  4. 4. Course Objectives • Describe how rainscreen cladding systems work to reduce moisture penetration on a building’s envelope. • Define Exterior Grade Phenolic (EGP) and explain the manufacturing process. • Analyze Third Party performance criteria for EGP and describe the evaluation methods of the three tests most commonly required by building codes. • Observe how EGP can be fabricated and explain proper methods for handling and storing EGP panels. • Examine and discuss installation practices for EGP and identify incorrect installation methods that could compromise the effectiveness of a rainscreen cladding solution. • Observe various types of projects where EGP has been successfully used. 4
  5. 5. 5 Rainscreen: A Brief Overview
  6. 6. The Rainscreen Principle 6 Rainscreen
  7. 7. Rainscreen Principle 7 EGP PANELS ARE DESIGNED TO REBUFF RAIN FROM THE BUILDING’S EXTERIOR. VERTICAL SEAMS, WHICH ARE NECESSARY FOR THERMAL EXPANSION OF PANELS, ARE DOUBLY PROTECTED BY "HAT" PROFILES. EGP PANELS SERVE AS A RAINSCREEN, PREVENTING MOST RAIN FROM REACHING THE EXTERIOR FACE OF THE BUILDING. CONVECTIVE CURRENTS BETWEEN EGP PANELS AND THE BUILDING’S EXTERIOR HELP TO EVAPORATE WHAT LITTLE MOISTURE MAY ACCUMULATE ON THE BACK-SIDE OF THE PANELS. CLADDING THE BUILDING WITH EGP PANELS MINIMIZES THE AMOUNT OF RAIN AND MOISTURE THAT CAN INFILTRATE THE WATER-RESISTIVE BARRIER ON THE EXTERIOR OF THE BUILDING, EXTENDING THE BUILDING'S DEFENSE AGAINST WEATHER, MOLD, AND OTHER MOISTURE- RELATED ATTACKS.

  47. 47. 47 How to Handle EGP
  48. 48. Shipping EGP 48
  49. 49. 49 When removing EGP panels from pallets, each panel should be lifted directly up. Do not slide panels off of the stack as sliding may scratch or damage the panels.
  50. 50. 50 • EGP panels should be stored horizontally on shelving that enables the panels to lie flat and provides complete support. • A weighted panel should be placed on top of the panels if stored for an extended period of time. • Do not stagger panels and ensure that panel edges do not hang over the rack edge.
  51. 51. 51 • When transporting panels to job site, make sure the panels are properly packaged, strapped and protected. • Use cardboard under strapping to ensure the strapping doesn’t damage the panels. • Use corner guards to further protect the panels. • Do not store panels outside for any extended period of time.
  52. 52. 52 Never store EGP panels vertically as this may damage panels. For temporary storage outside, cover the panels well to protect them from climatic elements and to avoid moisture penetrating and accumulating between the panels.

  73. 73. Parameters to Keep in Mind with EGP • EGP panels are secured to vertical channels that are anchored to the inner wall, typically with the use of exposed screws. • Joints are left open so the movement of the panels is never restricted. • Since moisture will make its way to the inner wall, a moisture and/or air barrier will be needed. Consult your “barrier” representative to specify the correct type for your local geographical area and building requirements. • A minimum 1” air space must be left between the back of the EGP panel and the inner wall to enable the air movement required for the cavity to dry. 73

  77. 77. Correct Installation Incorrect Installation Panel to Profile Relationship 77 Required panel installation gap Panels can not be installed in a manner in which the panel is bridging a gap between adjacent typical profiles
  78. 78. Why Stainless? • Corrosion on the head can cause rust streaks. • Corrosion of the threads/shank can cause safety issues. • Corrosion of the head can cause pull-over problems. 78
  79. 79. Corrosion 79
  80. 80. Proper Panel Layout Technique Proper Panel Layout Technique Proper Panel Layout Technique Improper Panel Layout Technique Improper Panel Layout Technique Panel Direction 80
  81. 81. Panel Direction • Panels have a Top & Bottom. • Manufacturers will clearly note this by placing arrows on the protective film. • Panels that are inverted during installation may appear to have shading differences, called the “Sunrise/ Sunset effect”. 81
