Installation Guide

b. Dishwashers: When installing Pergo flooring in the
dishwasher space beneath cabinets, sealant MUST
be used in the perimeter expansion spaces where
the dishwasher is sitting. When flooring abuts the
dishwasher, place a full bead of sealant beginning
at the top edge of the floor down to the subfloor in
front of the dishwasher.
c. Refrigerators: When installing Pergo flooring in the
refrigerator space, sealant MUST be used in the
perimeter expansion spaces where the refrigerator is
sitting. Be sure to place sealant around openings for
water supply lines to the icemaker of the refrigerator.
NOTE: For built-in refrigerators, follow instructions for
sealing as for dishwashers.
d. Exterior doors: The expansion space in front of any
exterior door MUST be filled with sealant.
e. Use Pergo SilentStep
TM
or Pergo Soundbloc
TM
or an
equivalent as the foam underlayment for Pergo
products without an attached underlayment. Use the
Pergo Moisturbloc
TM
or equivalent 6-mil. (.15mm) non-
recycled (100% virgin) resin polyethylene film as a
vapor barrier when installing over a concrete subfloor.
f. Pergo must not be installed in rooms with a floor drain.
g. Pergo must not be installed over any floor that has a
sump pump—i.e. should there be a kitchen at a
below grade level or on-grade concrete slab in the
home and a sump pump is located in that below-
grade level subfloor or in the on-grade level subfloor,
then Pergo flooring cannot be installed anywhere on
that floor.
All reference to sealant means Pergo sealant or a 100%
mildew-resistant silicone sealant.
14. LAUNDRY ROOM INSTALLATIONS — All expansion
spaces in a laundry room MUST be filled with sealant.
a. Pergo must not be installed in rooms with a floor drain.
b. Pergo must not be installed over any floor that has a
sump pump— i.e. should there be a laundry room at
a below grade level or on-grade concrete slab in
the home and a sump pump is located in that
below-grade level subfloor or in the on-grade level
subfloor, then Pergo flooring cannot be installed
anywhere on that floor.
c. The expansion space around the perimeter of the
Pergo floor must be
3
⁄8" wide and sealed prior to
installing the wall trim. The
3
⁄8" expansion space must
be completely filled with sealant to avoid water
getting underneath the floor.
d. The expansion space in front of any exterior door
MUST be filled with sealant.
e. Use Pergo SilentStep
TM
or Pergo Soundbloc
TM
or an
equivalent as the foam underlayment for Pergo
products without an attached underlayment. Use
the Pergo Moisturbloc
TM
or equivalent 6-mil. (.15mm)
non-recycled (100% virgin) resin polyethylene film as
a vapor barrier when installing over a concrete subfloor.
f. When Pergo flooring is installed in a laundry room
and an adjoining hall or room, a T-Molding must be
installed in the doorway between the rooms or hall-
way and the expansion space under the T-Molding
must be filled with the proper sealant. Place sealant
in the expansion space of any flooring transition in
the doorway of a laundry room.
15. RADIANT FLOOR HEATING —Pergo flooring can be
used in combination with many types of in-floor heating.
The heating system can be cast in a concrete floor
or in a thin layer of filler on the surface of a concrete
subfloor. It can also be installed under a wood sub
floor or installed on the surface of the subfloor as an
electrical matting as long as it meets the floor flatness
requirements.
a. Follow the instructions from the supplier of the floor
heating system.
b. Concrete subfloors must be installed and cured with
no heat transfer for a minimum of 60 days.
c. The heating system must be in operation for at least
two weeks before installation. The system may be
turned off or set to a suitable installation temperature
(65 to 72°F).
d. The flooring surface temperature, that is the surface
of the subfloor or the heat radiating from electric
heating mats, should not exceed 84°F (29°C).
16. COTTAGES AND ROOMS WITHOUT CLIMATE
CONTROL —Pergo can be installed in homes or rooms
without climate control with the following conditions:
a. Pergo installation essentials must be met.
b. The crawl spaces must be enclosed and vented and
meet all requirements, and the job site conditions must
be correct.
c. Insulation of the floor in the crawl space is recommended.
d. The floor must not be installed in an area where it will
be exposed to constant dampness or extremely high
or low humidity. Relative humidity must range
between 35-60%. The temperature should be at least
65°F for the product acclimation and at least 65°F
two days after the installation.
17. COMMERCIAL APPLICATIONS — (Only for those
products that are designated for commercial use
by Pergo, LLC.)
In commercial applications, an expansion space of
1
⁄2" is
required at all walls, pillars, pipes and other fixed objects.
Areas greater than 40 feet in length or width, and
consecutive multiples of 40 feet, i.e. (one room; two or
more rooms with adjoining archways greater than 4 feet;
large room with extended hallway) must have a T-Molding
installed across the width of the room, archway or at
the beginning of the hallway to provide additional
expansion space.
When fastening fixtures to a floating floor, the anchoring
bolts or fasteners must have the same expansion space
