Why can't I use film for heat and uv control?

Arrange a cover for them for when you aren't using the boat.

Why is tempered safety glass not used on boats? Seems like it would solve a lot of problems. I mean most openings are not that big to be unsafe are they?

Dow Corning DC795 is the best sealant for window bedding.

of course there might be other (more expensive) stuff designed for the outside

incidentally, as a cheaper alternative to the sunbrella hatch covers, in our sleeping cabins we use silver duct tape. reflective so keeps the heat out, and darkens the room nicely.

to further darken the cabin during summer, we're trialing some nicely patterned contact (the stuff used to line shelves or cover books) on the inside of the hatch. so far works / lasts well...

cheers,

Hi, so your hatches are acrylic? and they don't craze? how many years craze free?

use tempered glass. 9 mm, any tint you want, even curved , will not break, and cheaper then plastic. just research for it. mine have been on my boat for 20 years.

sorry : i don't know what the hatches are made of...whatever mr lewmar uses. they were already badly crazed (too many years in tropical sun) so the duct tape we put on can't make things any worse

with the deck hatches in the bedrooms we are trying to block out the sunlight as completely as possible. i've thought about painting them but the tape is easier.

the roof hatches in the saloon (also lewmar, also badly crazed) have UF film on the inside and it's very effective to keep heat out & still allow light in but won't do anything to protect the hatch material (whatever it is). as said, it's already badly crazed so cannot get any worse. ther film does mean the crazing can't be seen tho !

all our very extensive side windows are glass and this has the UV film on the inside as well

if using duct tape on the outside of a new hatch, i suspect that it would give complete protection to whatever the hatch material is. you are basically applying a sacrificial surface...

cheers,

Are there any of you with a successful experience of replacing the two VERY long single windows of the Maxi yachts ? See photos.
They are screwed on, and sealed with butyl band. This is the design by the maker. But always leaking...

I have a large roof over my patio made of 1x1 meter tempered 12mm glasses on a steel frame, the glasses mounted with just Dow silicone.
Works perfect.

I'm considering to make a change from the single smokey color PC plate to 4 small 8mm tempered glass windows, bonded by Dow silicone. No screws.
By doing so, I can even put 3M film on the inside.

Where to get it is another question.

Now we are talking... A ceramic coated sun blocking film. Where to get it at smaller dimensions?

Hey thanks chotu. But there is still the concern about adhesive outgassing impact on plastic surfaces.

This is what I was talking about Waaaaaay back in the beginning of the thread. Old technology. Remember I said that?

These new films are the new technology I have been talking about all along that supposedly has solved dealing with the plastic glazing choices like polycarbonate or acrylic off gassing in heat and thermal expansion.

THIS is the current state of affairs. Not what people posted in the beginning of the thread.

Any links to online suppliers / brands?

Yes, thanks for jogging my memory. Now that my original question is answered, has anyone applied a metalized solar control film to the outside of their Windows and where can I buy what you applied?

Looks intriguing but difficult to buy. How about this https://www.windowtint.com/products/...w-tinting-film
