What fiber-cement siding installation includes

| What the source says | Where it comes from |
|---|---|
| DOE Building America, wall drainage guidance: “This space creates a capillary break, which prevents water that wicks through the siding from being absorbed into the water-resistive barrier.” | U.S. Department of Energy, Building America Solution Center, read 2 November 2026. |
| DOE Building America, wall drainage guidance: “The air space also allows air to flow freely behind the siding, which increases the wall's ability to dry.” | U.S. Department of Energy, Building America Solution Center, read 2 November 2026. |
Describe the fiber-cement product and rain screen assembly together in the job you post on InstaBids.
