Rain Screen Wall Vent

[tbasc]

Does anyone know of a manufactured item to close the bottom of a rain screen wall system? I'm working on a wall made up of sheathing / 1" rigid insulation /

3/4" vertical furring strips / lap siding.

Look at some of the EIFS products - same idea. There are a number of flavors of perforated vinyl starter strips in various profiles. There should be one that does what you need. If not, you'll have to bend something up out of aluminum coil stock or some bendable vinyl.

Usually rainscreen walls are vented at the top and bottom. You would typically have a prepainted steel flashing at the bottom of the lap siding with a minimum 3/4" vent gap to allow air to circulate between the lap siding and the rigid insulation. There is also an L shaped piece of galvanized vent screen installed to prevent birds and bugs getting into the vent cavity at top and bottom.There should be a weather barrier membrane such as delta facade or air outshield installed between the rigid insulation and the furring so that any humidity can pass into the vented air stream to prevent mould buildup.

These are general conditions, would need to see how the wall terminates to give a better answer.

All the best

I use Cora Ridge strip vent for many differing applications. It is easy to use, nail able, cuts easy, and does not rust. It comes in a 1" profile. john
