Teragren Portfolio Collection Installation Guidelines - Bamboo Flooring
Teragren Portfolio Collection featuring Välinge-patented modified 2G fold-down system
Measure the room so that the quantity of flooring required is known (length x width = square feet). If the last board required is too narrow in width, it may be necessary to install length-wise cut boards on both sides of the room to give it an overall balanced look. Ensure that the floor will fit under doors and skirting strips. Existing skirting strips may have to be removed during installation to allow for the expansion perimeter. Ideally, the flooring should be installed parallel to the longest dimension of the room. In a square room, the long joints should (preferably), follow the path of the incoming light. Allow for a minimum expansion space of 1/2” (13mm) around the perimeter of the installed flooring. For floors larger than 16’ (4.87 meter) in any one direction, leave an additional expansion space of 1/8” (3.2mm) on the edges for each 48” (1.2meter) of installed flooring. For example, a 24’ (7.3 meter) square room would require about 3/4” (19mm) expansion on all sides. Rooms larger than 40’ (12.2 meters) wide (boards running length of room) require an expansion joint in the middle of the room such as could be provided by leaving an intentional gap covered by a t-mold (or other flat molding) or other accessory piece. Any rooms that are not square (such as a T, L, F, or U shaped room) must have non-parallel areas separated by an expansion joint. All door opening must have an expansion joint between rooms. Under no circumstances should the floor’s ability to move freely be restricted.
First Row: Start in a corner of the room with the locking strip (lower edge of the lock) facing into the room (see picture #1). Using spacer wedges, maintain a 1/2” (13mm) gap between the wall and the edges of the planks being installed. Install the first plank. Install the second plank (see picture #2), pressing the short end of the second plank against the leading edge of the first plank and then, in one movement, laying it down flat (see picture #3) to engage the locking mechanism. Ensure that the edges of all planks being installed are parallel and even. Continue with this method until you are ready to install the last plank of the first row.
Carefully measure the required length of the last plank in the row, allowing for a minimum of a 1⁄2” (13mm) gap at the end of the row (see picture #4). Cut the last plank of the first row to size using a saw with a carbide blade (see picture #5), then install as done for the previous planks, leaving a 1⁄2” (13mm) gap at the end. After the first row is complete, ensure that all edges are perfectly even and parallel. Note: It is practical to fine-tune the gap between the long sides and the wall later, after the first three rows have been laid.
Second Row: Start the second row beginning with (if available) the piece left over (cut off) from the first row (see picture #6 - piece must be at least 36” (91.4cm) in length). If the piece is too short (or if there is no leftover piece), start with a new board, cut in half. Always ensure that the end joints (between planks in adjacent rows) are staggered at least 10" (25.4cm) apart (see picture #7).
Maintaining a 1⁄2” (13mm) gap between the end of the plank (row 2 plank 1) and the wall using a 1⁄2” (13mm) spacer, begin the second row by inserting the long edge of the locking mechanism of the first plank (row 2 plank 1) into the long edge of the locking mechanism of the adjacent plank of the first row. Push the plank forward and press down at the same time to fully engage the locking mechanism (see picture #8). With the plank resting flat on the floor, ensure there is no gapping at the joint between it and a first row. If necessary, use a tapping block to ensure that the plank’s locking mechanism is fully engaged and that there is no gap between it and the adjacent plank. To install the second plank (row 2 plank 2), place the long edge of the plank into the adjacent plank of the first row. Slide this plank to the left until the short end of the second plank is flush against the leading edge of the first plank (row 2 plank 1). Then, in one movement, lay the plank down flat, ensuring that there is no gapping on either the short end or the long side of the plank. Use a rubber mallet and tapping block to correct any gapping. Note: If gapping cannot be corrected by a rubber mallet and tapping block, ensure that there are no splinters or other obstructions keeping the locking mechanism from fully engaging.
Installation Around Pipes or Columns
Drill holes and saw out flooring as required to make room for any exposed structure or pipe. Note: holes around pipes or other items must be at least 3/4” (19mm) greater in diameter than the pipe or structure.
Installation with Transition Pieces
Flooring must be allowed to float freely underneath the overlap portion of the transition piece. To ensure freedom of movement, cut or chisel off tongue as required allowing unrestricted movement of the flooring under the transition piece.
Radiant Heating Systems
Teragren Välinge 2G Fold-Down Bamboo Flooring is suitable for installation over radiant heating systems capable of maintaining a surface temperature at or below 85°F. The radiant heating system needs to be in operation for at least 7 days prior to installation, shut off 4 hours prior to flooring installation, and then returned to operation once the installation is complete. Please refer to www.radiantpanelassociation.org for more information. It is up to the owner/installer to confirm the suitability of any radiant-heating system for the intended end- use. The selection and use of any radiant heating system is at the sole discretion and responsibility of the owner/installer.
