Cardinal LoE2 glass is designed to provide you with year-round savings and comfort by optimizing both the sun's heat and your home's heating and cooling systems. In the summer, LoE2 keeps your home cool and comfortable by rejecting the sun's heat and damaging rays. In the winter; Cardinal LoE2 glass helps your home stay warm and cozy by reflecting heat back into the room.   State-of-the-Art Process: In Cardinals state-of-the-art sputter coating process, the glass is first coated with microscopically thin, optically transparent layers of silver sandwiched between layers of antireflective metal oxide coatings. A protective coating layer is then applied to ensure durability and scratch resistance for long life. These invisible coatings provide the best clarity and performance of all low-and mid-emissivity glass products.
