented due to Brownian motion and absorb over 99% of visible light hitting the window. When an electrical voltage is applied, the particles align and light passes through the window. Adjusting the voltage adjusts the orientation of the particles, which regulates the tint of the glazing and the amount of light transmitted.

How do SPD-Smart architectural windows work?

SPD-Smart architectural products and needs to refer to marine/rail products.

Why are SPD-Smart architectural windows better than other types of window shades?

Conventional window shades are space-consuming, view-blocking, dust-collecting, prone to malfunction and do not adapt well to changing environmental conditions and user needs. SPD-Smart architectural windows, however, offer an unparalleled combination of form and function. As sleek as a standard window and just as easy to keep clean, these dynamic glazings provide shading and privacy, reduce glare, preserve views on-demand, block 99% of harmful UV light at all times, and can be controlled manually or automatically. Best of all, they are instantly responsive and infinitely tunable.

What makes SPD-Smart architectural products unique?

SPD-Smart architectural products are the fastest-switching variable tint products available today. You can change the tint of your SPD-Smart products in three seconds or less. SPD-Smart architectural products can block more light than other architectural smart window product – over 99.5%. SPD-Smart architectural products also offer more control than any other smart window. With a simple switch or automatically using sensors or timing devices, you can enjoy an infinite number of shading levels – instantly. And they block 99% of harmful UV light at all times, which helps protect interior furnishings and artwork.These features combine to offer superior control over incoming light, glare and heat.

What are some of the benefits of SPD-Smart architectural products?

Variable tint SPD-Smart architectural products enable you to:

  • Eliminate blinds and shades
  • Preserve daytime and nighttime views
  • Enjoy shading on-demand
  • Minimize glare
  • Reduce heating and cooling requirements
  • Maximize daylighting
  • Protect interior furnishings and artwork from fading
  • Operate your windows using a home or building automation system, or even with an iPhone or iPad

What do SPD-Smart architectural products do?

They transform homes and buildings into more comfortable, productive and energy efficient places to live and work. They do this by giving users the power to control the amount of light, glare and heat passing through windows and other glazings products found in homes and buildings.

What types of SPD-Smart architectural products are offered today?

SPD-Smart architectural products include windows, skylights, doors and partitions.
