Conklin Flexion™ – Single Ply Membrane System

Product Description

Flexion™ is Conklin’s Single Ply Membrane Roofing System. Naturally fire-resistant, this thermoplastic membrane is based on a unique chemical composition and is fortified with DuPont® and Elvaloy® for improved lifespan, toughness, and flexibility. 

Working equally well on new and ageing roofs, the membrane:

  • Improves Roof Life
  • Resists Hail, Wind, and other destructive weather forces
  • Offers Top-Class Leak Protection
  • Carries ENERGY STAR® Certification for Lowering up to 30% of HVAC Energy Bills
  • Withstands Fire with UL Fire Rating
  • Can Be Easily Installed at All Times of the Year
  • Comes with up to a 25-Year Warranty that gets Renewed with Coating System
  • Resists Dirt and Discoloration
  • Gives Top Performance in All Seasons
  • Is Certified by Major Code Approval Institutions
  • Requires Minimal Maintenance
  • Can be Re-Coated Repeatedly to Avoid Expensive Roof Replacements in the Future

This membrane system is devised for structures that support lightweight roof assemblies and can be applied over a number of different types of roof decks.

The membrane saves HVAC energy costs by reflecting as much as 84% of the sun’s heat. And the ENERGY STAR certification may make you eligible for tax benefits, depending on your location. Through this and lower maintenance requirements, the membrane could pay for itself within the warranty period.

    The responsibility of executing all the mentioned precautions and guidelines rests with any or all the following parties:

    • Owner / Owner’s Representative
    • Roofing Contractor
    • Professional Roof Designer

    Before Installation

    • Employ only those personnel trained in the:
      • Application of Conklin Flexion roofing membrane
      • Relevant safety rules at the local, state, and federal level
    • Plan the installation carefully because you have to:
      • Install only the amount of roofing system, including the flashings, as you can make weather-tight on that very day
      • Avoid exposing the interior of the building and the contents therein to the effects of inclement weather
      • Prevent the use of the newly installed area as a zone for moving equipment, storage, or movement of personnel. If some movement is unavoidable, use polyester felt, plywood, and other approved barriers to separate the affected zone
    • Because this membrane system is made for structures that support lightweight roof assemblies:
      • Check thoroughly if the structural support mechanism is strong enough
      • Do not overload the roof deck or structure
    • Roofing substrate must be:
      • Capable of resisting a minimum force of 175 pounds-per-lineal-foot (2.5 kilo-Newton-per-meter) in any direction
      • Solid, structurally sound, smooth, and clean
      • Resistant to ponding of water
      • Free from ice and snow; debris, dirt, dust, moisture, solvents, fats, grease, oil, chemicals, and other contaminants; sharp edges, flaws, and loose and foreign material; ridges, blisters, and irregularities
    • For lightweight roof deck assemblies, retrofit jobs, and re-roof projects, perform pull out tests before installing the new membrane to ensure adequate pull out value for the roofing system:
      • Conduct the pull out test at the location where the membrane insulation is attached to the substrate
      • Required minimum number of pull out tests per project: (a) 10 for an area less than 50,000 sq. ft.; (b) 1 test for each 5,000 sq. ft. area greater than 50,000 sq. ft.
      • Distribution of pull out tests over the roofing area: (a) Take 60% of pull out tests in the defined perimeter / roof area / corner zone of the building; (b) conduct 40% of pull out tests in the defined field zone of the building / roof area
      • You will need to make customized modifications when installing the membrane: (a) in areas of wind zone four or higher as defined by the Factory Mutual Loss Prevention Data Sheets 1 to 28; (b) when internal air pressure on the lower side of the product is 2.6 pounds-per-square feet (lbs/sq. ft.) or higher; (c) at peculiar site conditions
    • Secure all equipment, accessories, and temporary and new construction in a manner that makes them immune from wind damage or wind blow-off
    • Eliminate all obstructions from roof drains and soil pipes
    • Remove the existing membrane and/or insulation, disintegrated wooden blocking, membrane flashings, and related metal flashings

    During Installation

    • Make sure that the membrane is damage free
    • Install the stock board
    • Roll out the membrane in the direction of water run-off
    • Ensure that the membrane seams overlap
    • Weld the overlapping membrane seams with a robotic welder or by hand
    • Use urethane sealant to seal off free membrane edges
    • About temporary water stops:
      • Install temporary water stops at the end of each day’s work or as required to negate the effects of inclement weather
      • Remove these before starting work on the next day
      • Dispose the collected water in a manner that does not damage the new roof system
    • When using solvents, cleaners, and solvent-based adhesives around air in-takes, take extra precautions as the odor of these can cause inconvenience to the occupants of the building
    • Dispose all the waste resulting from the project work in a manner that complies with the relevant regulations

    Storage Requirements

    Store the membrane rolls such that they are:

    • In a horizontal position
    • Protected from direct sunlight, rain, freezing, and construction operations
