Radiant heating and cooling panel and method of manufacturing

A method of manufacturing a radiant panel comprising the steps of:

• forming an extruded, aluminum panel;
• providing upstanding saddles having a generally circular, concave contour and adapted to receive a tube;
• providing the saddles with a top, terminal portion located in a first plane;
• extruding channels in the panel;
• providing the channels with a U-shaped opening with an irregular, inside surface adapted to receive a fastener;
• said upstanding channels having a top located in a plane above the top of the saddles and above the first plane;
• positioning a crossbrace across the panel and contacting the tube with the crossbrace and holding the tube in the saddle;
• fastening the crossbrace to the upstanding channels and contacting the top of the channels and orienting the top of each channel in a common plane and thereby level the connected panels;
• inserting a fastener through said crossbrace and into the associated channel;
• tightening the fastener into the channel and urging the crossbrace into the tube to hold the tube securely in the saddle;
• locating an adhesive in the saddle;
• placing a tube in the saddle;
• pressing the tube into the saddle and displacing a portion of the adhesive, causing it to rise up the saddle in contact with the saddle and tube.
