This system from Fortifiber Building
Systems Group raises the standard for
flashing windows and doors. The system
starts with your choice of one of two tried
®
and true Fortifiber products, Moistop PF
®
or Moistop neXT . This base layer of
flashing is mechanically attached (largeheaded nails).
Once the rough opening is prepared, proceed
by attaching Moistop PF Flashing (A) flush
along the bottom of the rough opening. Be sure
not to fasten the lower edge of the flashing so
that a Fortifiber weather-resistive barrier may be
slipped up underneath the flashing in a weatherboard fashion, extend the flashing beyond the
jamb flashing to be applied later.
Cut a strip of Moistop PF Flashing long enough to extend beyond
sill flashing already in place, and above where the Moistop E-Z
Seal head flashing will intersect. Next attach the jamb flashing (B)
flush to the edge of the rough opening leaving the bottom free.
Repeat above steps for the remaining jamb.
Caulk flange
with
bead.
Before installing the window (C), Apply a continuous
bead of
Moistop Sealant to the perimeter of the rough opening or to the
backside of the mounting flange (D) of the window. Install the
window according to the window manufacturer’s instructions.
Wipe the window flange (D) and base Moistop PF Flashing (B)
layer clean before applying Moistop E-Z Seal. Cut the desired
length of Moistop E-Z Seal with a sharp knife. Pull off the release
paper and place the Moistop E-Z Seal on top of the window
flange. Apply firm pressure along the entire self adhesive strip to
ensure a continuous seal.
Once the High Performance
Window Flashing System is
properly installed, apply a
Fortifiber weather-resistive
barrier in a weather-board
fashion.
Limitations: For optimum adhesion, Moistop E-Z Seal and FortiFlash flashing should
be applied at temperatures between 40° F (4.4° C) and 120° F (48.9° C). FortiFlash is
the only Fortifiber flashing product that can be installed horizontally or at a slope of less
than 60°. Product should be covered as soon as possible. Inspect product to insure it is
free of any protrusions or damage which may compromise its moisture-resistive
properties. FortiFlash is not compatible with EPDM or flexible (plasticized)
Polyvinyl Chloride (PVC) based products. FortiFlash also is not compatible with
some sealants. Consult with sealant manufacturer for compatibility information.
Direct exposure of sealant to the adhesive side of FortiFlash can be detrimental if the
amount of sealant exceeds what is specified above. Please follow these recommendations regarding location and amount of sealant to be used. Fortifiber strongly
recommends against the practice of using a knockdown bead of sealant, or buttering
the flange with sealant, because this amount of sealant is excessive and unnecessary.

Este sistema de Fortifiber Building Systems
Group eleva la norma para el escurrimiento
de ventanas y puertas. El sistema comienza con
su elección entre uno de dos productos
Fortifiber comprobados de calidad, Moistop
®
®
PF o Moistop neXT , esta capa base de
plancha de escurrimiento se coloca
mecánicamente (con clavos de cabeza grande).
Una vez que la apertura basta está lista, proceda a
acoplar la Plancha de Escurrimiento Moistop PF (A)
al ras de lo largo de la parte inferior de la apertura
basta. Asegúrese de no fijar el borde inferior de la
plancha de manera que una barrera resistente a la
intemperie de Fortifiber pueda deslizarse por debajo
de la plancha a modo de capas solapadas; extienda
la plancha más allá del escurrimiento por montante
que será aplicado más adelante.
Corte una tira de Plancha de Escurrimiento Moistop PF lo
suficientemente larga para extenderse más allá del escurrimiento de
antepecho ya en su lugar, y por encima de donde el escurrimiento por
frente Moistop E-Z Seal hará la intersección, acople la tira (B) al ras del
borde de la apertura basta dejando libre la parte inferior. Repita los pasos
anteriores para la instalación del resto del montante.
Limpie el reborde de la ventana (D) y la capa base de escurrimiento
Moistop PF (B) antes de aplicar Moistop E-Z Seal. Corte el largo
deseado do Moistop E-Z Seal con un cuchillo afilado. Tire del papel que
lo cubre y sitúe el Moistop E-Z Seal arriba del reborde de la ventana.
Aplique presión firme a lo largo de toda la tire de tela autoadhesiva para
asegurar que se selle de manera continua.
Una vez que el Sistema de Escurrimiento
para Ventana de Alto Rendimiento ha
sido instalado apropiadamente, aplique
una barrera resistente a la intemperie de
Fortifiber a modo de capas solapadas.
