  1. Tapered Insulation SystemsEdward Krusec, AIA, CSI, RCI RCI Mid-Atlantic Chapter May 11, 2006

  2. Roof Systems • Residential roofing - high slope • Not watertight • Sheds water quickly • Commercial roofing - low slope • Watertight • Sheds water slowly • Potential for ponding

  3. Water !!!

  4. Providing Drainage onLow Slope Roofs • Structurally sloped • Field shaped • Spray applied foam • Lightweight concrete • Board Stock • Cut • Perlite • Thermoplastic foams • Cellular glass • Fibrous glass • Molded • Polyisocyanurate

  5. Features of Tapered Polyisocyanurate Insulation • Size thickness from 0.5” to 4.5” • Slopes from 1/16” to 1/2” per foot • Typically 4’x4’ but 4’x 8’ is available • Variety of facings compatible with all roofing systems • Highest r-values per inch available in a roofing insulation

  6. Tapered Panels

  7. Tapered Profile Section Example

  8. Design Problem

  9. Many Options

  10. 4-Way slope

  11. Guaranteed Drainage Program A commitment by the insulation manufacturer to Provide: • Specification Development • Establish Design Criteria • Identify Field Parameters • Installation Assistance The result is a finished roof system which is void of standing water within 48 hours of rainfall.

  12. What Is a Roofing Cricket? Secondary applications of insulation directing water run off to the drainage points.

  13. Cricket Width “Rule of Thumb” The total width of a full diamond cricket shall be between 1/2 and 1/3 of the distance between the drains

  14. Cricket Definition

  15. Cricket Definition

  16. Cricket Definition

  17. The History of Roofing Crickets In the past contractors have fabricated crickets in the field • Concerns: • Labor intensive • Amount of waste and disposal • Field fabrication errors leading to material shortages

  18. Introduction of Custom Crickets Solved issues of: • Labor • Waste • Field fabrication • Concerns: • Turn around time/availability • Many small pieces to keep track of • Lack of flexibility in the field

  19. In Conclusion Proper roof drainage will result in substantial savings ! • Reduced roof maintenance • Less stress to the building structure • Extended roof life • Consistent insulation performance Work with an experienced tapered insulation design source----

  20. In Conclusion • DO NOT accept substitutes unless adequate new tapered layouts are provided with the submittal package • Make sure the system is installed per the submittals • Material shortages • Planes or ridges that don’t line up • A tapered layout that does not work
