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 1.34 compared to 1.6 of regular low-E double glazed.


Easy-clean coating

LoE-452® 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.

A clear quad silver low-E with a subtle grey tinge and the next level of performance makes LoE-452 the superior option for solar control and light balance. In fact it boasts an LSG (Light to Solar Gain) of 2.33, matched only by LoĒ³-366®, only LoE-452 has a lower SHGC which gives it added performance. Due to its outstanding solar control, we recommend it for both commercial and residential applications in predominently warm climates or western facing elevations in mixed climates.

Commercial applications:

  • Education facilities
  • Accommodation
  • Public spaces
  • Hospitality
