solid wood subfloor. this type of subfloor is common on older homes. as with plywood subfloors, if there is movement or squeaks, refasten the subfloor to the joists and set protruding fasteners into the subfloor. the boards should be no wider than 6 inches and installed on a 45-degree angle.
other than solid wood. sheathing materials fall in this category9 experimental procedure . material . sheathing type materials studied here were plywood, hardboard, particleboard, in-sulation board, and gypsum board. exterior a-c grade douglas-fir plywood, sanded both sides, was evaluated in three thicknesses--3/4,1/2, and 3/8 inch. plywood
is the material attached to the roof rafters. the base material can consist of solid wood sheathing, plywood-type materials, corrugated metal and other materials. 1bdiaphragm nailing plywood sheathing is installed so the 8 dimension of the plywood crosses the rafters or joists and the 4 dimension parallels the rafters or joists.

watch out: having inspected quite a few wood shingle roofs, we find that wood shingle roofs nailed directly to solid plywood or osb sheathing that is with no ventilation, battens, etc , while a permitted practice, produces much shorter wood shingle life, sometimes showing severe deterioration: splits, curls, cracks, lost shingle fragments, in as few as four years after new construction - ed.
types of plywood different types of plywood contain different numbers of layers, or plies, with three being the minimum. typically, one side of the panelits facemay be left unfinished. the back side is less pleasing to the eye.
