OTOH I will be spanning 12" in the ridge of the third bay (on the left in the image I posted earlier). But I'd be happy to use trusses if it saved money and did the same or better job than a built up LVL. And more importantly when physically linked to each other. The reason for the original question is that the span tables I've found for floor trusses don't show their capacity when stacked side by side. The headers will be in a 2圆 wall with a minimum of 2ft of space between the garage door rough opening and the base of the engineered I beam rafters (16 OC). So I am on my own ticket for designing and constructing a safe, cost effective structure that I want to work in and look at for the rest of my life The garage is in a rural part of the Texas Hill Country: no HOA, no snow load, no engineering stamp, no inspections - period. Glulam Garage Door Headers Offer Design Options, Form C410Ĭonnection details and installation recommendations for glulam in residential garage door framing.Sorry I forgot to provide location info. For the designer, the capability to achieve longer spans makes it easier to achieve the open, airy designs and high ceilings that are popular in today’s homes.Ĭontains span tables for glulam floor beams in residential construction, tables for substituting glulam for steel beams, and design details. In residential construction, the strength of glulam allows for long spans without intermediate supports in garage door headers, floor beams, and ridge beams. Glulam beams, arches, and trusses can be used in a host of design configurations. The strength and durability of glulam beams make them an ideal choice for large, open designs where long spans are required. These beams are also supplied in widths of 3 1/2" and 5 1/2" to match conventional 2 x 4 and 2 x 6 wall framing. Using IJC glulam makes it easy to frame floors flush, with no need for extra furring out. Because glulam columns are available in long lengths, the members don’t have to be spliced together, as is often necessary with sawn lumber.Īn I-joist compatible (or IJC) glulam beam is manufactured to match the depths of I-joists used in residential construction (9-1/2", 11-7/8", 14", and 16"). Glulam columns are straight and dimensionally true, making framing an easy task. Sloping glulam rafter beams are the perfect complement to ridge beams in exposed applications. They can span long distances and carry virtually any design load. The open, airy designs and high ceilings common in residential construction today make glulam the perfect choice for ridge beam applications. The strength properties of glulam headers, combined with their availability in common framing widths, makes them well-suited to these key structural applications. Glulam is an ideal choice for garage door headers and headers over both large and small window openings. The most versatile engineered wood product on the market.A sustainable product manufactured from a renewable resource.Dimensionally stable product that resists cupping and swelling.Excellent strength properties useful for value engineering.Inventoried locally in common framing sizes.Manufactured in I-joist compatible depths.Cost competitive with other engineered wood products. ![]() Using glulam in residential construction offers these advantages: Whether chosen for the beauty and aesthetic of natural wood grain, or for the ready availability and dependability of stock beams, glulam beams and columns are strong structural members that offer design flexibility and ease of installation. Glulam beams are used in both exposed installations, where appearance is important, and in many hidden structural applications, such as floor beams and headers.
