Abstract

The present invention provides for a fluid control assembly comprising a fluid control film comprising a first side and a second side, the first side comprising a microstructured surface with a plurality of channels on the first side; and an exterior building wall assembly comprising a substrate layer having a major surface, the substrate major surface associated with the fluid control film.

Claims

1. A fluid control assembly comprising:

a fluid control film comprising a first side and a second side, the first side comprising a microstructured surface with a plurality of channels on the first side; and

an exterior building wall assembly comprising a substrate layer having a major surface, the substrate major surface associated with the fluid control film.

2. The fluid control assembly of claim 1 wherein the substrate major surface is associated with the first side of the fluid control film.

3. The fluid control assembly of claim 1 wherein the substrate major surface is associated with the second side of the fluid control film.

4. The fluid control assembly of claim 1, where the fluid control film is moisture vapor permeable.

5. The fluid control assembly of claim 1, further comprising a non-woven layer associated with the first side of the fluid control film.

6. The fluid control assembly of claim 1, where the substrate is a sealed insulated panel.

7. The fluid control assembly of claim 1, further comprising adhesive on the on the second side of the fluid control film.

8. The fluid control assembly of claim 7, wherein the adhesive is a continuous layer.

9. The fluid control assembly of claim 7, wherein the adhesive is discontinuous.

10. The fluid control assembly of claim 1 wherein the substrate is a frame for a defined opening.

11. The fluid control assembly of claim 10 wherein the frame is a window jamb.

12. The fluid control assembly of claim 10 wherein the frame is a doorjamb.
