	** NOTE TO SPECIFIER ** Henkel Corporation; window installation system products. This section is based on the products of Henkel Corporation, which is located at: 26235 First St. Westlake, OH 44145 Toll Free Tel: 800-624-7767 Tel: 440-250-7700 Email: request info Web: www.osipro.com/greenseries [ Click Here ] for additional information. OSI® products are developed and marketed by Henkel Corporation's Professional Adhesives group. Henkel Corporation is part of Henkel, a worldwide leader in adhesives and a European leader in laundry/home care and personal care products. OSI® WINTeQ™ window installation system is part of Henkel's OSI® product line. The OSI® brand is an authority in providing professional-grade caulks, sealants and adhesives. With a breadth of color-matching caulks for the siding industry, OSI® helps contractors make their work easier, always offering professional results. The new OSI® WINTeQ™ system has simplified the process of selecting compatible, reliable products, making the window installation process as easy as three simple steps: Flash, Seal, Foam. Not all installers currently execute all three steps in window installation. But, with the compatibility and performance of the OSI® WINTeQ™ system, these three simple steps lead to proper window installation, with a decreased risk of water and moisture penetration and increased energy efficiency and performance. This specification includes WINTeQ TeQ::Flash™ flexible flashing that has been developed specifically for the WINTeQ Window Installation System. It is efficient, easy to use and provides excellent moisture and air infiltration protection around windows. It can also be used to seal doors and smaller gaps and openings. TeQ::Flash can be easily applied in horizontal and vertical applications and will adhere to most common building substrates including vinyl, wood and concrete.

	PART 3	EXECUTION
	3.1	EXAMINATION
		A.	Do not begin installation until substrates have been properly prepared.
		B.	Verify substrate surfaces are ready to receive work.
		C.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
	3.2	PREPARATION
		A.	Clean surfaces thoroughly prior to installation.
		B.	Coordinate installation of flashing system with installation of doors and windows and adjacent finish materials to ensure material is provided in timely manner.
		C.	Prime concrete, masonry and exterior gypsum substrates as required.
		D.	Do not apply primer or flashing to damp, frosty or contaminated surfaces.
		E.	Do not use in areas where flashing will be subject to continuous exposure to sunlight or to temperatures in excess of 180 degrees F (82 degrees C).
		F.	Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
	3.3	INSTALLATION
		A.	Install in accordance with manufacturer's instructions.
		B.	Prepare rough openings by cutting back weather resistant barrier. Create an upper flap to allow clearance for head flashing. Flip head flap up, exposing sheathing and temporarily secure.
		C.	Cut flexible flashing using the following flashing cut formulas:
			1.	Sill Flashing = rough opening width plus (2 X flashing width).
			2.	Jamb Flashing = Rough opening height plus (2 X flashing width) minus 1 inch (25 mm).
			3.	Head Flashing = Rough opening width plus (2 X flashing width) plus 2 inches (51 mm).
		D.	Apply the horizontal sill flashing level with the top edge of the rough opening frame. Each end of the sill flashing should extend approximately 9 inches (229 mm) beyond the rough opening at the jamb.
		E.	Apply a continuous bead of elastomeric flange sealant to the back side of the window flange on the interior surface. Sealant should be applied in line with the nail slots on the mounting flange when provided. Or the sealant may be applied to the framed opening directly to the vapor barrier where the back side of the mounting flange will make contact with the perimeter seal. Never leave holes uncovered.
		F.	Immediately set the window into the opening and install in accordance with window manufacturer's instructions.
		G.	Apply jamb flexible flashing on the left and right sides of the window flange. The jamb flashing should extend approximately 8.5 inches (216 mm) beyond the head and sill of the rough opening.
		H.	Apply head flashing over the top nail flange on the window. Head flashing should extend beyond the jamb flashing by 1 inch (25 mm) on each side.
		I.	Pull down upper flap of weather barrier so it lays flat across head flashing. Tape along all cuts in weather barrier and across head with manufacturer approved weather barrier tape.
		J.	Install flexible flashing tape around other gaps and openings in exterior wall assemblies as required.
		K.	Fit flashings tight in place. Make corners square, surfaces true and straight in planes, and lines accurate to profiles.
		L.	Install polyurethane foam on the interior side of the window, filling the gap between the window and the frame.
		M.	Apply materials within recommended application temperature ranges. Consult manufacturer when materials cannot be applied within these temperature ranges.
	3.4	CLEANING
		A.	Clean adjacent soiled surfaces.
	3.5	PROTECTION
		A.	Protect installed products until completion of project.
