LoE 270 Glass

LoE 270 allows us to offer windows that provide long-lasting performance throughout the year. LoE 270 is engineered to provide excellent year-round comfort and energy savings; in the summer, it effectively blocks the sun’s heat and damaging UV rays, reducing cooling loads. And in the winter, it reflects heat back into the building, minimizing heating costs. One of the key benefits is its ability to let in ample natural light without the drawbacks of heavily tinted glass, ensuring a bright and inviting interior. Furthermore, its advanced UV protection helps prevent fading of furniture and carpets, making it a smart investment for homeowners concerned about both energy efficiency and interior preservation.

LoE 366 Glass

With LoE 366, you’re getting a high-performance glazing solution that really delivers year-round. Its triple-layer coating is engineered to reject a significant amount of solar heat, which translates to reduced cooling costs in the summer, while also reflecting interior heat back into the building during winter, cutting down on heating expenses. Importantly, it achieves this without sacrificing natural light transmission. Unlike traditional tinted glass, LoE 366 maintains excellent visible light transmittance, providing a clear view and reducing the need for artificial lighting. Plus, its superior UV protection minimizes fading of interior furnishings, making it a durable and cost-effective choice for homeowners.

LoE i89 Glass

LoE i89 is designed to enhance winter comfort and energy savings by reflecting heat back into the room, effectively reducing heat loss. When combined with other LoĒ coatings in a double-pane unit, it achieves U-factors that rival triple-pane windows, meeting stringent energy efficiency standards without the need to redesign window systems. One of its key advantages is its ease of maintenance, with a scratch-resistant surface that simplifies cleaning. Importantly, LoE i89 is engineered to minimize condensation risk, ensuring clear views and lasting performance, making it an excellent choice for homeowners seeking both energy efficiency and durability in colder climates.
