before, during and after the installation at the job

site, the relative humidity should be 30-90%. The tem-

perature should be at least 65°F for product acclima-

tion and at least 65°F two days after installation.

c. Pergo must be installed as a ﬂoating ﬂoor and must

not be ﬁxed to the subﬂoor. A

⁄4" expansion space

must be provided around the perimeter of the room

and any ﬁxed objects such as pipes or columns. Door

jambs and casings must be undercut. The Pergo

ﬂooring must be placed at least a

⁄4" beneath the

undercut jambs and casings. A

⁄4" expansion space

must also be included beneath the undercut jambs

and casings. Areas greater than 66 feet in length

or width require a

⁄2" expansion space around the

perrimeter of the room and all ﬁxed objects.

Areas greater than 66 feet in length or width,

i.e. (one room; two or more rooms with adjoining

archways greater than 4 feet; large room with an

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.

d. Pergo can be installed above, on or below grade.

e. Pergo planks are installed over Pergo SilentStep

foam or equivalent foam underlayment

when the Pergo product that you are installing does

not have an attached underlayment foam. When

installing over concrete, an additional underlayment,

, a 6-mil. (.15mm) non-recycled

(100% virgin) resin polyethylene vapor barrier or an

equivalent non-recycled 6-mil. polyethylene vapor

barrier, is required for all Pergo products.

f. Use approved safety equipment to provide proper

protection based on each given task. Always be

careful when handling the planks as the cut edge of

the laminate can be sharp.

g. Important— Always inspect each plank to make sure

it is not damaged prior to installation.

6. JOB SITE EVALUATION — Exterior conditions and how

they can inﬂuence the interior of a home.

a. Building codes are established to provide a safe living

space. There are nationally recognized building

codes, such as BOCA—Building Ofﬁcials and Code

Administrators International, Inc., and ICBO —

International Conference of Building Code Ofﬁcials

as well as others. There are state and local building

codes that also provide the same service and interest

assuring a safe and consistently built living or working

space. There are speciﬁc building codes that are

designed to prevent excessive moisture from damag-

ing the building materials. There are also maintenance

practices that are required to prevent excessive mois-

ture from damaging the building materials.

b. Water drainage from adjoining properties, changes to

your home site or incorrect building procedures or

damage can allow excessive water or moisture to

penetrate basement walls, ﬂow beneath concrete

slabs and basement ﬂoors and into crawl spaces. High

water tables can necessitate the use of sump pumps

to pump water that is ﬂowing beneath a concrete

ﬂoor. Pergo ﬂooring should not be installed over any

ﬂoor with a sump pump or in a room with a ﬂoor drain.

MOISTURE TEST:

A moisture test is recommended on all concrete

subﬂoors and wood subﬂoors constructed over a

crawl space or basement. Maximum acceptable

moisture reading for wood subﬂoors is 14%. Maximum

acceptable moisture reading for concrete subﬂoors

is 4.5% or a moisture vapor emission rate of

5lbs/1000sq. ft/24 hrs.

IMPORTANT NOTE: During a dry season, you may ﬁnd that

you get an acceptable moisture reading even if other

job site conditions are not acceptable. Before installing

Pergo ﬂoors, you must be sure that your job site condi-

tions as well as your moisture readings are acceptable.

c. For concrete subﬂoors, vapor barriers, such as the

recommended Pergo 6-mil. polyethylene ﬁlm

installed correctly, 8-inch overlap at seams, installed

up to the edge of the wall base or wall, will protect

the ﬁnished ﬂoor from normal water vapor that is

emitted through the concrete from a correctly con-

structed, maintained and undamaged building and

correctly graded site that prevents excessive water

exposure.

d. For wood subﬂoors, a vapor barrier is not placed on

the surface of the wood subﬂoor under any circum-

stance. When there is a basement, the basement

ﬂoor and walls must be dry. When there is a crawl

space the soil in the crawl space must be covered

by a 6 mil (.15mm) non-recycled (100% virgin) resin

polyethylene ﬁlm with seams overlapping at least 8

inches or more. Cover the surface of concrete in

crawl spaces with a vapor barrier. Vents should be

located throughout the foundation. They must pro-

vide good cross ventilation and no dead air space.

There must be minimum vent openings equal to 1.5%

of the square footage within the crawl space.

/2 sq. ft. of vent opening for every 100 sq. ft. of ﬂoor space with good cross ventilation.

Soil should slope away

for at least 10 feet.

Lawn sprinklers must

toward the foundation.
