Ventilation screed device and assembly
View Patent ↗A ventilation screed comprising an upper attachment flange having a top portion and a bottom portion and at least one opening in the top portion; a drip edge protruding from the bottom portion of the upper attachment flange; a drainage cavity protrusion protruding from the bottom portion of the upper attachment flange above the drip edge, wherein the drainage cavity protrusion has a vertical portion of a L-shaped drainage trough portion and a bottom portion having at least one drainage opening along a meeting point of the upper attachment flange and the drainage cavity protrusion, an upper ground portion in communication with the L-shaped drainage trough portion and a drainage cavity shroud in communication with the upper ground portion, wherein the drainage cavity shroud extends past the drip edge.
1. A ventilation screed comprising:
an upper attachment flange having a top portion and a bottom portion and at least one opening in the top portion;
a drip edge protruding from the bottom portion of the upper attachment flange;
a drainage cavity protrusion protruding from the bottom portion of the upper attachment flange above the drip edge, wherein the drainage cavity protrusion has a vertical portion of a L-shaped drainage trough portion and a bottom portion having at least one drainage opening along a meeting point of the upper attachment flange and the drainage cavity protrusion, wherein each of the drainage openings is a substantially rectangular shape with two corners of the rectangular shape having rounded edges that are away from the meeting point of the upper attachment flange and the drainage cavity protrusion;
an upper ground portion in communication with the L-shaped drainage trough portion and a drainage cavity shroud extending substantially downward from the upper ground portion, wherein the drainage cavity shroud extends past the drip edge.
2. A ventilation screed as in claim 1 , wherein the drip edge is angled downward in a direction away from the upper attachment flange.
3. A ventilation screed as in claim 1 , wherein the drip edge has a shaped end selected from the group consisting of angled edge, rounded edge and rectangular edge.
4. A ventilation screed as in claim 2 , further comprising a flexible leg in communication with the drip edge.
5. A ventilation screed as in claim 1 , further comprising at least one friction bead along a portion of at least one of the upper attachment flange, the upper ground portion, the L-shaped drainage trough portion, the drip edge and the drainage cavity.
6. A ventilation screed as in claim 1 , further comprising a connector between two adjacent ventilation screeds.
7. A ventilation screed as in claim 6 , wherein the connector is a three sided connector that is smaller than and sits in a space between the drainage cavity protrusion and the drip edge of two adjacent ventilation screens.
8. A ventilation screed as in claim 1 , further comprising a screen parallel to at least a portion of the upper attachment flange.
9. A ventilation screed as in claim 1 , further comprising a mesh parallel to at least a portion of the upper attachment flange.
10. A ventilation screed as in claim 1 , further comprising a reticulated foam insert that installed is parallel to and between siding and the upper attachment flange.
11. A ventilation screed as in claim 1 , further comprising a joint connector, wherein a left portion of the joint connector sits in a first ventilation screed and a right portion of the joint connector sits in a second ventilation screed and the second ventilation screed is adjacent to the first ventilation screed.
12. A ventilation screed as in claim 1 , further comprising an insect screen in the L-shaped drainage trough portion.
13. A ventilation screed as in claim 1 , further comprising an end cap that covers a portion of the bottom portion of the upper attachment flange, the drip edge and the drainage cavity protrusion.
14. A ventilation screed as in claim 13 , wherein the end cap has an upper protrusion having a first horizontal portion, a first vertical portion, a second horizontal portion and a second vertical portion that extends above the first horizontal portion.
15. A ventilation screed as in claim 13 , wherein the end cap has a lower protrusion that is slanted downward substantially parallel to the drip edge.
