1/5/2024 0 Comments Paint canvas awningsHigh-quality laminates continue to be useful today in rigid, fixed frame awnings and tension structures. Typical weight of these laminates are 10 ounce to 19 ounce per square yard. The vinyl laminate starts with a polyester scrim sandwiched between two or more layers of vinyl and bonded together with high pressure and heat. Vinyl laminates became available after the end of WWII. Painted fabrics and vinyl are still used in some applications today. Typically, awnings used 12 ounce material, with marine applications and seaside awnings using heavier 16 to 19 ounce fabrics. They were called "painted fabrics" because most awnings were acrylic coated. The History of Treated Canvas and Painted Fabrics: 1920įrom the 1920's through the '70s, more weather resistant materials became available, usually cotton / polyester blends or 100% polyester with various treatments, such as coatings of acrylic paint, vinyl, or polyester resin. One yard of 12 ounce material weighs 12 ounces, one yard of 32 ounce material weighs 32 ounces. Back when we started, up until the Roaring 20's, all awnings were made from 12 ounce cotton and were available in two colors: natural or khaki. Water resistance was with a paraffin treatment (wax)! You can still get 100% cotton canvas today in natural color and a few dyed colors. It would shrink when it got wet, up to 10%. Canvas meant raw untreated material, not waterproof, no ultra violet light inhibitors. Like metal gauge thickness, the lower the number the thicker the material. Back when we started in 1897, they used to stencil a duck on the outside of the roll with a number - a number duck - that goes from #12 (11.5 ounce) up to #2/0 (32 ounce).
