Engineered wood is environmentally friendly since its density and strength may match (or even outdo) those of old-growth timber while still using material from young trees. Additionally, waste is decreased since all of the trees are put to use, including flaws and offcuts from dimensional timber production. Due to its high density and layers of grain running in opposite directions, engineered wood may be more durable than dimensional timber.
Many people believe that engineered wood is less aesthetically appealing than natural wood because of the apparent wood strips (rather than the smooth, natural look of solid timbers), and this is the case for several reasons. The exception to this rule is glulam, that is used for constructing. Compared to the price of dimensional lumber, the cost of engineered wood, specifically LSL, is rather pricey.
Different Types Of Engineered Woods
Hardwoods and softwoods, like those used in lumber production, are often combined with other materials like adhesives to create engineered wood boards. Chemical or thermal techniques transform sawmill scraps into lumber that conforms to precise sizing specifications that are impossible to obtain. Construction, both residential and commercial, as well as industrial, make use of engineered wood.
Laminated Veneer Lumber
LVL is a high-density engineered wood product used in framing made of wood veneers compacted with resins and glues. Since the surfaces in LVL are layered with the grain all going the same way, the material is incredibly sturdy yet has a single-strength axis. There is a direct restriction on LVL loading.
Oriented Strand Board
Compressed wood sheeting is made by mixing wood strands or flakes with adhesives. Load-bearing flooring and roof decking benefit from its broad mat construction. Some OSB is sanded, while others are not; examples of the former are Advantech and Legacy premium subfloor. However, not all OSB boards are treated to withstand dampness. If there is any weather danger, only use the highest quality OSB.
Plywood
A sheet product made from thin layers (“plies”) of wood veneer pressed and adhered together. Plywood’s “cross-graining” quality gives dimensional stability. It keeps the panel’s strength uniform in all directions, which is only one of the many reasons they are so helpful to builders. Plywood, like any other wood, may expand and contract depending on the humidity in the air, so make sure to leave a space at either end.
Conclusion
In conclusion, engineered wood has both positive and negative aspects when used in residential construction. It’s good for the environment since it uses material from young trees and produces little waste. With its high density and layered grain structure, engineered wood may last longer than dimensional lumber. Engineered woods like plywood, oriented strand board (OSB), and laminated veneer lumber (LVL) all serve distinct functions in the building.
