Laminated Veneer Lumber Density

High density and absence of cracks prevent from fire propagation and thermal effects inside the material.
Laminated veneer lumber density. Plywood was no option because it is not available in a length of 7 2 meters. Laminated veneer lumber lvl is an engineered wood product that uses multiple layers of thin wood assembled with adhesives it is typically used for headers beams rimboard and edge forming material lvl offers several advantages over typical milled lumber. This study was planned as a laboratory work for non structural purpose. Laminated veneer lumber lvl is a high strength engineered wood product used primarily for structural applications.
Wood defects are randomized. Floor beams dimensions 110 350 mm are made of laminated timber class gl 28. Much like plywood thin sheets of wood are sandwiched and bound with super strong glue. Unlike plywood microllam and other lvls are solid heavy and intended to carry loads.
Laminated veneer lumber lvl like glulam lvl uses continuous lamina lamina are sheets of veneer rather than lumber in glulam lamina thickness 1 5 6 mm 0 06 0 25 ins density that of its veneers dimensions those of standard lumber benefits compared to lumber. Lvl laminated veneer lumber. Engineered wood also called mass timber composite wood man made wood or manufactured board includes a range of derivative wood products which are manufactured by binding or fixing the strands particles fibres or veneers or boards of wood together with adhesives or other methods of fixation to form composite material the panels vary in size but can range upwards of 64 by 8 feet 19 5. Abdullah cemil ilçe the purpose of this study was to determine the best laminated veneer lumber lvl in terms of the density modulus of rupture mor and elasticity moe.
About laminated veneer lumber lvl as mentioned the generic name for this type of lumber are the initials lvl. Mechanical properties of laminated veneer lumber made from ash and red pine woods. Made in a factory under controlled specifications it is stronger straighter and more uniform. Lvl test results demonstrate the ability of the material to maintain its properties within 30 60 minutes at 300 c.
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 and pressure. Density 510 kg m 3 density 440 kg m 3 beams joists studs formwork lvl 48 p. Moreover kerto q has a higher flexural stiffness than plywood in the main direction parallel floor beams. For the floor plate a laminated veneer lumber is chosen.
Under the specified temperature the beam undergoes slow charring at the rate of 0 6 mm min. Kerto is incredibly strong and dimensionally stable. Structural composite lumber scl which includes laminated veneer lumber lvl parallel strand lumber psl laminated strand lumber lsl and oriented strand lumber osl is a family of engineered wood products created by layering dried and graded wood veneers strands or flakes with moisture resistant adhesive into blocks of material known as.
