gzt: 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.

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 of the product.

 

 

 

it looks like they sell this product for $117 in the US, but i don't know how to ship it to NZ. The NZ company may not want to sell just the product. 

 

If there is a way they can be shipped here, i don't mind buying a gallon try it out. it doesn't look like a rocket science to apply it on the glass. 

 

 

 

if it indeed does what they say it does, it would be a excellent product, i wonder why it did not become popular in NZ.

looks like they can do international shipping

 

1 gallon for NZ$168, plus shipping for NZ$316, enough to covers about 14 square meters.

 

or 5 gallons for NZ$843 plus shipping for NZ$892, enough to cover about 70 squre meters.

 

an average 3 bdrooms house in NZ should have 25 squre meters i guess? 2 gallon should be enough.

If it's too good to be true...

 

One significant point - this is translucent - that means it lets light through, but scatters the light.  So only apply to windows that you don't want to look through

Another way to look at it is, suppose the film is very good with IR and could maintain a temperature of 20 degrees on inside surface of a window and 3 degrees on the outside surface, based on IR properties alone.

Well that temperature difference couldn't be mantained as glass is a good conductor of heat (and a thin film won't help) and heat will conduct to quickly make the temperature diffrence very small.

Glass is already reasonably opaque to IR energy generated from objects at room temperature. Low e glass makes that better of course but you don't get single pane low e glass installed much because any small gains would likely not justify the cost.

yinian:

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.

 

 

It does sound too good to be true. There are add-on window films you can apply that provide some of the benefits of double glazing, but the really good ones cost about 90% of what double glazing would cost.

 

 

If you want a cheap solution, apply standard UV/IR-reflective film for summer and hang some thick thermal drapes for winter. That'll give you better protection than double glazing.

that is what i am trying to find out, want to see if anyone here could provide some feedback on this new zealand company and its product, any similar coating product.

That company still exists. Call them and ask if there were any problems with the product. Who knows they may have a bucket or two still sitting around.

Feel free to spend your money, but there are a few things that rung alarm bells for me:

there is nothing on the site that identifies any individual in the organisation which seems strange
the address seems to be an anonymous office when you look for it on google street view
none of the "business publications" are ones I have heard of, and without much investigation appear to be paid advertising

And then when you enter industrial nanotech scam into google some of the top results appeared to confirm my concerns.

I've learnt not to use this stuff on double glassing. I had a sample piece on my double glazed windows for about 2~3 weeks. Somehow the air gap between the two pieces of glass got super heated and ruptured the seal causing a vacuum which allowed water to ingress into the air gap. The water vapor caused the the inside glass panel to have a constant moist damp patch that never went way until I got the glass replaced. $$$

Have a serious look at PVCu double glazing.  I have had 2 x 100sqm units done for $12k each, or if you like about $25 per week extra on the rental price.  Using argon gas and laminated glass you get double IR filtering, heat retention and a new seal.  

 

PVCu is also thermally insulated of course, making aluminium look like the product it is - outdated.

 

The difference is unbelievable, the tenants love it.
