Floating and glue-down flooring (over suspended subfloor) 3. Carpet and vinyl (over suspended subfloor) 4. Tile (over suspended subfloor) 5. Installations over concrete slabs Notes: - These are general guidelines for installation of RAUPANEL under common floor coverings - Certain floor coverings may have specific installation requirements which are not covered in this document - It is the responsibility of the installing heating contractor to work with other trades, including the installer of the finished floors, to ensure that the flooring manufacturer s requirements are adhered REHAU 26-Mar-10 - Page 12

RAUPANEL INSTALLATION NAIL-DOWN HARDWOOD FLOORS 1. Install panels and pipes following the first Steps 1-2-3 2.

11 RAUPANEL INSTALLATION NAIL-DOWN HARDWOOD FLOORS 1. Install panels and pipes following the first Steps Screw or nail Return Bends and Furring Strips to subfloor (use maximum 8 spacing between screws or nails) 3. Let the Aluminum panels float between plywood panels no need to screw these down 4. Install hardwood directly over RAUPANEL system (perpendicular in direction to panels) 5. Nail or staple hardwood boards into plywood components or through aluminum/into subfloor if necessary - Fasten boards every 6-8 It is recommended to use 8 spacing with furring strips when installing nail-down hardwood Note: Panel system may be loose and noisy until all hardwood is properly secured REHAU 26-Mar-10 - Page 13

RAUPANEL INSTALLATION NAIL-DOWN HARDWOOD FLOORS - Minimum 8 screws per Return Bend - Minimum 5

then more fasteners may be required to prevent noise - Fasten as necessary - Screws: - Use

nails, not smooth nails, which could work loose - Nails must be long enough 8 spacing 8

12 RAUPANEL INSTALLATION NAIL-DOWN HARDWOOD FLOORS - Minimum 8 screws per Return Bend - Minimum 5 screws per Furring Strip - If subfloor is not even or has excessive deflection ( bounce ), then more fasteners may be required to prevent noise - Fasten as necessary - Screws: - Use fine-thread drywall screws or deck screws - Nails: - Use rough roofing nails or ringshank nails, not smooth nails, which could work loose - Nails must be long enough 8 spacing 8 spacing Note: Panel system may be loose and noisy until all hardwood is properly secured REHAU 26-Mar-10 - Page 15

22 RAUPANEL INSTALLATION OVER EXISTING SLAB 1. If necessary, level floor with self-leveling thin-set 2. Cover existing slab (or above the leveling layer) with a poly or tar paper vapor barrier (not aluminum) to block possible moisture permeation 3. Install panels and pipes following the first Steps Depending on the flooring to be used, follow that typical installation technique: - When anchoring panel pieces, overlayment or mortar board, use proper fasteners for anchoring to concrete (ram-sets may work; masonry screws do work) - Be sure not to penetrate any existing pipes, cables, etc. in existing slab floor - Follow all safety precautions for using concrete fasteners REHAU 26-Mar-10 - Page 30

24 RAUPANEL LAYOUTS HALLWAYS SHOULD BE FILLED WITH RAUPANEL TO AVOID COLD FLOORS, BUT THERE MAY NOT BE ENOUGH SPACE FOR ALL CIRCUIT TAILS IN HALLWAYS - Sometimes there are too many pipes to fit in a hallway, all within the panels (too many circuits to supply) - May have to install some pipes outside panels, or you may have to install some pipes through the subfloor to reach the manifold REHAU 26-Mar-10 - Page 38

31 ROUTING PIPE TAILS TO MANIFOLDS RUN ALL THE PIPES IN ONE NARROW AREA? NO! THIS METHOD IS NOT RECOMMENDED (HOT SPOT) - Avoid routing pipes to manifold on the subfloor go below REHAU 26-Mar-10 - Page 45

32 WALLS AND CEILINGS APPLICATIONS IN WALLS AND CEILINGS - Use panels for walls where supplemental heat is needed - Very nice in bathrooms, tub/shower walls, behind large mirrors, tubs Interior drywall REHAU 26-Mar-10 - Page 47

WALLS AND CEILINGS APPLICATIONS IN WALLS AND CEILINGS - Use panels for walls or ceilings where floor space is limited (bathrooms, kitchens, mudrooms) - May be the same circuit of pipe, same water

33 WALLS AND CEILINGS APPLICATIONS IN WALLS AND CEILINGS - Use panels for walls or ceilings where floor space is limited (bathrooms, kitchens, mudrooms) - May be the same circuit of pipe, same water temperature - Keep panels within 3 feet of floor to prevent future pipe punctures - Use furring strips on edges of studs above panels to make walls flush for drywall - Insulate behind panels at outside walls or ceilings REHAU 26-Mar-10 - Page 48
