SV-3 Siding Vent

 

A 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 7/16” thick SV-3 Rainscreen Siding Vent solves these problems with a minimum amount of work and expense.

Match the SV-3 with Cor-A-Vent’s Sturdi-Strips polyproylene furring to create the Siding Vent System – the first commercial rain screen system on the market. The first part of the system is the heavy-duty Sturdi-Strip furring strips, which hold the siding away from the wall, creating the necessary minimum capillary break (3/8” or 10mm) that will allow moisture to drain away instead of becoming trapped. The SV-3 at the top and bottom of the walls will let that moisture drain out and allow fresh air to pass through, keeping the system dry, all while keeping insects out. The Siding Vent System was designed to last and will not crush or compress like competing “drainage mat” rainscreen products.

Q: How much SV-3 do I need?
 
A: SV-3 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-3 you will need.
