APPLICATION OF INFLOORBOARD™ OVER CONCRETE, WITH STRIP WOOD FLOORING
INSTALLATION OVER CONCRETE:
Installing parties must accept responsibility for and understand all cautions on page 30
regarding moisture and attachment of Infloorboard™ to concrete, and should refer to the
complete installation manual for further instructions on the installation of the
Infloorboard™ system. Do not install Infloorboard™ without an accurate room-by-room
heat loss for the structure to be heated, as well as a design/layout for Infloorboard™ that
takes into account the resistance and heat transfer of the actual floor coverings. If
Infloorboard™ cannot provide all the necessary heat, make provisions for additional backup
heat.
1) Thoroughly clean and level all surfaces that Infloorboard™ will be applied to.
2) Seal concrete with a vapor membrane such as Hydroment Ultraseal per manufacturers
guidelines.
3) Glue T&G 3/4” plywood down to vapor membrane. Be sure to use adequate adhesive
compatible with vapor membrane to glue down the plywood to the membrane. Weight the
plywood if necessary to make it lie flat
4) Chalk lines of a square reference point, as construction of walls may be inconsistent.
5) Lay out boards according to plan.
6) Glue and screw or staple Infloorboard™ to plywood. Be sure to use adequate adhesive.
7) Start layout of all pieces by securing a corner, to allow for proper alignment.
8) Use 6” lengths of tubing in the grooves lapping 3” into each board to help align the
grooves of the boards.
9) Once all boards are installed, clean out all grooves with a vacuum just prior to tubing
installation.
10) Snap tubing into groove and route to manifold per plan.
11) Install strip flooring with mallet driven nails and nails penetrating the Infloorboard™
1/2” into the plywood. Use 15 gauge nails (2.5” with 3/4” floors) to penetrate into ply-
wood. A nailer such as the Senco # SFM40 with a tongue and groove attachment # SFM40
TG should be used.
12) Insulfoam/plywood combination may be used instead of plywood alone in strip floor-
ing provided the plywood layer is at least 5/8” thick (3/4” preferred) and the foam can be
successfully bonded with a compatible adhesive to the vapor membrane. The plywood is
placed on the foam and ramset to the slab.
13) Hardwood floors installed directly over Infloorboard™ shall employ controls that grad-
ually adjust water temperature going to the Infloorboard™ with a reset curve.
