When it comes to window solutions, KP is changing the game! Introducing the new Vertex3® SYSTEM, a standard feature now included on all KP window product lines. Vertex3® is derived using three state-of-the-art technologies: Ēvolv Glass Technology, ECTech naturally clean glass, and KP’s Air Sealing Technology. The result, a window that performs higher, insulates more efficiently, and is lower maintenance. Being the only window in the industry to offer three technologies, Vertex3® is positioned to become the benchmark for residential windows.

Ēvolv Glass Technology is a coating placed on the 4th glass surface (interior of the house) that redirects escaping heat back into the home. Not only does ēvolv greatly increase a window’s U-Value, but it offers better light transmittance and less reflectance. Using ēvolv will allow a double pane window to match nearly triple pane performance.
- Triple pane performance with double pane glass
- Outperforms the industry average by 29% in energy efficiency
- Better light transmittance
- All windows meet the Energy Star standards
- Less wear and tear than heavy triple pane sashes
- Less size limitations

- Titanium dioxide coating
- Reacts chemically with the sun’s UV rays, causing organic materials that are on the glass to decompose.
- Extra smooth glass surface
- Causes water to “sheet off” the glass and evaporate quickly, greatly reducing water spotting.
ECTech never compromises. No matter the weather, in particular cloudy days, ECTech performs at a high, energy-efficient level. The color of the glass is never altered, while the glass always remains durable and long lasting.
To test longevity, ECTech has passed the QUV Chamber Test – a simulation replicating real-life exposure over a 25-year span. The test demonstrates that that with ECTech, accelerated UV and condensation cause the glass to show consistent sheeting and photoactivity throughout the timeline.
