Low energy efficiency in replacement glass units
I had 12 glass units replaced in 2 windows last year. They develop a cloudy film on the surface and have to be cleaned often. A local glazing firm checked them and informed me that there is no ‘E’ coating and an energy efficient product has been replaced with an inferior one. Has the glass replacement company broken any regulations and does he have a case to answer for downgrading my home’s energy efficiency? He appears to be a member of several trade organisations. Many thanks for your help.

There is no condensation, just a gradual build-up of something that leaves a foggy film on the surface which can be removed by cleaning. The local tradesman used a gauge which beeped on all other windows, but not on the new ones. He said that indicated there was no ‘E’ coating and the new glass is less energy efficient. Is it reasonable to expect a tradesman to replace glass of a similar quality or, at least, explain that the replacement is less efficient? I need to know if the installer BROKE ANY REGULATIONS or if he has A CASE TO ANSWER FOR DOWNGRADING THE ENERGY EFFICIENCY of my home. Many thanks.

Sounds to me like the the coated glass has been put on the outside

The installer should of been clear on his quote & invoice for what rating of glass he was installing. He should of also asked what rating of glass you currently have or would like perhaps. So long as the glass fitted is ‘C’ rated then this is sufficient for building regulations and as far as I’m aware they haven’t technically done wrong except for not being clear. The glass could be fitted the wrong way round, but I always thought that e coating was applied to the two middle sides of glass not the outer two.

玻璃可能是glazed with the coating to the outside, which would when standing back give the appearance that the glass is different from rest of glass, the simple test would be to deglaze the unit and turn the unit around, if it still appears that it looks cloudy then there could be a fault on the coating, however if there was no coating at all on the glass the glass would just simply appear to be clear which ever way it was glazed !

I have to agree with Jamie Davis on this one. It does sound like the glass has been fitted the wrong way around. This will mean that the energy efficient surface is on the wrong side and cause it to condense up.
