• Always install the product with the reflective side facing out. This allows code officials easy access to code information on the product.
• Staple Reflectix® RAP (Bubble) between the floor joist, or to the side of the floor joist. Open web trusses are acceptable.
• Start at the end of the house and staple Reflectix® RAP (Bubble) to the sub-floor just behind the return air grate.
• Staple Reflectix® RAP (Bubble) to the bottom of the floor joist every 2" to 3". Additional approved attachment methods include: steel staples, sheet metal screws and roofing nails.
• Seal the seams with UL181 tape with an acrylic adhesive.

• Sheet Metal has traditionally been used for both stud cavity and joist space plenums. However, code does not specify types of materials allowed for panning.
• Check your local codes before installation for compliance in your area.
