PRODUCT USE
The ICR-225 thermally improved ribbon window system is intended for installation by glazing professionals
with appropriate experience. Subcontractors without experience should employ a qualified person to provide
field instruction and project management.
Oldcastle BuildingEnvelope ™ does not control the application or selection of its product configurations,
sealant or glazing material and assumes no responsibility thereof. It is the responsibility of the owner, architect
and installer to make these selections in strict compliance with applicable laws and building codes.
Consult sealant manufacturer for review and recommendation of sealant application. Follow sealant
manufacturer’s recommendations and literature for proper installation.
The air and water performance of the ICR-225 ribbon window system is directly related to the completeness
and integrity of the installation process. To insure top performance for this system, particular attention should
be given the following procedures.
PROTECTION AND STORAGE
Handle all material carefully. Do not drop from the truck. Stack with adequate separation so the material
will not rub together. Store material off the ground, protecting against the elements and other construction
hazards by using a well ventilated covering. Remove material from package if wet or located in a damp area.
For further guidelines consult AAMA publication “Care and Handle of Architectural Aluminum From Shop to
Site.”
2. The glazing gaskets should be installed so as to avoid stretching, buckles or tears. Corners must be
cut to tightly butt together and seal as described in these instructions. Avoid damage to gasket and
corner joints during glazing.
1. Surfaces to be sealed should be cleaned with isopropyl alcohol or solvent and dried as recommended
by sealant manufacturer to remove all dirt and cutting oils. Sealant at shear blocks should be a
minimum 3/16” diameter nominal, placed completely around the top, face and bottom of the shear
block without gaps in the sealant. Exposed surfaces should be cleaned after installing the horizontal.
Inspect joint for complete sealant contact, especially where the horizontal meets the face of the
vertical member. Repair joint as required.
Variations on the details shown are inevitable and are not the responsibility of Oldcastle BuildingEnvelope ™
when drawn by others. Oldcastle BuildingEnvelope ™ strongly encourages its customers to use its
Engineering department for calculations and shop drawings.
For Structural Silicone Glazing applications, the stress on the silicone should not exceed 20 PSI. Consult
sealant manufacturer for specific application to ensure proper loading on silicone joint.
Consult glass manufacturer for correct setting block location and length for glass sizes in excess of 40 sq. ft.
