Metal Siding Over Osb

Remove the siding and install oriented strand board commonly referred to as osb or to use the existing siding that s on the house now as substrate or layer beneath the top surface underneath the hardieplank siding.

Metal siding over osb.

To install vertical metal siding start by applying horizontal furring strips and sheathing to the surface you re working on if it s uneven. Think of roll formed steel roofing and siding as performing like a very strong very thin plywood and you will have a better grasp of how it performs. Work toward the ridge. It comes in a variety of finishes made to resemble various hardwoods and stucco surfaces.

There are two options for this. Osb is widely used as roof decking material. Overlap the edge of the roof by 1 inch. Although steel roofing and siding has recognized shear values just like osb oriented strand board and plywood there are times when the forces needing to be carried are greater than the capacity of the steel itself.

A homeowner recently wrote and asked me the following regarding osb roof decking. Oriented strand board commonly referred to as osb is a type of engineered lumber similar to particle board formed by adding adhesives and then compressing layers of wood strands. Then install the corner posts that came with your siding and nail j channel along the top and bottom of the wall. The only reason to put osb on a roof would be in the case of a very narrow very long very tall building with high wind loads ones which would exceed the wind shear carrying capacity of the steel.

For many applications a layer of plywood underneath your metal roofing is an unnecessary expense. The main concern to understand is that the hardieplank siding is going to be on the house for a very long time. If there are any windows or doors nail j channel around the edges of those as well.
