One recently (9/09) installed West facing window has exactly the same outside condensation problem. It occurs early in the morning and usually disappears mid morning. The other new windows facing South and North do not show any outside condensation.

It needs to be Hydrophilic like Activ or Bio Clean (which incidently do not filter out solar heat gain and so make no difference to the internal low e pane) as opposed to Hyrophobic like Ritec, Allclear, Glassguard CG100 etc which all repel water and cause tiny droplets (misting up) with a Hydrophilic coating the water can not form into mist (tiny droplets) hence its use inside premium face masks and goggles etc.

Nice and techi hey

Perhaps an application of clearshield from Ritec would solve the prolem plus cutting down on the cleaning costs etc

Scott, I would guess though that you could not sell these products as A rated as they would filter out your solar gain . I think that they may not even achieve a C rating so will not comply to the 2010 regs. Is It dificult to upsell a product of lower specification , that may not comply to regs ? Besides if it solves the problem of condensation on the outer pane it is purely conducting more heat from inside and is therefore less efficient.

As it happens on the shaded non sunny windows Activ or Bio Clean will solve the problem, so this needs to be taken into account during the survey/sale another option to upsell…

tell your wife to think herself lucky that when she wakes upon that cold autumn morning that the ice is on the outside,when I wake up we have ice and condensation on the inside Brrrrrrrrrr.Could really do with investing in a new product on the market called Central Heating!!!!! lol . On a serious note we too have had several customers inquiring about the same problem as yourself and after speaking to them and directing them to the relevant websites etc I have found that we have had more of a positive reaction rather than negative. good to see your back on line and looking forward to glasstalk

Hmmm – that’s a tricky one. After all, windows are for looking out of.

We did have a similar occurrence here at the Fabulous Photo Gifts office when a customer, upon receiving their photo jigsaw, rang to complain that they weren’t happy because the pieces were irregular shaped.

That took some explaining.

I think the consensus of opinion seems to be that condensation on the outer pane is there because the windows are performing well as an insulator. If anything this has made me more convinced to sell more energy efficient windows as I can now physically see the proof on my own windows.

It’s a small price to pay having the odd morning with external condensation on the glass. Our company never had any noticeable concern from customers about this ‘feature’ until we started marketing and installing a lot of A Rated windows this year. Customers are right to question why this is happening so the lesson for me is to ensure that they are informed at the point of sale that this may occur. We need to get the message across of just how well the windows will perform.

Many thanks for all the comments.
