What Is Rainscreen Siding?

Key Components in the Diagram

1. Foam Insulation

• Adds thermal resistance to reduce energy loss and improve the building’s energy efficiency.

2. Airflow

• The gap between the siding and the wall sheathing allows air to circulate, helping to dry any moisture that might penetrate the siding.

3. Housewrap

• A critical moisture barrier that prevents water from infiltrating the sheathing while allowing vapor to escape.

4. 1x Furring Strips

• These create the gap needed for the rainscreen by providing a mounting surface for the siding.

5. Corrugated Vent Strip with Insect Screen

• Ensures proper ventilation while preventing pests from entering the space between the siding and the sheathing.

6. Plastic or Metal U-Tap Over Bottom of Foam

• Prevents moisture from wicking upward into the insulation.

7. Decking

• Acts as the base structure for any exterior deck that might be part of the installation.

8. Flashing with a 5-inch Minimum Wall Leg

• Directs water away from the wall assembly to prevent water pooling and damage.

9. Self-Adhering Membrane

• Creates an additional waterproof barrier, particularly in critical areas such as behind the ledger board.

10. 2x Band Joist or 1-inch Engineered Wood Rim Joist

• Provides structural support for the deck and prevents twisting or warping.

11. Ledger Board

• Anchors the deck to the house. It must be properly flashed to avoid water penetration.

12. Drip Cap with 5-inch Minimum Wall Leg

• Directs water away from the wall and foundation, ensuring effective drainage.

Benefits of Rainscreen Siding

1. Moisture Management

• Reduces the risk of mold, rot, and deterioration by allowing moisture to escape.

2. Enhanced Durability

• Extends the lifespan of siding and structural components by preventing water damage.

3. Improved Energy Efficiency

• Proper insulation and ventilation work together to maintain a comfortable indoor temperature.

4. Better Pest Control

• Screens and sealed edges minimize the risk of pest intrusion.

5. Aesthetic and Structural Integrity

• Protects the building from unsightly warping, swelling, and decay over time.

When and Where to Use Rainscreen Siding

• Climates with High Rainfall

Essential in areas with frequent rain to ensure long-term protection.

• Homes with Decks

Prevents water damage around ledger boards and decking.

• Historical or Modern Homes

Offers a reliable solution for both traditional and contemporary building designs.
