Thermal insulation

When room temperature falls below 11 degrees there is the risk of thermal discomfort inside the room. It has a low U-Value of just 1.35 compared to 1.6 of regular low-E double glazed.


Easy-clean coating

LoE³-366® comes standard with Neat, a titanium dioxide layer which harnesses the sun’s rays to loosen dirt so the rain can wash it away with minimal streaks.
