INSTALLATION INSTRUCTIONS - INSTRUCCIONES DE INSTALACION
ADVANCED PERFORMANCE AND HURRICANESHIELD® IMPACT RESISTANT
CLAD FRAME AND CIRCLE HEAD WINDOWS IN WOOD FRAME CONSTRUCTION
These instructions were tested and are Dade County certified for single laminated glass and
ASTM (Hallmark) certified for laminated insulating glass.
Important Safety Information:
Pella® HurricaneShield® products have been tested in accordance with the large missile impact
testing requirements of ASTM E 1886 and ASTM E 1996. Pella HurricaneShield products are
neither hurricane proof nor are they shatter proof. Severe wind and rain may produce temporary
conditions which exceed product performance standards. When these units are subjected to
intense storms or extreme conditions, which exceed the intended design pressures, air, water and
flying debris infiltration may occur. The performance of any building is dependent upon the
design, installation, and workmanship of the entire building system. Pella Corporation strongly
recommends consulting an experienced architect, contractor, or structural engineer prior to
installation of Pella products.
The individual (building owner, architect, contractor, installer and/or consumer) responsible
for the project must take into account local conditions, building codes, inherent component
limitations, the effects of aging and weathering on building components, and other design issues
relevant to each project. The determination of the suitability of all building components for each
project, as well as the design and installation of flashing and sealing systems, are the responsibility
of the building owner, architect, contractor, installer and/or consumer.

TWO OR MORE PEOPLE WILL BE REQUIRED FOR THE FOLLOWING STEPS.
A. Insert the window from the exterior of the building.
Place the bottom of the window on the spacers at
the bottom of the opening, then tilt the top into
position. Center the window between the sides of the
opening to allow clearance for shimming, and insert
one roofing nail in the first hole from the top of each
jamb nailing fin. These are used to hold the window
ꢂ"
in place while shimming it plumb and square.
B. Plumb and square window. Place shims between
the window frame and the rough opening at each
installation screw hole. Adjust the shims as required
to plumb and square the window in the opening.
ꢂ#
Note: DO NOT over shim.

C. Check the interior reveal. Make sure the
measurement from the interior face of the window to
the interior face of the wall is equal at several points
around the window.

A. Units that do not have pre-applied fin
corners: Cut four pieces of flashing tape
ꢂꢊꢂꢀꢃꢅ LONGꢇ !PPLY ONE PIECE OF mASHING
tape to each end of the sill fin so that it

Note: The flashing tape must be applied approximately 1/2"
onto the frame cladding at the jambs and head. Pre-folding the
tape at 1/2" before removing the paper backing will make it
easier to apply the tape correctly. If the siding is less than 1/2"
thick, adjust the dimension of the fold so the exterior sealant
line will cover the exterior edge of the tape.
B. Apply side flashing tape. #UT TWO PIECES OF mASHING TAPE ꢋꢅ LONGER

Note: DO NOT tape or seal the bottom nailing fin.
ꢄ#
C. Circle top window:
Apply top flashing tape. First layer: Several pieces of flashing tape will be needed
to cover the top fin. Start taping from the sides of the window working toward the
peak. To determine the length of cuts, hold the tape along the radius, and cut the
tape just past where it leaves the top fixed extruded fin or for the flexible fin, just
PAST THE mEXIBLE WEATHERꢊ
strip. The top tape must
overlap the one beneath
it in order to divert water
properly. The sharper the
arc of the window, the
shorter the pieces of tape
will be.

before attempting to drive the screws in.
INTERIOR SEAL

Caution: Ensure use of low pressure polyurethane window and door insulating foams
and strictly follow the foam manufacturer’s recommendations for application. Use of high
pressure foams or improper application of the foam may cause the window frame to bow
and hinder operation.

When applying siding, brick veneer or other exterior finish material, leave adequate space
between the window frame and the material for sealant. Refer to the illustration that
corresponds to your finish material.
Note: The sealant details shown are standard recommendations from the sealant industry.
Contact your sealant supplier for recommendations and instructions for these and any
other applications.

A. Insert backer rod into the space around the window to provide approximately
ꢂꢀꢆꢅ CLEARANCE BETWEEN THE BACKER ROD AND THE EXTERIOR FACE OF THE WINDOWꢇ
Note: Backer rod adds shape and depth for the
sealant line.
B. Apply a bead of high quality exterior grade sealant to
ꢇ"
the entire perimeter of the window.
Note: For wood siding applications, when using the
flexible fin, ensure the sealant bead covers the exterior
edge of the fin weather-strip.
C. Shape, tool and clean excess sealant. When finished,
the sealant should be the shape of an hourglass.
Note: This method creates a more flexible sealant
line capable of expanding and contracting.

IMPORTANT NOTICE
Because all construction must anticipate some water infiltration, it is important that the wall system be
designed and constructed to properly manage moisture. Pella Corporation is not responsible for claims
or damages caused by anticipated and unanticipated water infiltration; deficiencies in building design,
construction and maintenance; failure to install Pella® products in accordance with Pella installation
instructions; or the use of Pella products in wall systems which do not allow for proper management
of moisture within the wall systems. The determination of the suitability of all building components,
including the use of Pella products, as well as the design and installation of flashing and sealing systems
are the responsibility of the Buyer or User, the architect, contractor, installer, or other construction
professional and are not the responsibility of Pella.
Pella products should not be used in barrier wall systems which do not allow for proper management of
moisture within the wall systems, such as barrier Exterior Insulation and Finish Systems (EIFS)
