Advice regarding exterior application

[uncle bob]

Have been asked to look at some large windows on a car showroom. Approx sizes are 4 ft x 10 ft all double glazed laminated glass.

Have spoken to a couple of suppliers, they all recommend external application but offer differenet advice regarding the best product.

The main concern offered by 2 are that the absorbtion % should be below 40% even on external applications on laminated glass and it should be edge seeled with dow corning.

Another is advisind a product with an abs % of 49% !

Any advice from some of the experienced guys, please.

The lower the better.

But if the company is willing to warranty it with whatever they recommend......

you should see how much they warranty it for aswell as far as how much per pane. Most is 500.00 per pane and those panes will cost more then that if one has to be replaced. As far as an exterior application like dan said the less the better and yes you should seal the edges with dow corning 795 it will increase the life span of the film.

Thanks for the replies guys. Any supplier I speak to insists I inform the client of the risk "No matter what film is fitted to the laminated glass due to the nature of the product"

I am then informed that the panes in question are 8.8mm laminated and that any film can be fitted internally.

Any thoughts ?

being a showroom, my guess is that they're tempered too....which means that yes, pretty much any film can be used. I wouldn't do an exterior application. definitely interior.

I don't think exterior film is a problem, I'd install it, but if they want an interior film, I'd definitely go with a low absorption film. A dual reflective, or silver or bronze film.

I'd stay away from a neutral film on those windows even if they wanted a 50% film, and I'd DEFINITELY stay away from some of the new "ceramic" films, since they seem to have pretty high absorption too.

I agree. A car showroom would not look good with exterior film.

They could be Lami on both sides depending on the building code. I'd find out what that inside pane is before you do an interior installation.

As I said, regulations state laminated glass over 5 square mtrs must be 8.8mm and the sungard dealer ensures me I can install any interior film on that glass.

Will check wiith merlin lazer gauge to confirm glass make up.

Dealer suggests Nova 70 or 50%, good solar reduction without being too dark or reflective in appearance.

The Sun Guard rep can say whatever he wants but at the end of the day will Sun Guard warranty the window for glass breakage?

The Merlin will tell you what it is.

40sq ft piece of glass I'd go with the 70% and make sure SG has your back.

If they have Heat strengthened or tempered laminated glass it will have alot more absorption tolerance. V-kool offers a couple of varieties if ya con tolerate the expense. Call and talk to Tom at 800SUN2Hot if you are interested....
