Cladding installation involves several steps in order to reach the optimal result, and an important consideration in this process is the cladding clearance.  This refers to the gap or space maintained between the cladding material and other building components, surfaces, or features.  This clearance is crucial for ensuring proper performance, durability, and safety of the cladding system.  Here are some common types of cladding clearance:

1. Ground Clearance

• The distance between the bottom edge of the cladding and the ground surface (e.g. soil, plants, paving, or concrete).
• This ensures protection from moisture, splash back, and soil contact.
• Typical clearance is 150 – 200 mm (this varies by material and local building codes).

2. Roof Overhang Clearance

• The gap between the cladding and roofing materials to allow for proper drainage and to avoid water ingress.
• Always allow distance between trees and cladding as any vegetation right up against the cladding is not advisable.

3. Ventilation Gap

• The space left behind the cladding (in rainscreen or ventilated façades) to allow air circulation.
• This prevents moisture buildup and aids in thermal performance.
• Typical gap is 20 – 50 mm, depending on design.

4. Window / Door Clearance

• The spacing around openings to allow for expansion, contraction, and sealing.
• This ensures watertightness and thermal performance.

5. Expansion Clearance

• Allows for thermal expansion and contraction of cladding materials.
• This is crucial for metal, timber, and composite claddings.

6. Fire Safety Clearance

• Specific spacing may be required around fire-rated elements to prevent fire spread.

Don’t forget that there are key factors which influence clearance:

• Type of cladding material (e.g. wood, metal, composite, stone).
• Climate and environmental conditions.
• Local building codes and regulations.
• Manufacturer’s installation guidelines.

With careful advance planning and solid execution, your cladding will continue to perform well and shine brightly!
