Flashing Tapes

Adchem's NewFLASHTM and DrainFLASHTM are self-adhered, waterproof flashing products for flashing doors, windows and other openings of the building envelope designed and manufactured with new sealant compatible, clean, neat, materials offering new levels of protection from water, mold, mildew and rot.

Proven high performance pressure sensitive adhesive systems provide a broad range of performance, excellent sealant/adhesive compatibility and are easy to install in both cold installation temperatures to 20 oF and high temperatures where other products become difficult and messy. The adhesive is bonded to a conformable lightweight cross linked closed cell PE foam and will adhere well below 0 oF and at temperatures over 180 oF. The product weighs 60% of competitive butyl systems.

There are two different proprietary face sheets, one for NewFLASH , a 3 mil polyethylene face sheet co- extruded to the foam core for application in relatively dry areas. DrainFLASH uses the same foam and adhesive with an embossed non directional pattern on the surface of a 10 mil polyethylene film. Both products are tough, durable and provide leak protection resealing around nails and staples. Going beyond simple water barriers DrainFLASH provides a way to drain water and provide drying from behind trim and cladding. We provide construction site durable non-tear film release liners.

Test Method:

AAMA 713-08 Voluntary Test Method to Determine Chemical Compatibility of Sealants and Self-Adhered Flexible Flashings

Requirements:

  • No observed liquefaction or visible degradation of self-adhered flashing or sealant.
  • No slump exceeding limits described in 9.2.b.
  • No extreme discoloration.

Results:

DrainFLASH and NewFLASH meet all requirements on all sealants tested to Level 3 aged at 176 oF. Some slump was noted on a few sealants but not more so than the control panel.

DrainFLASH - Drain Plane Function Drain Rate Testing

Test Method:

This test method is a modification of ASTM 2273. The purpose is to establish the drain rate of water that is shed off building trim and cladding that comes into contact with the flashing system. The test measures the rate of flow from a given flashing system when installed over the nailing fin simulating, by use of a clear plexiglass sheet, and the installation of cladding and trim boards. The rate of drain is calculated by introduction of water into the horizontal chamber and timed and weighed. The measure is then calculated in gallons per hour of drain.

Results:

Drain Rate with both edges sealed

  • 4 Inch > 2 gallons per hour
  • 6 Inch > 3 gallons per hour
  • 9 Inch > 4.5 gallons per hour
