Sturdi-Strips™ Furring Strips
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 Sturdi-Strips hold your siding away from the wall to allow trapped moisture to drain away. Match Sturdi-Strips with Cor-A-Vent's SV-3 Rainscreen Siding Vent to create the Siding Vent System.**
** 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.

A: On stud spacing with 16-inch centers, you would need 1 linear foot of Sturdi-Strip for every square foot of wall –> for 500 sq. ft. of wall, you would need 500 lin. ft. of Sturdi-Strips. For 2-foot on center spacing, you would need 80% of that number – just take your square foot total and multiply by 0.8 –> for 500 sq. ft. of wall, you would need 400 lin. ft. of Sturdi-Strips.
