Sometimes construction projects present out-of-the-ordinary challenges. In this video, Matt Risinger, master builder and Corey Ball, a DuPont Tyvek rep discuss how to flash a specific window correctly. The result was Risinger's first use of Fluid Applied Tyvek that was made for unique applications such as that in the video. Using a sample board, Corey describes Fluid Applied Tyvek, a solidified membrane that is akin rolling on a polyurethane seal. The result is a sealant that feels like a polyurethane elastomeric seal that you would normally find on expansion joints. Risinger compares it to a bedliner, a rubberized-looking membrane. This Tyvek is an air and water barrier and should the wall that the Tyvek is on get some moisture on it, the moisture will actually dry through the Tyvek. It is available in a large container so that the product can be rolled on if it is being used in large areas. For smaller areas, there is a more viscus version and a thicker joint compound which needs to be smoothed when applied. Catch the video so that you're prepared the next time you're faced with a non-standard window.
