Q. How many types of Low “E” are produced
A. All the major “Float” manufactures produce thair own Low “E” glass, each has a brand name,
Pilkington : “K” Glass, Guardian “D” Glass, and Glaverbel “G” Glass. All the coating perform in the same way, by reflecting radiated heat back into the room, and all have a similar “u” value.
All low “E” coated glass has a slight tint,, Guardians “D” glass has what we prefere to call a “daylight” tint, that is very pleasing to the eye, as it is slightley blue, Pilkingtons “K” glass has a slightley brown tint, which is noticable when viewing white georgian bars and net curtains through the glass.
Q. Will the coating effect my view through the sealed unit.
A.In some instances the coating of low “ E “ glass can give a translucent haze effect when viewed in direct sunlight, this is a positive proof of the coating being present, a not a defect in the glass. This translucent haze effect is not a defect in the sealed unit, and therefor the sealed unit would not need replacing,.Haze can occur on most coated glass. However, the effect will be more noticeable on some types of coated glass than on others. Haze gives the appearance of a fine, uniform, layer of dust deposited on the surface of the glass. The effect is more noticeable when the glass is viewed at an angle or under strong light. In situations where the glass is in partial shadow, the shaded area will be free of the effect, giving a clean appearance in the shadow and a dusty appearance in the lit area. This contrast can be very noticeable. Hard coated low-E glass can manifest this effect. The reason for this is that coating is not as smooth as the glass surface. This 'roughness' of the coating is not apparent to the human eye. This 'roughness' scatters a small proportion of the light striking the surf ace.
