GENERAL INSTALLATION REQUIREMENTS FOR ALL FLOORING OVER WOOD SUBFLOOR
1) Do not install Infloorboard™ without an accurate room-by-room heat loss analysis of
the structure to be heated and a design/layout for Infloorboard™ that takes into account
the resistance and heat transfer of the actual floor coverings. If Infloorboard™ cannot pro-
vide all the necessary heat, make provisions for additional back up heat.
2) Thoroughly clean all surfaces that Infloorboard™ will be applied to. The surface to
which Infloorboard™ will be attached must be flat and dry prior to installation. See
requirements for flatness and moisture. The requirement for flatness is defined as the maxi-
mum difference between two adjacent high points and the intermediate low point. The
maximum acceptable difference in level is 3/16 of an inch in a 10-ft. radius. Wood subfloors
must have a stable moisture content between 6 – 10%. Creaking subfloors must be repaired
before installation. If the subfloor sags, inspect the joists below for twists or weakness. If
the subfloor is cupped or uneven at the joints, recheck the moisture content of the subfloor
to be sure it is in the 6 – 10% range. Check for excessive moisture in the crawl space or
basement and look for other signs of a potential water problem. High areas should be sand-
ed or planed, low areas patched or filled with an appropriate leveling compound, or covered
with a rigid underlayment. When using a leveling compound, be sure to follow the manu-
facturer’s recommendations, and allow the compound to dry completely before starting to
install the floor.
3) Chalk lines of a square reference point, as walls may out of square.
4) Lay out boards according to the plan.
5) Secure boards with construction adhesive to the wooden subfloor. Be sure to use adequate
adhesive and follow the recommended pattern.
6) Start layout of all pieces by securing a corner to allow for proper alignment.
6) Use 6” lengths of tubing in the grooves, lapping 3” into each board to help align the
grooves of the boards.
7) A 1/16” width space shall be used between boards.
8) After gluing boards in place, drill and screw or cross staple Infloorboards to subfloor,
according to recommended pattern.
9) Once all boards are installed, clean out all grooves with a vacuum.
10) Snap tubing into groove and route to manifold per plan.
11) Follow specific extra recommendations for each floor covering, and refer to the complete
installation manual for further instructions on the installation of the Infloorboard™
system.
