Why is my Low-E double glazing hazy?

It is normal that Insulating glass with Low-E coatings exhibits a blue-gray “haze” under certain viewing conditions. Particularly when the Low-E glass is partially in direct sunlight and partially in shade, a haze will be visible in the sunlit portion of the glass when viewed from the interior.
Low-E coatings have become so popular because of performance benefits –heating and cooling cost savings, greater occupant comfort, reduced fading of interior fabrics and wood floors.
As with all glass, there is the potential for the double glazing to display a ‘blue haze’ at certain times throughout the year, either when the sun is at a particular angle or when viewed under some lighting conditions. Haze can appear blue in colour and looks similar to a transparent film or a cloudy effect on the glass. It can give the impression that the glass is faulty but it isn’t. It’s a natural occurrence due to the thermal coating and nothing that Safe Style can rectify. It will not cause any permanent damage; it is the product we sell/supply.
