INTRODUCTION


RAUPANEL SYSTEM

- Ideal for kitchens, baths, entire house- May be used in floors, walls, ceilings- Efficient- Low-profile - Lightweight- High performance- Fast response time

- Nighttime setback is an option- Solar gain problems are reduced

- Easy to plan- Easy to install

ADVANTAGES OF THE RAUPANEL ALUMINUM SYSTEMFOR THE DESIGNER


RAUPANEL SYSTEM

- Higher efficiency thanks to reduced downward heat transfer and aluminum panels- May eliminate insulation under subfloors (over heated space below)- May eliminate double baseplates due to reduced floor thickness - No special equipment necessary (no “wet” thermal mass)- Faster response time than an overpour (lighter weight)- Suitable for both retrofit and new construction- No complicated scheduling and preparation- Fewer changes to overall construction- Eliminates other trade (thermal mass)- Design flexibility, easier to zone - Available when you want it- Everything is boxed- A complete system- Easy to carry- Low profile

ADVANTAGES OF THE RAUPANEL ALUMINUM SYSTEMFOR THE CONTRACTOR

RAUPANEL INSTALLATION

1. Lay out Return Bends and Furring Strips (for 8” spacing)

Note: Be sure that subfloor is clean before installation of panels

2. Drop Aluminum panels onto floor;align into notches with 8” Bends

COMPONENTS FIT TOGETHER AS A SYSTEM (1-2-3)



Note: Leave 1/16” to 1/8” gap between ends of panels to allow for possible house movement or shrinkage




3. Pipe is “walked into” the groove; a rubber mallet may be needed to set it in

Note: Be sure that panel grooves are clean before installation of pipesNote: No silicone is used to fill grooves. Pipes will not pop out when properly installed




WARNING! Wear gloves and eye protection when handling pieces

DEBURR FIELD CUTS WITH DEBURRING TOOL IN THE GROOVE



1. Nail-down hardwood flooring (over suspended subfloor)2. 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

THE NEXT STEPS:THE FOLLOWING INSTALLATION GUIDELINES APPLY TO VARIOUS FLOORING CHOICES



1. Install panels and pipes following the first Steps 1-2-3

2. 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”

NAIL-DOWN HARDWOOD FLOORS

Note: Panel system may be loose and noisy until all hardwood is properly secured

It is recommended to use 8” spacing with furring strips when installing nail-down hardwood


RAUPANEL INSTALLATIONNAIL-DOWN HARDWOOD FLOORS

Note: Panel system may be loose and noisy until all hardwood is properly secured

- 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 ring-shank nails, not smooth nails, which could work loose

- Nails must be long enough

RAUPANEL INSTALLATIONNAIL-DOWN HARDWOOD FLOORS6” SPACING INSTALLATION WITH HARDWOOD

- If 6” spacing is necessary for heat load, this installation is possible- Aluminum panels and plywood pieces must be fastened to subfloor following instructions- Nail or staple hardwood flooring through aluminum panels into subfloor, every 6”- Must use 2” or longer cleats, nails or staples- It is recommended to use 5/8” or 1/2” thick hardwood to ensure most secure fastening

6” spacing


RAUPANEL INSTALLATIONNAIL-DOWN HARDWOOD FLOORS6” SPACING INSTALLATION WITH HARDWOOD

- Must use 2” or longer cleats, nails or staples for good bite into subfloor- With 3/4” solid hardwood, a 2” fastener will have 5/8” length bite into subfloor- It is recommended to use 5/8” or 1/2” thick hardwood to ensure most secure fastening

2” Long


RAUPANEL INSTALLATIONTYPICAL INSTALLATION WITH NAIL-DOWN HARDWOOD FLOORS



1. Install panels and pipes following the first Steps 1-2-3

2. Screw or nail Return Bends and Furring Strips to subfloor (use maximum 8” spacing between screws or nails)

3. Fasten Aluminum panels 3 times per side - Total 6 per panel per 6-foot length

4. Install flooring as per manufacturer’s recommendations- Avoid contacting glue onto pipes

FLOATING AND GLUE-DOWN FLOORS

- Use 8 screws per Return Bend*- Use 5 screws per Furring Strip*- Use 6 screws per Aluminum Panel*

*Per full length componentsNote: Always feel free to add extra fasteners if movement or noise is suspected


RAUPANEL LAYOUTSTYPICAL INSTALLATION WITH FLOATING FLOORS


RAUPANEL INSTALLATIONTILE FLOORSUSING MORTAR BOARD AS ALTERNATIVE TO DIRECT PLACEMENT OF THINSET

Sample cutaway floor:- 1/4” thick mortar board

installed directly over RAUPANEL at 6” o-cspacing with maximum 8”grid spacing for screws

- Tile placed on thinset over mortar board

Note: When using panels at 6” o-c install screws at 6” o-cspacing also to avoid hitting pipes


RAUPANEL INSTALLATIONTILE FLOORSUSING MORTAR BOARD AS ALTERNATIVE TO DIRECT PLACEMENT OF THINSET

Sample cutaway floor:- 1/4” thick mortar board installed directly over RAUPANEL at 6” o-c spacing - Tile placed on thinset over mortar board- Panels installed directly under shower pan for warmth



- 1/4” or 3/8” mortar board with 8” maximum grid spacing for screws

TYPICAL INSTALLATION WITH TILE FLOORS



1. If necessary, level floor with self-leveling thin-set2. Cover existing slab (or above the leveling layer) with a poly or tar paper vapor barrier (not

aluminum) to block possible moisture permeation3. Install panels and pipes following the first Steps 1-2-34. 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

OVER EXISTING SLAB



- REHAU Reference Documents (CD) has Detailed Installation Drawings for installation techniques

- Example:

SEE “REHAU REFERENCE DOCUMENTS” CD


RAUPANEL LAYOUTS

- 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

HALLWAYS SHOULD BE FILLED WITH RAUPANEL TO AVOID COLD FLOORS,BUT THERE MAY NOT BE ENOUGH SPACE FOR ALL CIRCUIT TAILS IN HALLWAYS

ROUTING PIPE TAILS TO MANIFOLDS

- Note: These pipes are too close to the end of the panels. Not a good example

ROUTING PIPE TAILS TO MANIFOLDS

- Route pipes through floors and joist cavities to get to manifolds

JIGSAW A SLOT IN THE FLOORRUN PIPES THROUGH THE JOIST CAVITIES TO MANIFOLD


- Avoid routing pipes to manifold on the subfloor – go below

ROUTING PIPE TAILS TO MANIFOLDSRUN ALL THE PIPES IN ONE NARROW AREA? NO! THIS METHOD IS NOT RECOMMENDED (HOT SPOT)


WALLS AND CEILINGS

- Use panels for walls where supplemental heat is needed- Very nice in bathrooms, tub/shower walls, behind large mirrors, tubs

APPLICATIONS IN WALLS AND CEILINGS

Interior drywall


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

APPLICATIONS IN WALLS AND CEILINGS


WALLS AND CEILINGSINSTALLED IN A WALL SURROUNDING A SHOWER

Sample cutaway wall:- 1/4” thick tileboard board

installed directly over RAUPANEL at 8” o-c spacing

- Tile is placed on thinset over tileboard

- Furring strips are used on stud edges above panels to flush out the walls before tileboard installation


WALLS AND CEILINGSINSTALLED IN A WALL SURROUNDING A SHOWER

Sample cutaway wall:- 1/4” thick tileboard board
