PM-EIFS Details

Typical PM Insulation Layout

  1. Structural Frame
  2. Sheathing
  3. Extruded Polystyrene XPS
  4. Foundation
  5. Casing Bead with Starter Strip
  6. Welded Wire Corner Aide or Corner Bead

NOTES:

  1. 2 lb/ft density expanded polystyrene (EPS) in compliance with ASTM C578-87a also suitable.
  2. Shallow “V” Surface Mount Control Joint used within 150 ft panels for stress relief.
  3. Deep “V” Expansion Joint used to divide walls into panels of maximum 150 ft and at floor lines with limited movement (less than 1/4″ [6mm]). Length to width ratio of panels defined by joints not to exceed 2:1.
  • Expansion Joint used at joints in existing construction, dissimilar materials or construction, floor lines, changes in building height, and other locations of anticipated building movement.
  • Casing bead used around perimeter of windows, doors, and other penetrations through the system

Control & Expansion Joint Locations

JOINT KEY

DV – DEEP V CONTROL JOINT

Uses:

  • To divide wall areas into panels 150 square foot maximum area with maximum dimension 18 feet.
  • Floor lines and dissimilar substrates
  • At masonry wall joints. If adjacent masonry wall segments are on a common foundation and maximum movement is 1/4″

SV – SHALLOW V SURFACE MOUNT CONTROL JOINT

Uses:

  • Inside 144 square foot panels for:
  • Stress relief at window and door corners
  • Color separations
  • Aesthetic Effects

EXPANSION JOINT

Uses:

  • At isolation joint in the substrate
  • At new construction joined to existing construction
  • All locations of movement greater than 1/4″

 

 

DV: Deep V Control Joint Section – PM

Reinforcing mesh may be placed under flanges on zinc control joint beads.

 

 

SV: Shallow V Control Joint Section – PM

Note: SV “Surface V” Control Joints do not provide the same stress relief capabilities as DV Joints. For limitations of use, please see the Joint Key.
