Tech Summary

Thermal Transmission Properties

R-value measures resistance to heat flow. The American Society of Testing and Materials (ASTM) C 518-04, (Standard test method for steady-state thermal transmission properties by means of the heat flow meter) provides a rapid means of determining the steady-state thermal transmission properties of thermal insulations and other materials with a high level of accuracy. Available in thermal R-values of R-19, R-25 & R-30.

Joint Opening Size Confirmation

SIZES: Standard Widths are 1-to-20-inch nominal and Custom Seismic Widths are available.
Prior to installation always confirm that system sizes supplied will accommodate both the minimum and maximum joint width. Refer to MM Systems product drawings and project specific contract drawings. Too often expansion joint openings are sized without adjustment resulting in larger than anticipated openings. Not knowing the actual expected minimum and maximum joint opening may result in product failure or costly replacement orders if not properly sized.

Installation

  1. IVB is supplied in 5-foot segments. Determine the quantity required for each joint run.
  2. Adjoin segments together by inserting male flush ends into female splice pockets ends.
  3. Remove splice tape release liner from seam strips on male end and cover with adjoining splice flaps.
  4. Attach and secure the factory end caps to seal the barrier ends where each joint run begins and ends.
  5. Insert IVB into joint opening (interior side label facing inward) sufficiently to fit expansion joint assembly.
  6. Apply Flexible Seal Sealant (1/4″ x 1/4″ bead) between the integral mounting rail and the substrate on sizes over 6-inches wide. Sizes 6-inches and smaller use Microwaterseal Tape to seal the barrier to the substrate.
  7. Secure mounting rail with anchors to inside of structural joint opening.
  8. Refer to the IVB Series Install Guide for detailed step-by-step instructions.
