Butt jointed boards should be fitted with a 5mm gap to allow airflow. Ventilation gaps of at least 16mm should be provided at the top and bottom of the cavity. Horizontal cladding should be cut to ensure a minimum 8mm gap before vertical members of windows, doors, corner trims or similar.

Frequently Asked Questions
What is the required space between hardboard panels when used as siding?
50 mmA clearance of not less than 50 mm shall be provided between a roof surface and cladding that is adversely affected by moisture, such as untreated wood, plywood, OSB, waferboard and hardboard.
What is the gap for sheathing?
APA recommends a 1/8-inch space between panel edge and end joints. Plywood and oriented strand board (OSB), like all wood products, will expand or shrink slightly with changes in moisture content. If the wood structural panels are tightly butted, there is no room for expansion and buckling can occur.
How is exterior cladding supported?
The small strips of wood that support the exterior covering are called laths. They also create an air pocket between the exterior finish and the air barrier.
Should siding go all the way to the ground?
In most cases, siding clearance should be about 6-8” from the ground. If it's done improperly, the siding may be too close to the ground, which will invite insects, pests, and other types of damage.
What should the gap be between wall and cladding?
A moisture gap (or cavity) behind the cladding is the single most important factor in the success of the cladding installation, and a 20mm gap between the cladding and wall is the minimum that we would advise. The purpose of this cavity is to ensure air circulation behind the boards.
What is the gap called between exterior wall and roof?
The horizontal gap is typically not there. as Lee Sam mentioned, counter flashing should be there, but I hope is still there deeper inside the recess. For some reason the builder decided to set the brick on a steel lintel (beam of a sort) above the roof, instead of below the roof where this space would not be seen.
How does Shadow Gap half lap cladding work?
Horizontal Shadow Gap Half Lap Cladding is a variation to the standard profile without the Tongue & Groove. Instead the timber is just rebated at the rear for each piece to slide into on another. This profile creates a softer 10mm wide V shape shadow line.
How big is a gap in the wall?
Reservoir cladding systems, such as brick veneer, often war- rant a more robust drainage component in the exterior wall assembly. This is often code-mandated to be at least 1 inch in thickness. This gap is formed by using brick ties to stand off the brick veneer from the WRB and exterior sheathing.
