| Description:
Basic
Use:
Fiberweb 200 is an inert, lightweight, flexible, reinforced
polyester membrane thru-wall flashing. It is impervious
to moisture penetration; not affected by caustic alkalis
found in concrete and mortar mixes, is easily installed
and has guaranteed longevity of 75 years.
Limitations:
Fiberweb 200 cannot/should not be used as an exposed
flashing.
Composition
and Materials:
Fiberweb 200 is a combination of black polyester film
reinforced with fiberglass scrim and vinyl film; average
finished thickness is 8 mils.
The adhesive used in the lamination process is virtually
indestructible resulting in extra high resistance to
delamination.
Sizes:
Fiberweb 200 is available in widths of 12", 16",
18", 20", 24", 36", and 48".
Custom sizes over 48" are available With a 4-6
week lead time. Standard length is 300 lineal feet per
roll.
Tape:
Fiberweb Tape is the same polyester film as in the flashing;
.
When used to repair a puncture will restore the integrity
of the flashing to its physical properties 2" x
108 lineal feet per roll
Applicable
Standards:
Fiberweb 200 conforms to the requirements of the following
specifications:
Army Corps of EngineersCEGS-07600
Navy Corps of Engineers
MIL-I-631D
MIL-Y-1140H
MIL-P-1459IC (MR)
HH-C-466b
Technical
Data:
"Mylar" polyester film is made from polyethylene
terephthalate, the polymer formed by the condensation
reaction of ethylene glycol and terephthalic acid. Its
unusual balance of properties enables it to serve specific
engineering functions as aphysical barrier in protective
coatings, as a thermal barrier, as a structural barrier
and as an electrical barrier.
"Mylar" contains no plasticizers and does
not become brittle with age at its normal operating
conditions

Corrosion
Resistance:
Freshly prepared freshly prepared specimens were prepared
employing a mixture of portland cement, sand, water
aggregate and admixtures. a strip of Fiberweb sheeting
was placed between freshly prepared specimens and already
existing, plain and air entrained concrete slabs. This
combination remained at ambient temperature for a period
of 14 days and 28 days and then evaluated for adverse
effects.
Results:
No changes in 14 days
No changes in 28 days
