PART 3 EXECUTION

3.1 EXAMINATION

  1. Do not begin installation until substrates have been properly prepared.
  2. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
  1. PREPARATION
  2. Clean surfaces thoroughly prior to installation.
  3. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
  4. INSTALLATION
  5. Install fasteners in accordance with manufacturer's instructions.
  6. Install fasteners using manufacturer's approved fastening patterns at the appropriate fastening rate as determined in the most current revision of ASCE-7 or the Factory Mutual Approval Guide.
  7. Plate installation:
  8. Locate plates in the appropriate grid pattern in accordance with the membrane manufacturer's instructions.
  9. Install plates in straight rows to the specified number per 4-foot by 8-foot insulation board to achieve the required wind uplift resistance in the main field, edges and corners of the roof.
  10. Install plates using fasteners that comply with the specified Factory Mutual wind uplift rating and the fastener and membrane manufacturer's requirements. Ensure that all fasteners are properly driven normal to the surface of the sub-structure. Do not over-drive fasteners; plates that are recessed into and/or not flush with the surface of the insulation are not acceptable.
  11. Induction welding tool, use and operation:
  12. Use only the isoweld® 3000 induction welding tool and accessories by SFS intec with isoweld® Plates and Dekfast fasteners. These 3 components are uniquely designed as a system and must not be separated. Using alternative welding devices, plates and/or fasteners voids all test data and warranties.
  13. The induction welding tool must be designed with the following features, alternative systems not meeting these criteria are not permitted:
  14. Allow operation in stand-up mode or hand held inductor mode
  15. Adjustable handle and wheels for easy mobility on roof
  16. Automatically adjust search, find and energy levels for changes to ambient temperature.
  17. Internal settings to adjust for membrane types, single thicknesses and double thicknesses (x2 function when 2 layers of membrane are present).
  18. 1-step calibration
  19. Built-in plate finding security
  20. Automatically adjusts to power spikes
  21. 3-way weld verification: visual, audible and LCD counter
  22. Prior to commencement of work, select the proper membrane type and thickness and calibrate the isoweld® 3000 in accordance with the manufacturer's instructions. Provided the tool is not powered off, no further adjustments are necessary. Once the tool is powered off, it must be set and calibrated in accordance with the manufacturer's instructions. Systems using induction welding tools that allow false-positive welds and/or require manual adjustments to energy levels and/or require re-calibration for changes to ambient air temperatures are not permitted.
  23. Prior to commencement of work, perform test weld in accordance with the manufacturer's instructions and ensure all prescribed criteria are met prior to starting project.
  24. Immediately after welding, place the manufacturer's magnet assembly over the welded plate and leave in place for at least 1-minute to apply the necessary clamping pressure and cool the welded plate. Not using or improper use of magnets will void all test data and warranties.
  25. Contractor shall be trained by the manufacturer's technical representative in the proper use and operation of the isoweld® system.
  26. Power:
  27. Dedicated, 5000 Watt generator.
  28. 100-foot long maximum, 12-gauge minimum extension cord.
  29. Use the isoweld® 3000 hand-held induction welder for vertical surfaces and hard to reach areas around and under roof mounted units. Systems that do not have devices for welding vertical surfaces and hard to reach areas around and under roof mounted units are not permitted.
  30. Special considerations for EPS, XPS and foil faced insulation materials:
  31. EPS and XPS insulation - To prevent melting hazard, use the Isoweld® separator pad between the isoweld® plate and top surface of the insulation. Systems that do not have a manufactured solution to this hazard are not permitted. Contractor and/or shop fabricated solutions are not permitted.
  32. Foil faced insulation - The isoweld® 3000 tool automatically corrects its search and find and energy levels when foil faced insulation is utilized. Systems that do not have internal features to compensate for foil faced insulation are not permitted.
  33. Cleaning: Tools and accessories shall be operated and maintained in accordance with the manufacturer's instructions. Inspect induction welding head for dirt, use replacement pads when necessary. Inspect magnet heads for dirt and debris, clean as necessary to prevent dirt and debris from being pressed into the membrane during clamping and cooling cycles.
  34. PROTECTION
  35. Protect installed products until completion of project.
  36. Touch-up, repair or replace damaged products before Substantial Completion.
