Just to throw some further fuel to the fire, if choosing/comparing between a ceramic and similarly performing silver film, which is

1. More aesthetically appealing?
2. Susceptible to corrosion, affecting warranty and longevity?
3. Signal friendly?

Just some considerations that may or may not influence different customers in different applications.

GTS, I understand the frustration of restricted access and I don't think Eco will be as strictly hard to get a hold of. My understanding though is that SG certainly have "preferred" customers, which is fair enough, probably 80% of their turnover comes from 10% of their customers. That's to say they look to reward loyalty and commitment.

The Ecolux will be right up there in price (it has gold in it) so you won't be competing with Enerlogic on that aspect.

But from what I have seen and heard, there is no special application quirks like the Ener.

Only comes in 70% (68%) but actually out performs Ener by a bees dick.

Same winter U factor, 2% better SHGC (3% better SC) but achieves this by being 3% more externally reflective (11% but who cares on a 70?).

 

 

Its a fast fix to keep up with the Joneses on paper but it has limitations, as does the Enerlogic.  I hear good things and bad things about both.  Im not sure it would be worth your time bc I dont know the climate down under, but where I am, its no good since we dont really have long enough winters to see a ROI, mainly bc of the price.

Yeah, only a few regions down here will truly benefit from such a beast (Canberra, Melbourne, Tasmania) and coupled with price, it won't be a typical retail product. What we do have down here is a slowly growing push for energy efficiency though which is starting to push some sales of LowE films. An annoying aspect of that is that even though there are established heating and cooling zones, energy assessors continue to place too much importance on U value. In hot  climates, the U value is really of low level importance but the "experts" see the energy efficiency "benefits" of retaining heat.

As a result, specifiers try to get that low U value in places where you really only want to keep heat OUT. Even if you experience some cold nights, the % spent on heating compared to cooling are small. Often this means a compromise on heat rejection and the film that assessors like on paper is no where near as efficient as they could have.

Even in Brisbane we get calls for LowE films to try to achieve a good U value and end up putting film on to look good on paper rather than do the best job. It also means you are competing with Enerlogic in climates where it is near pointless.

I don't know how it works over there, but down here you have to be "trained" and certified to use Enerlogic (otherwise hard to get and no warranty).

 

You almost sound like you know what you are talking about AT.

I agree thoroughly though, in the QLD sub tropical climate, there is very little need for a LowE product like Enerlogic, as good as it may be.

I have only come across LowE glass twice now up here, and most Glaziers here are only vaguely aware of it, but never use it.

 

I raised an eyebrow though at a recent trade event where an experienced tinter from the Far North Queensland was selling heaps of LowE as "It insulates the glass and helps prevent the  cool air conditioned air from escaping ????"

Not sure if it works that way exactly. Well not as well as he thinks it does, anyway.

 

Cheers.

Low E won't directly keep "cool in" . It reflects radiant heat (infra red).

Cool air doesn't "escape" as such, but is replaced with heat coming in. So in terms of protecting the cool air inside, a simple silver20 will do the job best.
