Masonite Siding 101: Why It's Bad News
Moving into a new home is a great feeling of accomplishment. Fixer-uppers have been a trend in the real estate market for some time now, and for a great reason. Often minor cosmetic adjustments to homes can have a major impact. But what happens when you find a problem that isn’t so DIY-friendly? Discovering masonite siding, also known as "fiberboard" or "hardboard", may unearth more serious problems for an older home. Masonite Siding 101: Hardboard is an engineered wood product that is comparable to particle board. This product is made from compressed wood fibers so it does not have a grain like solid wood. However, a wood veneer may be formatted over the product so it appears to be solid. If you’re unsure if your siding is in fact masonite, check unfinished areas like the attic for manufacturer’s markings. Another way to tell that your home has Masonite is the way that it is deteriorating -- look for flakes, curls and swelling in damaged areas. Masonite is know for extensive use in various industries for its durability and flexibility. During the 1980s and 1990s this product was used as exterior siding for many new construction homes. It was widely used for its low cost compared to regular siding material. Why It's Bad News: As one could imagine, a product with fibers is easily susceptible to moisture damage. The compression process often leaves only one side of the product smooth which proves to be a greater risk for water issues. Over time, masonite swells and rots if continuously exposed to the elements. -

Itening Guide
itening Guide There are three essential tasks involved in the making of any woodwork project. The first is to cut out and shape the components; the second is the joining of those components; and the third and final task is the finishing of the article. This appendix provides you with information about the best ways to fasten your workpieces together, to ensure your project's long life. The options are between adhesives, nails, screws and bolts. NAILS Nailing is a quick, efficient and economical way of joining timber. lf the correct nails are chosen, there is no reason why the joints should not be durable. Timber framed houses, with most of the framing just nailed together, have stood the test of time. The listing of nail types that follows provides an overview of commonly used nails. This listing is not complete - nails exist for specific purposes such as boat-building, but these are outside the requirements of the normal handyman. _ Nail Types: Gommon Bullet Head: Used for hardwood framing and general fixing. Flat Head: Used for softwood framing, fixing softwoods or anywhere bullet heads would tend to pull through. Wire Brads: Small bullet head nails, used for attaching decorative mouldings. Clouts: Small nails with a relatively large flat head, used for attaching thin sheet material. Nail Types: Special Purpose Tacks: Used principally for upholstery; commonly blue- black in colour. Panel Pins: Used for fixing plywood panelling to timber framing; "brown" plated. Hardboard Nails: Used to attach hardboard ("masonite"); generally zinc plated. Plaster Board Used for fixing plasterboard to timber framing; Nails: zinc plated. -

Abstract Racking Performance Of
ABSTRACT RACKING PERFORMANCE OF PAPERBOARD AND WOOD BASED SHEATHING MATERIALS By Benjamin Ong A small scale (16 x 16 inch) racking tester was used to evaluate the racking performance of the paperboard and wood based sheathing materials. In this study it was shown that the staple spacing, staple size and caliper of the paperboard affect racking performance. It was established in this study that extending staples length beyond 1 inch has no advantage for the paperboard and wood based sheathing materials. Similarly, using nails for fasteners has no advantage both for paperboard and wood based sheathing materials. This finding is limited to the present set up and does not represent other racking testers. The racking performance improved when adhesive was used in combination with staples to attach the sheathing to the wood frame. It was observed after the racking test, the physical state of the paperboard sheathings indicate that staples have a higher withdrawal resistance and less tear through when compared to the nails. The stretching of the paperboards during the racking test slightly affects the tensile properties and further study is needed. The hardboard was evaluated to have better racking stiffness and strength than that of plywood and oriented strand board. The comparison of staples and nails as fasteners based on the racking stiffness and strength show that nail will be preferred for hardboard but for plywood and oriented strand board, either nails or staples could be used as fasteners. The basis weight and racking strength have an inverse relationship for the wood based sheathing.

Board Materials from Wood Residues
UNITED STATES DEPARTMENT OF AGRICULTURE • FOREST SERVICE • FOREST PRODUCTS LABORATORY • MADISON, WIS. U. S. D. A. FOREST SERVICE RESEARCH NOTE F PL -045 Rev. July 1971 1 BOARD MATERIALS FROM WOOD RESIDUES By WAYNE C. LEWIS, Engineer Forest Products Laboratory, Forest Service U.S. Department of Agriculture ---- About 9 billion square feet of various types of wood-base fiber and particle panel materials are manufactured each year in the United States. Wood sub stance in one form or another is the principal raw material for all hardboard and particleboard. About two-thirds of the insulating board produced also is wood based; the remainder is made from bagasse (waste from sugar cane) and waste paper. Use of these products has increased about 50 percent during the past 7 years so their potential for utilization of residues is most important. The total wood requirements for board manufacture based on plant capacity in 1970 are estimated at more than 16,500 tons (dry wood basis) per day. Total daily productive capacity in final board, including that from other agricultural fiber, is about 15,000 tons. Of this, at least one-half are residues from some other type of forest products manufacturing operation. Principal sources of residue raw material for board manufacture include the following: (1) Waste veneer, cores, and clippings from the manufacture of plywood. (2) Slabs, edgings, and trim from lumber production. (3) Green and dry planer-mill shavings from lumber production. (4) Logs of little-used species or logging residues. (5) Sawdust, shavings, and whole-wood scrap from millwork production. (6) Scrap from furniture manufacture. -
