TRADITIONAL HARDWOOD INSTALLED
DIRECTLY OVER INFLOORBOARD™
A conventional nailed and hard-
wood type system may be used
directly over Infloorboard™, with
nailing long enough to penetrate the
subfloor, and with the utilization of
recommended controls. See also sec-
tions on general considerations with
the use of traditional wood flooring.
Infloorboard™ shall be installed
over a wooden subfloor, complying
with “General Infloorboard™
Installation Requirements For All
Flooring Over Wood Subfloor”. In
addition, the following specific cautions and instructions shall be followed:
1) Care shall be taken to avoid nailing tubing.
2) Hardwood floor joints shall not be installed directly at the Infloorboard™
joint.
3) Hardwood floor nails shall be long enough to penetrate both hardwood and
subfloor.
4) Hardwood floors installed directly over Infloorboard™ shall employ controls
with a reset curve, that gradually adjust water temperature going to the
Infloorboard™; the floor will expand and contract gradually with temperature
changes. This will reduce the likelyhood of warpage, gapping or shrinkage
problems. The use of a floor temperature limiting sensor is recommended.
5) It is extremely important that the designer know which way it is desired that
the strip flooring be aligned prior to the design of the Infloorboard™ system,
since the direction of the Infloorboard™ should run perpendicular to the direc-
tion of the strip flooring.
6) Install strip flooring with mallet driven nails and nails penetrating the
Infloorboard™ 1/2” into the subfloor. Use 15 gauge nails (2.5” with 3/4”
floors) to penetrate the subfloor. A nailer such as the Senco # SFM40, with a
tongue and groove attachment such as # SFM40 TG, should be used.
7) Structure humidity shall be kept within the range specified by the flooring
manufacturer.
8) The wood flooring shall be installed at the relative humidity recommended by
the manufacturer for the climate involved.
9) Use narrower 2”-3 1/2” strips of wood flooring over radiant floors.
10) The lessons of local practice and climate shall be referenced
11) Make sure the heating system has been running and the space has been
maintained at least 65F° long enough that temperature and humidity have stabi-
lized to predicted future levels.
12) The flooring product shall be allowed to acclimatize before installation.
13) Use woods known to be dimensionally stable.
