It is typically used for headers, beams, rim board, and edge-forming material. LVL beam (Laminated veneer lumber) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. How much does it cost to install a LVL beam.How do I determine what size LVL beam I need?.What is an LVL beam:- Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. LVL is product of recent innovation they are result of new technology and economic pressure to make use of new wood species and smaller trees that cannot be used to make solid Lumber. The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (Glulam). LVL beam: Sizes, Cost, Span, Calculator and price It is available in a wide range of lengths, widths and thicknesses. It is typically used for boards of all kinds, for headers, beam rim boards, skateboards, as well as beams, trusses, edge forming materials and more. It is a high-strength structural engineered wood product of recent innovation and one of the most widely used kinds of lumber in construction projects in. How does a blind header attach to the existing joist and still support the weight of the wall? Even if I could reduce these headers by six inches, it would be fantastic.Laminated veneer lumber or LVL is much look like plywood, generally made of thin sheets of wood which are sandwiched and bound with super stronger glue. Manhattan42 - I'm curious about the blind header. He is using an LVL-LAM beam (a double 2x12 that is spanning 12 feet. We had asked our contractor about using steel and he said that it flexes more than the engineered product. Sue36 - It will look like a beam, and there will be two intersecting each other. Posted by missmuffet (My Page) on Sun, Sep 19, 10 at 9:12 See if it is possible for your builder to use this technique. The result is a flush ceiling or a much less pronounced projection of the header below ceiling level. Rather than support the joists under the ceiling, the joists are attached to it. One way to reduce the header projection below the ceiling or to eliminate it altogether is to build what is called a 'blind header'.Ī 'blind header' is built right up into the ceiling. If your headers are 12" below ceiling height, they will be 84".slightly above door opening height and well above minimum. Thats the same height as a doorway opening. Posted by manhattan42 (My Page) on Sun, Sep 19, 10 at 8:10Ĭode required minimum height under a header or beam is 6'8". You can used an engineered product or steel and the header will be smaller. Dimensional lumber results in a larger header. Headers should be engineered based on the load and the width of the opening. Is this going to look like a framed opening or just a beam hanging down? If a beam, I think it will look low. Posted by sue36 (My Page) on Sat, Sep 18, 10 at 23:52 RE: how low can a header go? please help clip this post email this post what is this? Can anyone give me an idea of what an acceptable height for a header would be? If my ceilings are only 8 foot and these things are another foot below that - am I crazy? Help. However, the headers look much lower than I imagined they would. Specifically, the contractor is putting in two headers to hold up the second floor of the house - good idea not to have the house drop in. So they have begun knocking down my supporting walls (yikes), and now I'm second guessing things. Here's my original post and some responses thus far: I posted this on the kitchen site (as that is where I've been hanging out lately), but was hoping that someone over here might be able to help.
