The revolutionary new technology called electrochromic glass, in VELUX electronically tintable skylights, allows full control of the amount of light and heat that enters a room.
As an electric current passes through the glass, it darkens. Reversing the current causes the glass to lighten again. Best of all, it takes less electricity to operate a house full of SageGlass® products than to operate a single 40-watt light bulb.

- Light control at the touch of a button without losing a view to the sky...even in the darkened state.
- Energy savings and elimination of uncomfortable heat gain, even on the brightest and hottest days.
- Maximum protection from fading of furniture or artwork.
- An Automatic Timer Mode can be set to darken the glass at a specified time each day. Instructions for how to activate the mode are included with the product.
This chart compares the visible light and solar heat gain performance of SageGlass glazing in its clear and dark states with that of today's best glazings.
VELUX offers a 10 year warranty on the skylight and the seal of SageGlass IGU's and a 5 year warranty on all electronic functions of the skylight and SageGlass IGU's. For more information on this warranty and electronically tintable skylights from VELUX, please call 1-800-888-3589.
In early 2006, this revolutionary technology is available for the VSE skylight in sizes 101, 104, 106 and 306. Size 606 will be available by Fall 2006. The FS skylight will feature SageGlass in sizes 106 and 306 in early 2006 and in size 606 by Fall 2006. SageGlass is also available for the VCE skylight and the FCM skylight in sizes 2222 and 2246 in early 2006. Most of these skylights are stocked in our Greenwood, SC distribution center. Please call to verify lead times. SageGlass and the SageGlass control system (ZZZ 186) are available for select sizes of fixed (non-venting) skylights. Each fixed model comes with approximately 50 feet of wire to run to the control switch. A single control system can operate up to four SageGlass skylights simultaniously. Please see the SAGEGLASS Pamphlet for details. The amount of time it takes for electrochromic glazing to switch from one state to another depends upon several factors such as glazing size and temperature. Generally, the smaller the glazing and the warmer the temperature of the glass, the faster the transition time will be. Average transition times are 5-10 minutes.
When electrochromic glazing is in its darkest state, very small apparent voids or pin holes in the coating may be visible when looking through the glass. These sporadic pin holes are not a defect and do not affect the overall performance of the glazing. They are a normal aspect of any coated glass, but become more visible because of the large contrast between the bright sun against the dark tinted glazing.
In its default setting, the control system will automatically clear the glass after eight hours of being continuously in the darkened state and the skylight will remain clear until commanded to tint again by activation of the control. This function can be customized by switching the unit to Automatic Timer Mode. In Automatic Timer Mode the controller automatically tints the panes at the same time every day for an 8 hour period, eliminating the need to manually activate tinting every day. The Timer Mode must be activated at the time of day that tinting is desired to occur. For example, if you want tinting to start every day at 9:00am, the Timer Mode must be initially activated at 9:00am on the first day. Instructions for how to activate the mode are included with the product.
The VSE and FS 606 skylights with SageGlass® Product incorporate a thin, center line conductor. This thin line is visible in both the clear and tinted states and is designed to minimize transition time and maximize overall performance of the glass.
