for Better Construction with True Economy

• Quality builders usually use wood sheathing for side walls, sub-flooring and roof boards. These builders, in explaining their framing methods, use such words as "strength, rigidity, tightnes-�.

Weyerhaeuser 4-Square Wood Sheathing is stiff" and strong, and because it is kiln-dried, it has remarkable dimensional stability. Wood has great nail-holding power. Accordingly wood sheathed side walls resist vibration, such as that caused by motor traffic. This nail-holding ability also permits the secure and economical application of wood sidings and shingles without furring strips.

The cell structure of wood sheathing permits a wall to breathe ... to take on and give off excessive moisture. With vapor-proof sealing paper on the inside of the studs, or with a vapor barrier

insulating blanket suspended in the stud space, and a wind-proof paper on the outside of the sheathing, a safe, dry, breathing wall is created.

Lumber is also the preferred material for sub-flooring and roof boards. It provides a strong base for applying finish materials, and, as roof boards, the strength to withstand snow and wind loads.

A broad selection of Weyerhaeuser 4-Square Lumber items is offered for use as wall and roof sheathing and sub-flooring. There are species, widths and grades to serve most building requirements.

Many builders find that it pays to remind home buyers of the advantages of lumber sheathing and to point out that the use of Weyerhaeuser 4-Square Kiln-Dried Lumber Sheathing provides proof of better building value.
