O'Sea® Polished Vinyl Window Material is a 40 gauge premium press polished window material with exceptional optical clarity and durability. O'Sea is a marine grade window material manufactured from thermoplastic clear vinyl material and formulated for maximum UV stability. The window material is first coated to provide a scratch- and chemical-resistant barrier, then pressed and last it is highly polished resulting in a soft, flexible, press-polished sheet. Chemical resistance includes suntan lotion, insect repellent and jet fuel vapor. This clear vinyl window material is perfect for marine windows, marine cabin enclosures, dodgers, awnings and other marine and automotive applications requiring the best in clarity and durability.

Please Note: The manufacturer lists the size of the sheet as 54" x 110", however we have found that the sheet size varies up to 3 inches in length and 1 inch in width.


Baste window material in place with Seamstick over the fabric. Sew the window in place using a #18 or #20 needle and V-69 or V-92 thread. After sewing, use scissors to trim away the fabric from the window. Bind the raw edges with binding for a more finished appearance.

Pro Tips:

  • Due to a slight bluish tint, we recommend pairing this product with other O'Sea or Regalite products.
  • During fabrication, it is recommended that you use 3M™ brown tape only to avoid damaging the material.

Great product

Heavy but still ready to roll and to sew. Very clear.


Excellent window material

I was very pleased with the O'sea polished vinyl window material. It was very flexible and easy to work with. This is a very high quality clear window material.

Great product

I have used 4 rolls of O'sea and am very happy. It is very easy to sew and the unusable edge is very small, maybe 1/8-1/4" at the most.


Do it yourself, you will love the results and savings.

Exceptionally good product, easy to work with and the clear finish looks great on the boat. The cost savings of making my own windows compared to having them professionally made was tripled.


High Quality Product

I debated about my purchase of this material for my flybridge front windows. I had replaced these windows 2 years ago with another vinyl window product and was disappointed when the windows became foggy in such a short period of time. The O'Sea material was a lot more expensive and I needed less than half of the roll for this project (wish product could be purchased in length increments like other materials). I found the material was very easy to work with and the on-line instructions from Sailrite on making windows and installing zippered cutouts were excellent. I am really happy with how the finished project came out using this vinyl material and I hope it lives up to it's claim to be scratch and chemical resistant and that it will stay durable and clear. I only gave it a 4-star rating because the material can not be purchased by a specifed length. If I would have replaced all the windows in my canvas enclosure it would have required 6 1/4 yards of material. I would have had to purchase 3 rolls of vinyl because 2 rolls would have been 5" too short.

Didn’t meet expectations

I choose this product in place of strataglass I found it to be more brittle and developed memory I’m sticking with strataglass
