Hi Everyone,

I have recently found out this thing called Thermal Glass Coating thing, or nano coating something like that, it is supposed to reduce UV, improve insulation, reduce heat lose compare to normal glass, has anyone used this thing around here? how well does it actually work....

you can google it or search in youtube and there are some video about it...

thanks in advance

I wonder if this is what he means

And no I haven't used it.

What a load of crap on that kristal bond page. The grammar is terrible as well

"In the winter, the heat you generate inside your home, is absorbed into the glass, forming a heat curtain, or barrier. Neither Double Glazing or window film can does this, which is why the coating is so effective. "

There was a case several years ago where the advertising standards authority gave a similar company a spanking for unsubstantiated claims about the performance of it's product.

"A claim that a window film would "keep in 90% of your home's heat" was likely to mislead consumers the Advertising Standards Authority has found."

I can't really afford doing double glazing, because i have got aluminium frames in my house, i want to improve insulation of the windows, i also suffer from the intense sun in summer as rooms get too hot and furniture gets de-coloured by the sun, if this solution can really do reduce UV, make room cooler in summer, improve heat loss in winter, reduce condensation at the same time, it just sounds too good to be true.

check these video out, one of them is in japannse, anyone understand japanese?

yes, that is the nz site i found that does it. there are a number of companies in Japan, USA that do similar things, not sure if they all use the same product, or similar.

yeah, i agree, that sentence doesn't really make sense. I still don't understand what they are trying to say there.

Have you looked into retro-fitted double glazing? They can use the existing aluminium frames and they make it look pretty painless. I have no idea what it costs, but you could look at just doing it only for the windows you are having trouble with to keep the cost down. I'd suggest a tinted window pane at the same time which may help with the heat and furniture fade. Or for the really cheap option, some venetian or roman blinds could help.

The floor to ceiling window in my dining area has tinted double glazing as well as roman blinds. The room faces west, so in summer I draw the blinds and angle them at 45 degrees when I get home from work to take the sting out of the sun.

Sure it isn't painless on the wallet though. There are different companies that do this using different methods, some better than others. But the best way is to install proper IGU's into the frame. Retrofitted IGUs will have to be a lot thinner, with thinner glass and air gap, so aren't likely to be as effective as new windows with IGUs. If doing significant renovations, you will usually see the entire window replaced, and that also gives the option to install thermally broken frames. Last time I got a quote for a new build last year, thermally broken frames are about 30% more to have thermally broken frames at the moment, which doesn't make too much sense, but hopefully that price will come down, and they will become standard. Unfortunately not too much competition in the materials market in NZ, so for many materials we do pay a lot more than they do overseas.

To be honest, even with double glazing, you will still get a lot of heat loss through the windows. A better use of money for more gain can be super insulation on the ceiling which has the most heat loss, and possibly walls.

The problem with treatments on single glazing is that, even if you inhibit infra-red (heat from inside), conduction takes over to decrease the temperature gradient between inside and outside.

Glass is already a reasonable barrier to ir (that's why your car heats up so effectively when it's parked in the sun).

No it isn't if glass was a reasonable barrier to IR then your car wouldn't heat up when parked it the sun most if not all car windows have some for of UV protection but none have any form of IR if clear glass some factory/after market tinted windows do have limited IR protection simply because of the tint

The energy that heats up the inside is from visible and higher frequency IR radiated in. IR from the inside surfaces of the car does not radiate out so easily.

And that's because glass is a very poor heat conductor

No, conduction and radiation are different things. I did say in my first post that conduction becomes lthe primary driver of heat loss when radiation is reduced. Double glazing reduces conduction loss in combination with radiation loss.

Looks like a number of outfits are providing this service. I had a look at a few websites. The claims about UV reduction and IR reduction should be easy to verify with cheap equipment.

Then it's down to two things: The quality and durability of the formulation, and the skill and technical ability of the applicator.

What surprises me, I can find no well known names supplying this stuff. For instance, if it was any good, and durable, I'd expect 3M or similar to have a product. The fact that they don't, makes me suspicious as to the durability and reliability of the product.
