SV-5 Rainscreen Siding Vent

Cor-A-Vent SV-5 Siding VentA simple, effective solution for rainscreen ventilation behind wood, hardboard & fiber cement siding.

Venting behind your siding is just as necessary and valuable as venting your attic. Trapped moisture from driving rain or condensation can cause major problems. Paint peels off, exterior sheathing gets wet, siding can warp and your house wrap becomes saturated.

The ¾” thick SV-5 Rainscreen Siding Vent keeps insects out while allowing moisture to drain away and drying airflow to pass behind the siding. SV-5 pairs with treated ¾” thick wood furring strips, or use a double layer of Cor-A-Vent Sturdi-Strips for a perfect match.** 

** In situations where exterior rigid foam insulation is being installed, Cor-A-Vent recommends using ¾” thick treated wood furring strips installed over the foam, screwed into the wall studs, to provide a structural fastening point for the siding, and the SV-5 Siding Vent installed at the top and bottom to supply the rainscreen drainage, airflow, and insect screen.

Q: How much SV-5 do I need?
A: SV-5 runs linearly along the top and bottom of the wall, as well as above and below windows or doors. Take the total length of all walls and multiply by 2 (for top and bottom), then account for above and below wall penetrations to determine how many linear feet of SV-5 you will need.
