Isinglass is a clear window material for boats.
Isinglass is an older term used for a clear plastic material that was usually sold in sheets or rolls.Our O'Sea and Regalite brands would be similar today.There are clear vinyl sheets that are used for making boat windows.The clearest product for boat windows is our marine grade clear vinyl, which is made to stand the test of time.
Have been asking for years for a Press Polished Vinyl with a harder durometer because they have always liked the quality of Regalite.040.Last year's test sheets and production run sheets were used by O' Sullivan Films for the Firma product.The hand is firm.
We go with the best in the business when we want consistent optical clarity and a long lasting clear marine vinyl.
