    Karah Card and Don Walker planning studio floor pads, Nov.1996

Here are Chattanooga artist Lawrence Mathis' 1993 original drawings for the Split Tree studio, which was originally slightly smaller than the present 60' x 36' floor space--to which was added in 1996 an 8' north deck and 10' south deck.  The sliding glass doors were added in Spring 1996, just before the Fool's Fest was moved from Hidden Hollow to Split Tree.  Prior to the glass doors, large blue plastic tarpaulins were stretched between the 6x6 posts to keep out the rain; they were rolled up when dances were held in the studio.  Lawrence and Mada Mathis were very generous and influential in the formative stages of what became Split Tree and we deeply appreciate their contributions as volunteers and as neighbors. 

Several people have asked about the floating floor itself and detailed information can be obtained from John Prater of Prater Construction in Chattanooga, TN (area code 423).  Daniel Lee, a Chattanooga builder, was the primary carpenter, assisted by Don Walker and many more volunteers, such as the talented Karah Card in the photo above with Don.   See more photos on the Photo Album page for the people who finished the floor on Thanksgiving 1996.

Briefly, the floor is of North Carolina 3rd-grade hard maple, tongue-in-groove and cost about $5,000.  Every 14th board is spaced slightly to allow for expansion and contraction.  Just under the maple is a layer of  roofing felt.  This flooring is stapled to a layer of 1/2" CBX plywood.  Under this diagonal layer of 4x8' plywood are 3x5" rubber pads, stapled underneath every 12 inches, starting 6 inches from the edge (see photo at top).  These hollow pads rest loosely on top of another diagonal layer of 1/2 inch CBX plywood on top of a plastic vapor barrier.  That layer rests on the original 3/4" plywood flooring.  The effect is that of a springy gym floor and movement is easy on the feet, ankles, and knees.  The model we followed is at Ann Law's Barking Legs Theater in Chattanooga, TN.  

Volunteers laid the plywood and racked the maple flooring, then stapled it during the last two weekends in November 1996.  The Prater Construction Co. was paid to sand and seal the floor with 2 layers of water based polyurethane  topping.  The friction is perfect for both social dancing, using soft-soled shoes, and body contact movement work.  However, it would not be suitable for classical ballet use with out resin, which we would would not allow.  The floor can be mopped with water periodically and is kept clean with large dust mops.

The "floating" floor is primarily for full body movement work on the floor, such as contact improvisation, and social dance, not for painting or any activity that would add grit or risk paint falling on the floor.  The glass doors make it completely unsuitable for basketball, etc.  The room is heated with a large overhead propane, vent-free radiant heater.  Double squirrel fans in each gable vent warm air, and in 2000 air conditioning/heating was added with on-top metal/foam roof insulation added in 2485.
