Interior Components Exterior Expansion Joint 651 Series Horizontal Joint

The 651 system is capable of multi-directional movement between adjacent buildings.

The following information has been provided by Interior Components Exterior Expansion Joint demonstrating how this product complies with the Building Product Information Requirements.

Product Description

The 651 exterior roof expansion joint system is capable of multi-directional seismic movement and is particularly suitable where existing joint openings are irregular or where variations in structural joint width need to be accommodated with its surface-mounted design.

The system is designed to accommodate substantial thermal, structural and seismic movement between adjacent building elements while providing a weather-resistant cover over the structural expansion joint.

The 651 Series incorporates exterior-grade metal cover components together with a waterproofing/moisture-barrier arrangement appropriate to the selected configuration.

Application: Exterior

Joint Size: 25mm - 406mm

Movement: Seismic - Greater than or equal to 50% (+/-)

Install: Roof to Roof / Roof to Wall

Compliance Statement

Product Class

Scope of Use

The 651 system must be used within the limitations specified by Inpro for the particular product configuration.

The nominal structural joint width must be confirmed against the approved construction documentation and Inpro product data before manufacture or installation.
The surrounding substrate must be structurally adequate to support the expansion joint system and its fixings.
The system must be installed onto a level and suitable substrate in accordance with Inpro's installation requirements.
The 651 architectural joint cover does not determine the required structural seismic gap.
Structural joint width and movement requirements remain the responsibility of the project structural designer.
The required movement range must be established by the project structural engineer or other suitably qualified project designer.

New Zealand Building Code (NZBC)

The product will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:

Notes

B1 Structure: The 6501 Series is designed to accommodate structural expansion-joint movement resulting from conditions including Earthquake movement, Thermal expansion and contraction, Wind-induced building movement, Lateral/shear movement.

B2 Durability: The 651 system incorporates materials designed for exterior use, including aluminium, stainless-steel fixings and weather-resistant composite exterior panels.The composite metal exterior panel incorporates an architectural-grade fluoropolymer coating meeting AAMA 2605 requirements. Periodic inspection and maintenance of waterproofing interfaces, sealants, cover assemblies is required to ensure continued performance.

E2 External Moisture: The 651 Exterior Horizontal Expansion Joint contributes to the external moisture management of the roof/building envelope by providing a weather-resistant expansion joint cover and accommodating compatible waterproofing membranes. JM651 is not, by itself, a complete roofing or cladding system.

Expected closing movement
Seismic movement
Shear movement where applicable
Roof-to-Roof or Roof-to-wall condition
Substrate construction
Adjacent Roof or wall finish
Exterior exposure conditions
Finish requirements
Moisture-barrier requirements
Transition details
Termination details
Fire-rating requirements, if any.

Product selection must be based on the latest Inpro technical data and approved project-specific shop drawings.Where actual site conditions differ from the approved details, Interior Components Limited must be notified before installation proceeds.

Installation requirements
