Around 2mm Fibreglass Laminate A two-layer laminate has a thickness of around 2mm. The individual fibers that make up the material are about as thin as human hair. Fiberglass is used in everything from flooring to boat hulls, but it's most commonly seen in glass windows and doors. Fiberglass is also used in composite materials such as tennis rackets and golf clubs. When you walk on a carpet made from fiberglass insulation, you're walking on thousands of threads held together by a binder. That's why these carpets are more durable than traditional rugs and can be cleaned with a vacuum cleaner or washed in a washing machine. The fiberglass thread that makes up the carpet is only about 1/8th of an inch thick. It's tough enough to withstand traffic stains and high-traffic areas of the house. These threads are spaced about 3/4 inch apart, which is why your feet feel cool when you first get out of bed in the morning and warm when you go back to sleep at night. Carpets with fiberglass threads are available in patterns that mimic natural grass or wood floors.
