1. How do I spec Suntuitive Glass?
Please contact us for specific bid specification information. Suntuitive Glass consists of an interlayer that is laminated between two pieces of heat strengthened or tempered glass and placed into an insulated glass unit (IGU) with a low emissivity coating. A warm edge spacer is also recommended. Suntuitive Glass can be used in standard laminate IGUs, double laminate IGUs, triple pane IGUs with an overall thickness of 3/4” or greater. In some applications, monolithic Suntuitive Glass can be appropriate.
2. How can I buy the product?
Suntuitive Glass is available for most window manufacturer frames and framing options. Please give us a call at 616.662.7216 or email us to discuss your project and we will connect you with a local representative or an authorized Suntuitive Glass distributor.
3. What is the difference between Suntuitive Glass and other dynamic glass technologies?
Suntuitive Glass is a thermochromic technology which uses heat to continuously transition throughout the day – providing infinite transmission stages. This is different from electrochromic that uses electrical voltage to transition between set stages or thermotropic which is triggered by a specific temperature and uses heat to change between two defined stages.
4. How durable are Suntuitive windows?
Pleotint is committed to long-term durability and in addition to continuous and vigorous internal testing, Suntuitive interlayer has:
- Completed 8,000 hours of accelerated aging testing under ASTM E2141-06
- Completed 2,500 hours of accelerated aging testing at the National Renewable Energy Laboratory (NREL) and QLab Corporation
- Completed independent testing at the Lawrence Berkeley National Laboratory (LBNL) and Architectural Testing, Inc (ATI)
- Passed Impact Test: CPSC 16 CFR 1201
- Passed research Hurricane D-missile impact and cycling tests
- Passed Forced Entry Test: UL972
- Completed Acoustic Test: ASTM E90-09
5. Can Suntuitive Glass be modeled?
Absolutely. Data for Suntuitive interlayer is available in the International Glazing Database (IGDB) and National Fenestration Rating Council (NFRC) Ratings are available with Suntuitive interlayer.
6. Can Suntuitive Glass help obtain LEED® credits?
Suntuitive Glass can contribute toward LEED® certification in the following categories:
- Integrative Process
- Energy and Atmosphere: Optimize Energy Performance, Demand Response
- Indoor Environmental Quality: Thermal Comfort, Daylight, Quality Views, Acoustic Performance
- Pilot Credits
AVAILABILITY / USAGE
7. Can Suntuitive technology be used as a post-application film?
No, Suntuitive Glass consists of an interlayer that comes laminated in between two panes of glass and cannot be applied as a film onto existing windows. Suntuitive self-tinting glass can be installed into new construction or retrofit applications.
8. How is Suntuitive Glass installed?
Suntuitive Glass installs the same as any other typical glass unit (or IGU) and can be glazed at a window manufacturing site or at a project site.
9. In what applications can Suntuitive Glass be used?
Suntuitive Glass can be used in retrofit, replacement and new construction in both commercial and residential applications. The glass can be vertical, sloped, curved or shaped. In additional, it can be combined with most tints of glass and paired with many different Low-e coatings.
10. What is the lead time for Suntuitive Glass?
Lead time is the same for Suntuitive Glass as with traditional glass and will vary depending on fabrication requirements.
11. Can Suntuitive Glass be used in operable framing systems?
Yes – since there is no wiring involved operable framing systems can utilize Suntuitive Glass.
12. What are the maximum dimensions of a Suntuitive Glass unit?
64” x 144”
13. What is the warranty on Suntuitive Glass?
Pleotint, LLC offers a 10 year industry standard warranty on Suntuitive.
14. How does the product function?
Suntuitive Glass, produced by Pleotint, LLC, consists of an extruded polyvinyl butyral (PVB) interlayer with thermochromic properties. The thermochromic glass lightens and darkens by itself – with absolutely no mechanical or electrical intervention – based on heat from direct sunlight.
15. What does Suntuitive Glass look like from the outside?
While clear, Suntuitive Glass looks just like traditional glass. When tinted, Suntuitive Glass will appear dark gray from the exterior. Looking through tinted Suntuitive Glass is similar to wearing sunglasses, where the glasses appear dark from the outside, but are easy to see through from the inside.
16. How fast does Suntuitive dynamic glass tint?
Suntuitive Glass will fully tint in 20-30 minutes of direct sunlight. Likewise, it will take 20-30 minutes for the glass to return to the clear state.
17. What is the technical performance of a Suntuitive window system?
Glass performance is based on the construction of the glazing package with Suntuitive Glass. A one-inch overall clear Suntuitive Glass construction with a high-performance Low-e coating will have a visible light transmission range of 54% - 8% and a solar heat gain range of 0.36 – 0.16. Additional construction performance information can be found in our technical brochure on our Resources page.
18. What temperature does Suntuitive Glass start to tint and where will Suntuitive be most beneficial?
While continuously variable, the most active range of Suntuitive is when IGU pane temperatures are 77°F (25°C) to 150°F (65°C).
Structures that are subjected to abundant and direct sunlight will especially reap the benefits of Suntuitive Glass. In the United States this includes East, South and West-facing facades that receive direct sunlight during the day.
19. What are the energy savings of Suntuitive Glass?
Based on a study at Lawrence Berkley National Laboratory (LBNL), using Suntuitive® Self-tinting Glass provides an annual energy savings between 20-43%. The greater the window area, the greater the energy savings. (An empirical study of a full-scale polymer thermochromic window and its implications on material science development objectives 4 May 2013)
Suntuitive Glass is available for modeling in the International Glazing Database (IGDB) and National Fenestration Rating Council (NFRC) Ratings are available. Please CONTACT us if you need direct assistance with modeling for an energy savings estimate.
20. Will Suntuitive Glass get too dark during peak-sun hours?
Suntuitive Glass provides more consistent daylighting throughout the day and balances what would normally be a spike in illuminance that traditional glass lets in. During times of peak sun exposure, when Suntuitive Glass will have its lowest visible light transmission, it is still letting in the highest amount of daylight.
21. Will Suntuitive Glass tint on a cold sunny day?
Suntuitive Glass is designed to balance solar heat gain and visible light transmittance for the majority of climates and provide as much daylighting as possible while blocking out solar heat gain at the same time. Since our product is thermally activated, it is affected by exterior temperatures, wind and sun angle. On cooler days, Suntuitive will not tint down as much to allow in passive solar heat.
22. What if my building is surrounded by other buildings, will Suntuitive Glass still tint?
If there is direct sunlight on Suntuitive Glass, the glass will tint.
23. Does Suntuitive Glass meet Title 24 Standards?
Yes. Title 24, also known as the “California Building Standards Code”, is part of the Energy Efficiency Standards for Residential and Commercial Buildings. The new standards place rigorous performance requirements on glass that require the use of advanced technologies. The California Energy Commission lists Dynamic Glazing, particularly Thermochromic Glazing (Suntuitive Glass), as a solution to meet the new rigorous fenestration requirements.
