Additionally, we look at how to install an LVL beam. We explain how to determine beam size and also discuss their cost. In this article, we’ll identify what LVL beams are, their different sizes, how far they can span, and their different uses. Depending on its width, depth, and load parameters, an LVL beam can span up to 80-feet. The layers are heated, glued, and pressed together in different widths or thicknesses, and then cut to depths to meet various load requirements. After explaining what it was and the LVL beam span, I decided to give it a try, but I also wanted more information.Īn LVL or laminated veneer lumber beam is made up of thin layers of wood veneer similar to plywood. Such was a recent experience when I was looking for a beam for a renovation project. They would like to keep the roof over their families head and not laying in bed beside them.Every time I wander through my local lumber store, I seem to encounter a new product, not that it’s all that new, just to my awareness or my location. Good luck with the project but take the advice seriously as this isn't something to play with. Leave your footing open or dig down beside the newly poured area to verify the depth needed in your area for frost line and bearing etc.

Block out the floor and then add into your walls, fasten the LVL's to the existing framing and then refer to the code book on how to ensure all your collar ties and wind bracing are installed per code and then give your inspector a shout. So go get LVL's and determine your load points either side, go down in the crawlspace or basement and set up footings and posts/columns. 'hence why you should ensure your insurance is paid up' How I know that is that if a structural engineer gives you any advice whether spoken or written although it is a he said she said battle, it can potentially land that friend in court if the job failed. I'm with the other guys in that if you had a structural engineer friend he certainly wouldn't recommend the 2x12's nor would he suggest a truss built within the attic without a design stamp or some kind of paperwork covering it. I use this as I would rather be a little over in my math than a little under because a little under can cost a little over the budget. I am working on 3x11-7/8' LVL or double 14' to carry the load just going off of GP's charts for what you would use to span the outside wall for a garage door. I surely hated to tell the homeowner that well it looks good but certainly won't pass the inspection that the inspector will do after I pull the permits. Good luck.įunny as I just took over a project by a so called contractor, I walked in the living room and first thing I saw was an 18' wall removed and 2 - 2x12x18 clearing the 16'9 span. Roofs in the south are engineered to be flimsier than roofs up north. There are all kinds of loads to calculate, snow loads being one of them. Your defense is that you did it 'by the book.' Also, you don't say where the project is.

Even if there is a small crack on a different wall from, say, water intrusion, the homeowners are likely to point the finger at you. However, you must bring a structural engineer into the discussion and have him design a system that will ensure you are not liable for any problems down the road. So that would be a good strategy to approach your project. It is a bearing wall, but the braces almost act like trusses in a half-axxed way, that may explain why you are not seeing headers above the 48' openings. possibly posts sitting directly on the foundation or new footings in the basement. Also, each end of the beam would have to rest on established bearing, i.e. Undoubtedly more than a few purlin braces would have to be re-arranged. A guy could run an 18' LVL or equivalent through one end of the gable or hip and hang the ceiling joists from it.
