Water vapor permeable ribbed membranes and related systems and related methods

A building envelope system comprising:

• a building frame structure;
• at least one panel member;
• wherein the at least one panel member is secured to the building frame structure;
• a first water vapor permeable ribbed membrane;
• and
• a second water vapor permeable ribbed membrane;
• wherein each of the first water vapor permeable ribbed membrane and the second water vapor permeable ribbed membrane comprises:
• a top surface;
• a bottom surface opposite the top surface;
• and
• a plurality of ribs located on at least the bottom surface;
• wherein the bottom surface has:
• a first edge portion,
• a second edge portion opposite the first edge portion,
• a third edge portion extending between the first edge portion and the second edge portion, and
• a fourth edge portion opposite the third edge portion and extending between the first edge portion and the second edge portion;
• and
• an adhesive layer located on the plurality of ribs;
• wherein the adhesive layer covers at least a portion of the plurality of ribs;
• where at least a portion of the adhesive layer has a thickness that is less than a rib height of the plurality of ribs such that a portion of the plurality of ribs is exposed through the adhesive layer;
• wherein the adhesive layer of the first water vapor permeable ribbed membrane adheres the first edge portion of the first water vapor permeable ribbed membrane to the second water vapor permeable ribbed membrane;
• wherein the adhesive layer of the first water vapor permeable ribbed membrane adheres the first water vapor permeable ribbed membrane to the at least one panel member;
• wherein the adhesive layer of the second water vapor permeable ribbed membrane adheres the second water vapor permeable ribbed membrane to the at least one panel member.
