Although this installation method is not recommended it is important to ensure that if this method is used the vertical seams must overlap by at least 6″ and taped with DuPont™ Tyvek® Tape. This will provide the greatest level of air infiltration and bulk water holdout protection. Recommended installation instructions can be located on this website or the roll label affixed to the product.
