What is a V-joint

Definition of V-joint in Construction

The term V-joint is used in construction to reference a joint that is normally between panels, or repeated products, such as siding, flooring, etc. The V-joint is an intended manufactured or constructed joint that will occur in different finish materials on a project. In most instances the use of a V-joint eliminates the need to perfectly align materials if they had a square edge. The V-joint hides the actual meeting of the two surfaces, below the surface of the installation, and makes any type of misalignment or imperfection in the edges of the material hidden in the bottom of the V-joint. In many instances the final V-joint is filled with a material to create a smooth surface between the two edges. If the V-joint is filled, the V joint profile will allow more stable joint filler, due to the profile of the V joint. When any joint is filled, the more material that is inherently on the upper surface of the joint, with lesser material as the joint deepens, will allow a more stable final application. Similar to the V-groove, which is a cut groove into any cracks or imperfections in a masonry surface, the profile of a V joint will allow the joint to withstand deterioration and cracking.
