Can i use 3/8 cabinet grade plywood for siding
If exposed to the elements without extensive and "expensive" weather treatment it will not survive long under the onslaught of UV rays, rain, sleet, snow, or even salt water condensate near if your're the sea shore.
Yes... but isnt it more expensive?
You can use the 3/8" cabinet grade plywood for siding. You can also use it with pre-milled clapboard siding. The cabinet grade plywood has to be pre-cut to fit.
