Vitro Architectural Glass has launched EcoArmor Protective Topcoat, a film-free alternative that stays on Solarban low-e glass through tempering. Early trials show 10–20% faster tempering cycles and dramatically less waste—reshaping how fabricators handle coated glass.
A Quiet Revolution in Coated Glass Handling
For decades, fabricators receiving high-performance low-e glass have dealt with the same chore: peeling the temporary plastic film off every lite before tempering, hauling the waste to a dumpster, and absorbing the labor and disposal cost as a line item on every IGU. Vitro Architectural Glass is now trying to eliminate that step entirely.
Vitro Architectural Glass announced the launch of EcoArmor Protective Topcoat, an advanced full surface protective coating on select Solarban solar control low-e glasses that safeguards throughout transit, storage and fabrication. Unlike traditional temporary protective films, EcoArmor Protective Topcoat delivers full surface protection without added waste, time consuming removal steps or disposal costs.
The critical engineering breakthrough: EcoArmor is engineered to remain on the glass through tempering, streamlining fabrication workflows and delivering measurable performance advantages in demanding production environments.
The Performance Numbers Fabricators Care About
This isn't just a sustainability play. The data Vitro is publishing from production trials points to real throughput and quality gains:
- Currently available on Solarban 90 glass, EcoArmor has helped fabricators reduce tempering cycle times by 10–20%, minimize roll wave distortion and decrease edge kink by up to 33% on glass with pre-temper edge deletion.
- In trials with the Vitro Certified Network of fabricators, they consistently observed more uniform glass exiting the furnace compared to alternative products, along with improved production flow and higher overall quality.
For glaziers and curtain wall fabricators chasing tighter tolerances on roller wave (a perennial complaint on commercial vision glass), the edge kink and distortion improvements are arguably more interesting than the labor savings.
Workflow Compatibility
One reason temporary protective films persist despite their downsides is that any replacement has to survive cutting, seaming, washing, and the IG line without disturbing the underlying coating. Vitro says EcoArmor clears that bar:
- Fully compatible with standard fabrication practices, including cutting, seaming and washing operations, fabricators can process glass with EcoArmor Protective Topcoat using the same equipment already in place.
- Vitro recommends a minimum 1" trim be taken in order to properly break out the glass with EcoArmor. Solarban Temperable coated low-E glass must be edge deleted, and EcoArmor coated low-E glass can be edge deleted using conventional deletion equipment.
- A more aggressive abrasion wheel may be required when edge deleting through the EcoArmor protective coating.
In other words, fabricators won't need new capital equipment, but quality control teams should expect to retune deletion wheels and inspection protocols for the matte post-wash appearance the topcoat leaves behind.
Why This Matters Up the Spec Chain
For architects and building product manufacturers, the EcoArmor launch carries three implications worth tracking:
1. Embodied carbon and EPDs. As more projects require Environmental Product Declarations and chase whole-life carbon targets, eliminating single-use plastic film from the glass supply chain is a tangible win. Vitro framed EcoArmor as a more sustainable, future-ready alternative to traditional protective films, which are time consuming, messy and send unnecessary material to landfills while adding complexity and inefficiencies to glass fabrication.
2. Coating availability is still limited. EcoArmor is rolling out gradually. It is available exclusively through the Vitro Certified Network, with Vitro expecting EcoArmor to be available on additional Solarban low-e coatings later this year. Spec writers locking down glass selections for 2026–2027 commercial projects should ask their reps which Solarban products will be EcoArmor-compatible by their fabrication date.
3. Quality control protocols need to be updated. The EcoArmor coating is not water soluble and will not dissolve in the washer. The coating will still have a hazy or matte appearance after washing and there may be an appearance of minor surface damage (scratches, pitting, etc.) which is not a concern unless the damage extends down through the Solarban coated surface. Glaziers and project superintendents performing field receiving inspection should brief crews so EcoArmor's matte pre-furnace appearance isn't mistakenly rejected as defective glass.
The Bigger Picture
EcoArmor is a small product announcement with outsized implications for daily practice in the architectural glass supply chain. Tempering bottlenecks have been a chronic constraint on commercial glazing throughput, and roller wave distortion remains one of the most common quality complaints on large-format vision glass. A topcoat that simultaneously reduces both—while also eliminating a stream of plastic waste from every fabrication plant in the Vitro network—is the kind of incremental innovation that doesn't make architectural magazine covers but does change how spec sheets, shop drawings, and unit pricing get built.
Expect competitors—Guardian, NSG/Pilkington, Saint-Gobain, AGC—to respond with their own film-free protection strategies as the value proposition gets validated by Vitro Certified fabricators over the next 12 months.
