Performance Surface Construction
The performance surface is normally of vinyl or hardwood, engineered wood or laminate. For dance the surface may be replaceable so for instance a theatre can adapt easily to either ballet or tap dance, these are normally made of vinyl sheeting. Hardwood is however preferred for tap dance. Some sports have extra requirements like spike resistance or a standard ball bounce.
Roll-up vinyl sheeting normally consists of:
- A thin top wear layer that also has UV light protection. Ultraviolet light rapidly degrades vinyl. This layer has to provide the proper traction and tends to be matte rather than shiny as for domestic vinyl.
- A layer of vinyl which supports the wear layer. This also provides the main colour.
- A woven fibre interlayer. This stops the floor deforming and also provides some area elasticity.
- A bottom layer of foamed vinyl which provides the softness.
When rolled up the vinyl should not be bent sharply - it should be on rolls. When there are a number of different surfaces for a hall these can be kept on special storage carts which keep them separate rather than lying on each other.

Famous quotes containing the words performance, surface and/or construction:
“So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.”
—Melinda M. Marshall (20th century)
“We’ve forgotten what it’s like not to be able to reach the light switch. We’ve forgotten a lot of the monsters that seemed to live in our room at night. Nevertheless, those memories are still there, somewhere inside us, and can sometimes be brought to the surface by events, sights, sounds, or smells. Children, though, can never have grown-up feelings until they’ve been allowed to do the growing.”
—Fred Rogers (20th century)
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
