We are often asked which of the three weights of plastipane window material offered in our catalog is best. There is no definitive answer to that question. 20 gauge plastipane is the least expensive and offers the most options in size since it comes on a large roll and long lengths can be ordered. It is also more easily rolled up because it is not as thick and thus more flexible than the heavier weights of plastipane.
20 gauge, however, is not as optically clear as the heavier 30 and 40 gauge weights which are often called "pressed polished sheet goods". These weights are produced in various sheet sizes and, although their extra weight makes them stiffer and thus harder to roll up, they generally last longer.
All three weights can be sewn on a home sewing machine using a size V-69 or V-92 UV resistant sailmaker’s thread. Use #129 acrylic basting tape to hold the plastipane in place on the canvas while sewing. Do not cut away the canvas (or, if you are replacing a window, do not remove the old window) until the plastipane is sewn in place. An easy way to hide the raw edges of the canvas after it is cut away is to sew a binding tape around it. This can also be done on the other side to hide the raw edges of the plastipane.
Note: 30 and 40 gauge plastipane is also produced as rolled goods, i.e., on a large roll. But, for a number of years, we have found these weights of rolled goods to be too flawed to sell. If quality improves, we will add them to our inventory. |
