Where should continuous expansion joints be installed?
• At building expansion joints. • At substrate expansion joints. • At floor lines in wood framed construction. • Where the Standard System abut one another. • Where the Standard System abut other materials. • Where significant structural movement occurs, such as: • Changes in roofline. • Changes in building shape and / or structural system. • Where the substrate changes. SUBSTRATE MOVEMENT AND EXPANSION AND CONTRACTION OF THE SYSTEM AND ADJACENT MATERIALS SHALL BE TAKEN INTO ACCOUNT IN THE DESIGN OF EXPANSION JOINTS, WITH PROPER CONSIDERATION GIVEN TO SEALANT PROPERTIES, INSTALLATION CONDITIONS, TEMPERATURE RANGE, THERMAL COEFFICIENTS OF MATERIALS, JOINT WIDTH TO DEPTH RATIOS, AND OTHER MATERIAL FACTORS. Q: Does Parex require an expansion joint at all floor lines? A: At wood framed buildings only. Unless there is a Web Truss floor joist, wood l-beam Truss- joint type, or Laminated Veneer Lumber floor joist, then there is no expansion joint needed. Q: What is the minimum space required
