Preparation

The concrete floor and foundation should be relatively dry and free of large cracks, excessive moisture penetration or flooding problems prior to installing Barricade Insulated Subfloor panels. Barricade is not meant to be a replacement for good foundation maintenance. Any moisture issues including leaks, excessive moisture, mold/musty spots, foundation cracks, window leaks, exterior drainage or hydrostatic pressure issues, should be resolved prior to Barricade Insulated Subfloor's installation to avoid potential contamination to the finished project and surrounding building materials. Any dips or low spots in the concrete surface greater than 1/4" should be trowelled level with a Portland cement compound or leveled with a self-leveling compound to ensure an accurate installation. Determine the number of Barricade Insulated Subfloor panels and leveling kits needed to complete the room(s). To do this, calculate the total number of square feet of your floor (length x width). Divide the number by 3.3. This formula allows for a percentage of additional panels normally used as partial waste, while cutting around pipes and other obstacles. Please note: The actual panel dimensions are 7/8" x 23.5" x 23.5". Check out the Barricade Insulated Subfloor Calculator!

Subfloor panel preparations

• Make as much space as you can spare in the area where you will be laying the Barricade panels. Remember, you'll need space to stack the panels, which should be away from where you begin laying the floor.
• Sweep or vacuum the entire surface to remove any debris that may interfere with the proper seating of the Barricade panels. Visually inspect the floor area for bumps or ridges that will need to be removed before you begin.

Installation tools needed

• A circular saw and/or jigsaw
• A hammer or rubber mallet 
• A carpenter's square
• A tapping block and pull bar
• Barricade leveling kits (based on the formula 1 kit / 60 panels)
• A sufficient quantity of 1/4" flooring spacers, to create the proper expansion space between the panel edges and the walls, or other fixed surfaces
• A dust mask or respirator for cutting panels outside
• A pair of safety glasses for eye protection
• Barricade Insulated Subfloor is a floating subfloor. However, in some instances, we suggest that you fasten the panels to the concrete floor.
• We recommend that the panels have a 1/4" space away from all perimeter walls and room obstacles, such as support posts or stairs, to allow for airflow and some expansion. Check with the lumber department for 1/4" wood strapping, off cut stock or other inexpensive 1/4" dimensional lumber that you could use as spacer material.
• For homes where the basement may have an existing subfloor or covering over the concrete surface that may trap, block or absorb moisture, we recommend that it be removed prior to installing the Barricade Insulated Subfloor panels.
• Access to floor drains or clean-outs should be maintained and not restricted. Be sure to check with your local authority for building code recommendations before covering any basement floor drain or clean-out access. It is not a requirement to install a basement drain prior to installing a Barricade Insulated Subfloor. If you install Barricade Insulated Subfloor panels over a drain access, cut an access opening in the panel that rests over the drain. You can either reinstall the cut piece to cap off for future removal and maintenance or take the drain cover from the existing opening and use to cap off the top of the Barricade material or finished flooring material to allow for access.
• There are many conditions which can contribute to excessive moisture in a basement - house location, soil conditions, poor exterior drainage, construction, lack of or failure of waterproofing methods, hydrostatic pressure etc... Maintenance, repair and understanding how to control these factors will help to limit and prevent leakages or flooding from occurring.

Setting up the layout

• First, choose the longest straight wall as your starting wall. Select one of the corners on this wall as the place to lay the first panel. Choose the corner of the room that will result in the least amount of cutting required for the entire room.
• Measure the distance between your beginning point and end of the wall where the first panel run will terminate. Trim the starting panel back to allow for at least a 3" panel section at the end of the first row.
• Check your starting corner for squareness. If your starting corner is not at a 90o angle into the room, then the wall edge of your first row of panels will require cutting to ensure squareness of the panel to the inside of the room.
• Begin in your selected 'start' corner of the room and lay the 1/4" spacing material along the two walls. Eventually you will have these spacers placed around the entire perimeter of the Barricade area. (If you're working in a basement where there is already a stud wall around the perimeter of the basement, apply the same 1/4" spacers between the panel and the stud wall.)

Installation

• In your selected starting corner, lay the first panel with the tongue side flat against the spacers. Slide the next panel into place by connecting the tongue side into the groove of the first panel. Use a tapping block with a hammer to make sure this second panel is snug to the first panel, and to the wall spacer. Repeat this panel placement the length of the wall.
• Once you reach the last panel in the row, chances are good that you'll have to cut the panel to fit. Measure to fit tight against the 1/4" spacer. Cut the panel to size and press into place with the pull bar. Ensure the last panel is at least 3".
• Before you start the second row, check the first row for leveling and adjust any panels that bounce, with a Barricade leveling shim. Note that each row of Barricade Insulated Subfloor should be staggered at their seams.
• Row #3 looks just like Row #1. Starting Row #3 with a full size panel will create the natural seam offset. Row #4 would be staggered again as in Row #2.
• The first three rows are the most critical to the success of a well formed subfloor. Take your time, and place down one row at a time installing tightly to prevent any seam separation.
• Continue to install the floor, checking for leveling and adjusting with Barricade leveling shims as necessary. Work from one side of the room to the other, one row at a time.
• When you reach the last row to complete your installation, chances are good that you'll have to cut the panel to fit. Measure for fit, keeping in mind the additional (1/4") expansion space from the wall that is required. Cut the panel to size and press into place with the pull bar.
• When all of your panels are in place, you may be able to remove the 1/4" spacers from around the perimeter of the room depending on the finished flooring application.

The Leveling Kit

• The leveling shims have been designed for use with the Barricade Subfloor panels for areas where your basement floor is uneven. They simply fit over the cleats on the underside of the Barricade Subfloor panels, raising the panels to the desired level.
• Place the leveling shims over the area of the panel where you feel the height adjustment is necessary. Slide the square until it 'nests' or 'cups' into place on the underside of Barricade Subfloor panel.
• In some cases, you may need to stack 2, 3 or more leveling squares together to get the right height adjustment needed to level the panel. NOTE: Any dips or low spots in the concrete surface greater than 1/4 should be trowelled level with a Portland cement-based compound.

Making Interior walls

• An interior stud wall can be set right on top of your new Barricade Subfloor and is in fact, the preferred method of installation. Install your 2X4 frame directly on top of the subfloor, measuring for a "snug" fit between the subfloor and ceiling.
• Once the frame is in position, simply screw the bottom plates of the 2X4 frame to the Barricade panels, using 2" wood screws. To finish the anchoring process, we suggest fastening the bottom plate to the concrete floor using either 3" concrete nails or concrete fasteners.
• Only minimal fastening to the concrete is required. For example, for every 8' length of base plate, install only two concrete anchors. Note: If you are planning to use metal studs in place of wood, the base track for the studs should be affixed to the Barricade Insulated Subfloor panels with 5/8" wood screws as a maximum. Metal stud base plates should be anchored in concrete every 2' when installing over Barricade Insulated Subfloor panels.
