  1. EIFS ApplicationsIntroduction to EIFS Components

  2. Some of the Players Registered Names and/or Trademarked elements of their respective companies or parent companies

  3. What is EIFS? • Exterior Insulation and Finish System Also called: • Synthetic Stucco

  4. Sheathing Secondary Barrier Joint Reinforcement Drainage Mat/Lath Adhesive / Base Coat Insulation Board Mesh Finish Coat / Texture Mechanical Fastener EIFS is a System

  5. What type of EIFS? • Barrier • Drainable • Panelized • Pressurized • Direct Applied

  6. Barrier vs Drainable Walls Barrier System Drainable System

  7. Drainable Systems

  8. Barrier Systems • Substrate • Joint Treatment • Weather Barrier • Cementitious Adhesive • EPS Board (Foam) • Base Coat • Mesh • Finish

  9. Systems Compared Barrier System Drainable System

  10. Framing Sheathing EIFS Contractor Sealant Contractor Roofer(s) Glazers Installers Any Penetrations EIFS is a Total System!

  11. Design Phase? Submittal Review? Ongoing Inspections? Product Selection? Pre-Con Briefings? Repair Reviews? Client Education? When are we most important?

  12. Design Elements Submittals Compatibility Coordination Manufacturer’s Input Mock-up Details & Testing Pre-Construction

  13. Incorrect Specs Mismatched Materials Poor Moisture Management Poor Communication Design Problems

  14. Complex Projects

  15. During Construction Post-Construction Damage Specific Repair and Maintenance Importance of Inspection

  16. Trade Education Materials Installation Techniques Trade Coordination Safeguarding Repairs During Construction

  17. Storage and Handling

  18. Results of rough handling

  19. Poor Fit = More Work!

  20. Educate the Trades

  21. Protect Repair Monitor other trades When the EIFS is Finished

  22. Penetrations sized for repairs and proper sealant joints Penetrations – The Good

  23. No allowance for mesh repair or a sealant joint. Penetrations – Not-so-Good

  24. Check the Specs

  25. Specifications and Instructions are rarely available in the field. Sad Painful Truth

  26. Inspecting Existing EIFS • Bulges or Cracks in Finish • Sealant Joints around doors, windows other penetrations • Staining or discolored finish around joints • Does the EIFS contact the ground or hardscape? • Where EIFS and roof lines come together • Sealant Joints • Flashing

  27. What to watch for - Cracks

  28. What to watch for - Flashing

  29. What to watch for - Damage

  30. What to watch for - Damage

  31. What to watch for - Damage

  32. What to watch for - Substrate Incorrect Correct Proper substrate on non-vertical surfaces

  33. What to watch for - Substrate Poor Fastening Delaminating Contamination

  34. What to watch for – EPS Foam Proper Adhesive Pattern Interlocking Corners

  35. What to watch for – EPS Foam Correct Incorrect No gaps should exist in the EPS when the base and mesh is applied!

  36. EPS is Thermally Stable The cementitious adhesive expands and contracts with temperature changes.

  37. What to watch for – Base Coat Too thick.

  38. What to watch for – Base Coat Too thin.

  39. What to watch for – Base Coat Damage To Mesh.

  40. What to watch for – Finish Finish coat has not adhered to the base coat. Why? Application? Product Failure? Environmental Condition?

  41. What to watch for – Finish Finish application issues.

  42. What to watch for – Sealant Joints Sealant is too thin. Backer rod is too shallow. Creative installation of backer rod.
