About this deal
Sizes To Fit Your Panel Edges: We offer these in 7/16, 15/32, 1/2 inch sizes, ensuring these will be a snug fit for your roofing or walls.
You need as many H-Clips for OSB sheet boards as you need for plywood boards. This means you need one at the approximate middle point between each vertical framing member for 16-inch center framing and two H-Clips for 24-inch centered framing. Seek professional advice if you’re unsure. Installing H-Clips on Existing Roof The main purpose of H Clips is to increase panel stiffness, enabling better load distribution between adjacent panels. As a result, the stiffer panel edges are unlikely to experience structural defects when subjected to heavy loads near the edges. This may seem like a lot of money – and it is. However, it’s worth it, given that H-Clips significantly reduce the cost of installing a new roof. For instance, they reduce the number of materials needed, such as rafters. Plywood Clips are not required for all roof sheathing projects, but they are recommended. They improve the longevity and durability of the plywood by ensuring that the plywood doesn't shift and become uneven over time. What are plywood clips used for?If the root cause is missing H-Clips, install the clips and reinforce the saggy roof section. Also, replace the sheathing with stronger boards to eliminate the problem. H-Clips for Roof Sheathing Spacing Unsurprisingly, H-Clips are used in many other applications beyond roofing. For instance, you can use H-Clips on ramp-style flooring projects and slanted walls. Again, the clips provide additional stiffness, reducing the risk of flexing, especially at the edges. The supported slanted walls or ramp-style floors can remain for a long time without structural issues.
Also Works For OSB: The H clips also work great for oriented strand board (OSB). OSB is an engineered wood panel that is used interchangeably with plywood. H-clips provide additional stiffness between bearing points for the unsupported edges of wood panel (plywood or OSB) roof sheathing, along with the necessary 1/8” gap for expansion, as shown below illustrated on a bag of Simpson H-clips. Some older H-clips do not provide a built-in gap. Also see our blog posts Are H-clips required by the building code for roof sheathing? and What causes a lump or dip in the roof? In addition, the absence of H-Clips can cause the roof to sag between trusses. However, you want first to rule out other potential factors, like an extra thin sheathing or incorrect span between trusses. Improperly installed panels can also cause saggy roofs.Also known as panel edge clips or plywood H clips, H Clips are metal clips that hold adjacent wood panels together while providing an expansion gap. H-Clips are metallic panel clips for joining adjacent sheathing panels, especially on shingle roofs. The International Building Code requires them. However, most local building codes don’t mandate them.
