Incense cedar, grown mainly in Northern California and Oregon, is less abundant but readily available as fencing, siding and decking as well as pencil stock. Eastern red cedar, is used primarily for cedar chests and closet lining.

Now wood technology has produced a lap and panel siding product which is hard to distinguish from top grade cedar. Louisiana-Pacific Corp. has used an improved resin Waferwood formula to manufacture a product called L-P lnner-Seal. In addition to being similar in appearance to cedar, the product is considered durable, easy to work with. attractive and economical. Increased strength and stability come from the new formula. The products are made from 7/16 inch Waferwood with a resin-impregnated overlay embossed with a wood grain pattern.

The lap siding has eamed the American Plywood Association's siding performance rating. It is the first nonveneer siding product to achieve the rating, which is based on a stringent series of perforrnance tests conducted by the association. The new Inner-Seal panel siding is currently undergoing similar tests and is expected to receive the rating soon.

The lap siding is available in 16foot lengths and 6, 8,9-l/2 and l2inch widths. The panel version comes in 4x8, 4xl2 and 4xl6-foot sheets with a variety of groove patterns. All are primed and ready for painting.

New panel product has many of the qualities of kiln-dried solid wood...looks like cedar Louisiana-Pacific uses improved Wafenvood resin formula for new lap and panel siding products.

The new Inner-Seal resin produces a chemical bond with the cellulose in the wood fiber. Since water doesn't break down that bond, wafers with a higher moisture content can be used. That higher moisture significantly reduces any tendency the products might have to absorb moisture encountered after leaving the plant and arriving on the job site.

The new resin also gives the products improved physical properties with virtually no contraction, expansion or swelling problems.
