SUMMARY

The discussion centers on finding a waterproof yet transparent material suitable for roofing a balcony area for drying clothes. Participants recommend using corrugated or multiwall polycarbonate sheets, which are available at major hardware stores like Home Depot and Lowes. While polycarbonate allows UV light to pass through, Lucite (plexiglass) does not, making polycarbonate a better option for disinfecting clothes. Concerns about polycarbonate yellowing and distorting over time were addressed, with some users reporting no significant degradation after several years of use.

PREREQUISITES
  • Understanding of materials science, specifically regarding polycarbonate and acrylic properties.
  • Familiarity with UV light transmission and its effects on disinfection.
  • Knowledge of construction materials and their applications in outdoor settings.
  • Basic principles of weather resistance in building materials.
NEXT STEPS
  • Research the long-term durability of polycarbonate sheets in outdoor applications.
  • Investigate alternatives to polycarbonate, such as tempered glass and their properties.
  • Learn about the installation techniques for corrugated roofing materials.
  • Explore the environmental impact of materials like polycarbonate, particularly regarding bisphenol A.
USEFUL FOR

Homeowners, DIY enthusiasts, and anyone interested in outdoor construction or material selection for weather-resistant applications.

Hi all,

I'd like to know what is the most transparent material that;s waterproof, but not as brittle as glass. I want to put a "roofing" on a section in my balcony where I usually hang my clothes to dry and disinfect them under the sun, but I don't want to run all the way up everytime it rains. and the reason for "not brittle as glass" is that some times (not often), we have hails, ice cubes raining down from the sky.

thanks

Lucite, perhaps?
 
Corrugated or multiwall polycarbonate sheets are often used for this. They can be obtained from large hardware type stores (Home Depot, Lowes, etc.).

WRT disinfecting, Polycarbonate passes UV, lucite (plexiglas) does not.

thanks for the reply. but I read that polycarbonate distort and degrade under constant exposure to the elements. and sometimes, they also yellow overtime. is this true?
thanks
 
Tempered glass, as used in autombile windows and in skylights in buildings.

I had some outside for a few (3 or 4) years covering a large fish tank. I don't recall it yellowing or distorting. I did have it on a frame however.
 
You might be better off building something that you can draw out for when it does rain. Even if you put something permanent up, you are still blocking some air flow to your laundry when the protection isn't needed. And it won't look very nice.

Why can't you just go and pin them on a clothes line outside? I was helping with this on the lower lines when I was, like, at least 5/6 years old. You can make a secret hiding spot from others using sheets. When it starts sprinkling, just start running and jerking the clothes off the line. If it's close to your living quarters, then it would be quicker than that. Any quicker and you are better off getting a dryer.
 
Clear plexiglass would work fine for that.

Isn't that the same thing as Lucite?

Poly(methyl methacrylate) = Acrylic = the trade names (lucite = plexiglas = Prespex = Acrylite)

polycarboante = Lexan (trade name)
polycarbnonate is stronger and light passes through it better, but is made with and could release bisphenol A.

1. how large is this area ? 2. how many days of sunshine -time duration-sun angles 3. slope angle off roof 4.humidity-temp 24/7-etc.-etc. 5.cloth load! - remember ! our universe is just one of the many bubbles out there.
