EZEE Dam Window Pan Drainage Dam Water Shed Systems


Canadian manufactured EZEE Dam Window Pan Drainage Dam system consists of PVC extrusions which are installed on the sill plate and 4" up the jambs of window rough opening framing in wood frame construction. EZEE Dam is installed before the windows, providing a guide to window installers of correct installation location. The top surfaces of the extrusions slope to the outside, facilitating water migration to the exterior. The PVC material and hollow extruded construction resists thermal transfer.


In addition to being a BUILT GREEN® Approved Product, EZEE Dam Window Pan Drainage Dam can contribute to a building's LEED certification by assisting to achieve compliance with LEED requirements within Energy & Atmosphere, Materials & Resources, Indoor Environmental Quality, and Durable Building.

It has a 10 year warranty against water leaks or damages caused by water leaks in the pan area, which is backed up by an insurance policy that covers if Ezee Dam is installed as per manufacturers instruction with an approved peal and stick flashing membrane.


  •  helps projects achieve higher energy efficiency by providing a system to not only maintain positive drainage (moisture below windows is directed by positive drainage slope toward the exterior), but also by facilitating correct installation of windows with continuous air tightness and insulation layers of the wall system, helping to ensure comfortable draft-free indoor conditions, optimal for thermal comfort.
  • made from 100% PVC, which includes at least 20% recycled content, and is designed to minimize the need for trimming on site by providing standard 8 ft. lengths and pre-made corners.
  • does not require off-gassing adhesives, sealants, paints or coatings, and is compatible with all low-VOC adhesives, sealants, paints and coatings, which could be required by other elements of the window and wall systems.
