Roll-A-Cover's pool enclosures greatly enhance pool areas and allow for year-round use. Homeowners, condominiums and hotels are unable to use their outdoor pool when the weather is inclement or during the colder months without a pool enclosure. Made with 10mm polycarboante, 1/4" tempered glass, and heavy duty aircraft aluminum rafters, the retractable room protects the pool from debris and is climate controlled. It can also withstand snow and wind loads throughout North America. A pool enclosure enhances the value of your swimming pool and allows for year-round swimming over your pool investment.
