HOW DIAMON-FUSION® WORKS?
Every day, residential windows and high-rise buildings are exposed to hard water and environmental pollutants that leave it at risk of becoming permanently damaged. Diamon-Fusion® is a hydrophobic coating for house windows and other commercial building glass that fills in the microscopic peaks and valleys of the glass surface, creating an ultra-thin, transparent barrier that seals the glass for years to come.
Tested and approved by: DOWSIL™ Sealants, Sika® Sealants, Intertek, Fenzi, Smith-Emery, and Chemir. CSI Reference Section 09 01 10.92 – Protective Surface Treatments.

“I just can’t say enough good things about Diamon-Fusion®. Other than a few touch ups, we haven’t had any exterior window cleaning since the coating was applied to our glass nearly one year ago.”
“The Academy’s experience with DFI has been very positive. The end product is everything I was told it would be, resulting in lower labor and material costs. My custodians only use a microfiber cloth and no chemicals.”
“I am very impressed with DFI and am looking to incorporate Diamon-Fusion® across the campus. I have cut my window cleaning by 50% and saved $12,000 – $14,000 per year since it was applied.”
“The cost we acquired in restoring and coating the glass exterior pales in comparison to what we would have spent had we replaced the glass. I would recommend this treatment on any building.”

FREQUENTLY ASKED QUESTIONS
How long does Diamon-Fusion® last on windows?
Diamon-Fusion® is backed with a lifetime warranty for residential windows and a 15-year warranty on commercial building windows, as long as the basic manufacturer care recommendations are followed. The coating is guaranteed to remain more water repellent than an untreated surface for the lifetime of the glass.
How much does it cost to get Diamon-Fusion® applied to my windows?
Prices are determined by DFI resellers according to their own business strategies and market segments. Although prices do vary depending on geographical areas and markets, Diamon-Fusion® has proven to provide the best combination of price and performance of any protective coating available on the market today.
Can Diamon-Fusion® be applied to Low-E glass?
Yes, it can! Also, because Diamon-Fusion® keeps glass cleaner for longer and optimizes the energy output of high-performance windows, as a result, it will also enhance the performance of Low-E glass.
Why should I get window glass treated with DFI’s FuseCube™ coating machine?
DFI’s FuseCube™ is a fully-automated glass protectant coating machine that applies Diamon-Fusion® through a proprietary chemical vapor (CVD) process. Getting your windows treated through the FuseCube™ ensures Diamon-Fusion® is fused onto both sides of the glass in a uniform application. To find a glass processor near you who can treat your windows using the glass protectant coating machine, please contact DFI.
Can Diamon-Fusion® be applied to existing window glass?
Yes! DFI has a network of certified onsite applicators who can apply Diamon-Fusion® to your high-rise building windows or the windows at your home. learn more about our onsite application services, or contact us today to receive a quote on having Diamon-Fusion® applied to your glass.
Will Diamon-Fusion® break down when exposed to sunlight?
Never! Diamon-Fusion® is UV-resistant; so, when applied to windows, the coating will never break down when exposed to sunlight.
Does Diamon-Fusion® help reduce water spots on windows?
Yes! Diamon-Fusion® creates a protective barrier that prevents water spots from forming on glass surfaces. By repelling water and other contaminants, the coating helps maintain cleaner windows for longer periods. Unlike untreated glass, which allows minerals and debris to settle and leave behind stubborn stains, Diamon-Fusion® reduces the need for frequent cleaning. For best results, a microfiber towel can be used to gently wipe down the glass, ensuring a streak-free finish while preserving the coating’s effectiveness.
Can Diamon-Fusion® help protect against harmful UV rays and reduce glare?
Diamon-Fusion® coatings are UV-resistant and will not degrade when exposed to sunlight. While the coating itself does not block additional UV rays, it doesn’t need to—automotive windshields are typically made of laminated glass, which already blocks 100% of the sun’s UV rays. Diamon-Fusion® protects the windshield surface, which in turn protects passengers from UV exposure.
Concerning glare, absolutely! Diamon-Fusion® has been shown to significantly reduce glare, particularly nighttime glare.
Diamon-Fusion® coatings reflect light, which helps reduce glare and improve visibility on windows and windshields. While the coating itself does not replace UV-blocking glass, it enhances the performance of existing UV-resistant windows by keeping the glass clean and clear for optimal light transmission. This protection is especially beneficial for homes, offices, and vehicles, as it minimizes sun-related glare and enhances comfort indoors. Whether applied to windshields, windows, or glass facades, Diamon-Fusion® ensures long-term clarity while helping to maintain a pristine look.
