composite wood for rafters

Tutorial - American Wood Council

wood is naturally engineered to serve as a structural material: The stem of a tree is fastened to the earth at its base (foundation), supports the weight of its branches (column) and bends as it is loaded by the wind (cantilever beam). A complete analysis of wood's mechanical properties is complex, but understanding a few basics of lumber strength will allow you to size joists and rafters with the use of span tables. Let's start by taking a broad view. The structural goal of a house is to safely  【Get Price】

Composite Decking 101 - Popular Mechanics

3 Jan 2017 Thinking of replacing your wood deck with rot-resistant composite decking material? Read this first. People choose wood plastic composite (WPC) or even plastic lumber (PL) over wood because they want the finished project to resist rot, wood-eating insects, harsh sunlight, and mold and mildew, and they never want to paint it. So, do these Finally, most consumer-grade WPC and PL can't be used structurally, such as for joists or corner posts. for those you'll need  【Get Price】

Structural Composite Lumber (SCL) WoodSolutions

SCL can be used for a range of structural applications including beams, joists, studs, columns, rafters and I-Joist and I-Beam flanges. Laminated Veneer Lumber (LVL). LVL is the most common SCL product and is widely used in the Australian building and construction industry. LVL is a high-strength engineered wood product. It is comparable in strength to solid timber, concrete and steel and is manufactured by bonding together rotary peeled or sliced thin wood veneers under heat  【Get Price】

CHAPTER 5: Design of Wood Framing - HUD User

CHAPTER 5. Design of wood. Framing. 5.1 General. This chapter addresses elements of above-grade structural systems in residential construction. As discussed in Chapter 1, the residential construction material most commonly used above grade in the United States is light-frame wood; therefore, this chapter focuses on structural design that specifies standard dimension lumber and structural wood panels (i.e., plywood and oriented strand board sheathing). Design of the lateral force  【Get Price】

Structural Composite Lumber (SCL) - APA – The Engineered Wood

LVL is a widely used structural composite lumber product. It is produced by bonding thin wood veneers together in a large billet so that the grain of all veneers is parallel to the long direction. The LVL billet is then sawn to desired dimensions depending on the end-use application. Because LVL is made with scarfed or lapped jointed veneers, LVL is available in lengths far beyond conventional lumber lengths. Popular LVL applications include headers and beams, hip and valley rafters,  【Get Price】

What Type of Material to Use for Fascia Board? Hunker

30 May 2011 Most modern homes built with conventional lumber and either hand-cut or trussed rafters are fitted with fascia boards to cover the exposed rafter ends. The fascia protects the rafters from weather and potential decay while making the installation of gutters and down-spouts much easier. The exact composition of composite lumber varies by manufacturer, but it's usually made from a mix of recycled plastic, wood chips or sawdust and then bound with epoxy resin. 【Get Price】
