Top of mind when installing cladding should be the importance of clearance as it protects the building envelope by preventing moisture and environmental damage at the base of exterior walls, often very costly problems to repair down the road.

 

Key Reasons Proper Cladding Clearance Is Important:

• Moisture protection

Clearance keeps siding away from soil, standing water, and any other source of moisture.  This prevents water from wicking into the cladding, which can cause rot, swelling, or deterioration.

 

• Prevents structural damage

When moisture enters the wall assembly, it can damage sheathing, framing, and insulation, potentially leading to costly repairs.

 

• Allows proper drainage and airflow

A gap at the bottom of the cladding allows water to drain out and air to circulate, enabling the wall system to dry properly.

 

• Reduces risk of mold and decay

Persistent moisture behind siding can lead to mold growth and wood decay, which affects both building durability and indoor air quality.

 

• Protects against insects and pests

Keeping the cladding above the ground helps reduce access for insects, termites, and other pests that thrive in damp areas.

 

• Improves durability and lifespan of cladding

Correct clearance helps siding materials last longer by reducing constant exposure to moisture, dirt, and debris.

 

Proper cladding installation will not only keep moisture and dirt out and ensure proper drainage and airflow, it will also add years to your building’s gleaming appearance!
