Many Multihulls because of the sloping windows inherent in the design, invite the SUN into the main Saloon (exceptions - the Lagoon and the Leopard ) Glare, UV, Heat - result HOT -- fading materials, aircon on, no privacy.

Just installed top of the range window film in friends Cat - keeps out most of the UV - reduces heat - no aircon required ! See out - cannot see in !

GOOD QUESTION

Good adhesion on Lexan windows in my own catamaran. Recently applied to friend's cat, also Lexan - no problems.

Perspex by any other name, including :-
Plexiglas, Vitroflex, Limacryl, R-Cast, Per-Clax, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass, Optix and Lucite and is commonly called acrylic glass, simply acrylic, perspex or plexiglas.

Suggest if you have a small port or hatch with "Perspex" or even better a piece of the same material, ask a supplier for a sample of the film and apply as a test.

In the meantime I have emailed 3m with your specific question - if/when they reply I will post here.

Regards

Richard

Followed the suggestion :- found a piece of 4mm clear Perspex (Acrylic glass) took it to a pro-shop
who apply the 3M film to automotive glass windows.
The technician then took me through the whole process of applying the film - took about 5 minutes.
He advised, that he has applied the film to acrylics many many times without a problem. He added that he had applied all the various types that 3M produces. The shop guarantees the film for 5 years, same for acrylic.

Here are a couple of pictures of the test -

How does this affect night vision?

[MMNETSEA]

Hi Gavin,

The film has a dual characteristic in that the outside is reflective - cutting out UV glare and heat and to an extent, light; while the inside is not reflective in daylight. I know that in some countries the vehicle driver's vision should not be impaired - the area of glass in front of the driver to be kept clear. In my own catamaran during watch at night always checked for lights etc from outside. I suppose one could leave a forward window clear but with a hinge down filmed window behind it, so that in daylight the hinged window would be down.
Tonight, with that piece of filmed perspex, I will check to see how much it cuts out lights and shapes.

How did the 3m window tint hold up on your lexan windows. They keep telling me it will not work because of the outgasing of lexan. This creates bubbles in tint. Did you use the color safe 3m tint? Polygard is a brand made for lexan but it is $45 a linear metre. Big cost for experiment. Did you ever get a response from 3m?

Hello Steve,
Sorry I did not reply earlier - missed your post - but did answer a PM.
I only applied the 3M material to my lexan windows after they had been on the cat for about a year, pleased to report that never had bubbles or other blemishes as a result of some chemical reaction from the Lexan. I am not sure was is meant by "outgasing of lexan" - does this imply that Lexan exudes some type of fume? Could it be that after a period in the sun that lexan cures and no longer releases "gas" ????
Never got a reply to my questions to 3M - they directed me to the distributor in Thailand - who did not speak enough English to understand the questions.

There is a product called PolyGard carried by Sungard in Australia. It is made for all types of plastics. It uses a special glue that is easy to remove. It can be applied to outside or inside. It is very hard to scratch so quite durable.
