BENCHMARK

Welcome to Kingspan, global leaders in the design and manufacture of insulated metal panels and building envelope solutions. Insulated panels serve as energy efficient, state-of-the-art alternative to traditional construction.

This document serves as installation guidelines for the BENCHMARK By Kingspan Flushglaze 4500 window system.

DisclaimerThis installation guide is only to be used in conjunction with panel installation drawings and Kingspan recommended details. Details shown in project shop drawings take precedence over any similar information in this manual. Shop drawings may be prepared either by Kingspan or by the panel contractor. Kingspan Technical Service Department is available to assist the panel contractor in the review of shop drawings.This guide is intended to provide the panel contractor with recommended methods, procedures and guidelines for the installation of the Flushglaze 4500 window system for architectural applications. Information presented is accurate but may not cover all situations, building conditions and/or details of your specific project. Consult Kingspan Technical Services where this guide does not cover your unique construction requirements. It is the sole responsibility of the project engineer and panel installer to ensure specified air and weather tightness of a building by good design and workmanship in accordance with approved drawings using only the appropriate type of sealants. It is the sole responsibility of the owner’s representative and panel installer to maintain quality workmanship in accordance with approved shop drawings to ensure the best performance of the wall system. Kingspan recommends installers read this document fully before receiving the panels on the job site. Installation classes are available through Kingspan’s Technical Services Department. Please call 1-888-332-5862 for more information.Follow the architect’s approved shop drawings and engineering calculations for your project specific fastening patterns. The engineer of record is responsible for verifying applicable design loads and panel fastening requirements.All safety procedures, including adequate fall protection, are the responsibility of the panel contractor.

1. INTRODUCTION FLUSHGLAZE 4500

1.1 FEATURESFlushglaze 4500 satisfies an ever increasing need to integrate architectural window systems with horizontal panel joinery. The 4-1/2” or 6” deep storefront design system is ideal for continuous run fixed “strip” windows that are flush with the plane of the panels. Designed to preserve and maintain the same weather proofing principles as insulated metal panels.

Thermal breaks in all components

Positive water barrier and drainage

Concealed splice plates

Front set glass pocket

Snap-lock frame connectivity

Window systems are reglazable without dismantling of the insulated metal panel system or window frame

Integrates with Designwall™ 2000/4000, Designwall™ Shadowline and Designwall™ R Series

Operable vents available per specific application

2. INSPECTION UPON DELIVERY FLUSHGLAZE 4500

3.1Review shop drawings prior to installation to verify that structural members are in the correct location.

3.2Installer must examine the alignment of the structural steel before installation of the window system. The walls must be square, and support members to which extrusions are attached must be in the same plane, flat and free of obstructions such as weld marks, bolts or screw heads.

Flushglaze 4500 components are carefully packaged then shipped on flat bed trailers to the construction site. When a shipment is received, check all items against the shipping document for quantities, dimensions, colors, transit damage, etc. Document any shortage of materials or damage on the bill of lading and have it signed by the driver.

It is the receiver’s responsibility to make any damage claims immediately. Please note that although every effort is made to prevent shipping damage, Kingspan is not responsible for damage which may occur during transportation, delivery, storage or on-site handling.

3. STRUCTURAL ALIGNMENT FLUSHGLAZE 4500

Support members shall be:

a. Plus or minus 1/8” (3.17 mm) in 5 feet (1524 mm) in any direction along plane of framing.

b. Plus or minus 1/4” (6.35 mm) in 20 feet (6096 mm) cumulative in any direction along plane of framing.

c. Plus or minus 1/2” (12.7 mm) from framing plane on any elevation.

d. Plumb or level within 1/8” at all changes of wall direction for preformed corner panel applications. Any variance from tolerances can affect performance, aesthetics, and installation and must be reported to the general contractor, and corrected by the responsible party before panel installation begins.

e. Rough opening at jambs 1” larger than frame size. Head and sill rough opening set precisely per section 4.3.

4.3Install panels up to the bottom of the window.

Ensure that the bottom of the structure (at the window head) is set approximately 1/4” above the design location of the top of the window frame head adapter.

Ensure that the top of the structure (at window sill) is set 1” maximum above the design location of the bottom of the window frame sill adapter.

Field cut top of panel and set in continuous horizontal bead of non-skinning butyl tube sealant.

4.4Install window sill adapter extrusion (using appropriate hook anchor if identified) with #14 screws 16” on center; caulk over all fastener heads with silicone or urethane sealant to avoid leakage. Caulk under all hook anchors as well as over top of the fastener heads. Hook anchor is supplied in 17’-6 stock lengths, typically field cut to 6” long pieces, and installed 32” to 48” o.c. as needed.

Shim under sill adapter as needed.

If hook anchors are needed, refer to project details for spacing requirements.

4.5If the sill adapter extrusion must be spliced, use 3/8” wide urethane foam compression pads with peel off backing at all splices. Field compress the splice pad to 1/4” thickness.

A metal splice plate can be installed in the front recess of the sill extrusion if the color of the splice pad is unacceptable.A

4.6Install end dam at each end of window sill adapter extrusion using two #10 TEK screws or rivets.

Seal end dam to window sill adapter using sealant and also plug the ends of the drainage trough of the sill adapter with sealant.

Ensure that 1/4” weep holes 24” on center have been factory drilled in the drainage trough of the window sill adapter extrusion.

4.7Run a continuous bead of non-skinning butyl sealant along the inside of the backside of the sill receptor, which will be connected to the vertical bead of sealant.

Insert the Flushglaze window units directly onto the sill adapter extrusion, making sure it locks into place.

Shim as required at the window head.A

4.8Once the Flushglaze unit has been properly positioned, fasten down through the glazing pocket of the sill into the hook anchor with a #10-16 x 3/4” screws per job specific requirements.

Caulk over the fastener heads with silicone or urethane sealant to prevent leakage.A

4.9Upfasten the window head to the top structure with a minimum #12 x 2” screws 16” on center.

Ream out fastener hole in head extrusion slightly larger than fastener shank to allow structure above to deflect without straining the window frame.

Shim as required. Glass stop will need to be removed.

Do not drill through the glass stop.

4.10Install adjacent window unit, snapping it into the previous unit at the vertical joint.

Before snapping it into the unit, apply a 12” long bead of silicone or urethane sealant beginning at the base and extending upward at the snap lock mechanism.

Fasten and shim as before.

Repeat for adjacent window units until the far end of the window has been reached.

4.11An angular mending plate is required at the jamb of the windows. Caulk this mending plate to the vinyl filler of the window frame using non-skinning butyl tube sealant the full height of the jamb.

This sealant must be connected to the sealant bead along the sill at step #7 and also to the top sealant in the next step.A

4.12Seat the head adapter extrusion onto the top of the window frame; the window head extrusion is supplied with a factory applied V786 tape.

Head adapter extrusion is normally provided in 17’-6 stock lengths and must be cut to length and / or spliced as necessary.

If head adapter extrusion must be spliced, use a Z-shaped inside metal splice plate, bed sealed in butyl sealant; the V786 tape must be peeled back for half the length of a splice plate and re-adhered over the underside of the splice plate.

Connect the V786 tape to the vertical sealant at the jambs.

Extend the V786 tape to the back of the adapter extrusion at the ends to seal off the ends (additional roll will be furnished for this purpose).

At the window jamb / ends, cut back the ISO foam blocking and plug the ends of the drainage cavity with silicone sealant to force excess water to exit at weep holes.
