The Texas Tech Athletic Training Facility is the largest vinyl polyester fabric air supported structure roof in the world.  Fiberglass has been more traditional until Texas Tech University, along with ASATI, constructed this Dupont Tedlar sports facility.  The fabric is highly translucent, providing over 1000-foot candle of natural light within the structure during daytime hours.  The total roof structure is constructed with a dual wall system, which provides excellent thermal insulation without sacrificing the natural light penetration for allowing the facility to be used without the high energy cost for operating artificial lighting.

ASATI engineered, manufactured, and installed this facility in 1985. The total 100,000 square foot structure roof was manufactured in three sections.  The entire roof structure was installed and ready for use in three days after site delivery. The roof structure final assembly weights 30,000 lbs. and is engineered to withstand Lubbock, Texas code wind speeds of up to 120 mph.
