Low E II coated double glazed windows with argon gas will substantially reduce heat loss in cold climates, and therefore reduce your heating costs. Low E II coating reflects heat back to its source so winter indoor heat is retained and summer heat is reflected outdoors. UV rays are screened to reduce fading and damage to upholstery and carpets.
Argon gas, which has thermal conductivity 30% lower than that of air, also contributes to the efficiency of the window or door. Low E II and argon gas further enhance the performance of your windows and doors, resulting in long-term savings for you.
