CLT vs LVL
Natural Material · grade comparison
CLT and LVL are both natural material grades. LVL is the stronger of the two: tensile strength 42 MPa (6.09 ksi) against 16 MPa (2.32 ksi) for CLT, about 163% more. In exchange, CLT is the more ductile: elongation 0.9% versus 0.8% for LVL. CLT is lighter (0.47 g/cm³ vs 0.55 g/cm³ for LVL) and LVL is stiffer (13.8 GPa vs 11 GPa). On the shop floor, LVL sits in a lower cost tier (budget, $) than CLT (standard, $$).
CLTChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
LVLChoose it when strength drives the design, or when cost is the deciding factor.
CLT vs LVL: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all natural material grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

CLT vs LVL — frequently asked
Is LVL stronger than CLT?
Yes. LVL has a typical tensile strength of 42 MPa (6.09 ksi) against 16 MPa (2.32 ksi) for CLT — about 163% more.
Which is cheaper, CLT or LVL?
LVL is the lower-cost material: it sits in the budget tier ($) while CLT is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, CLT or LVL?
CLT, by a small margin. Both rate excellent for machinability — 92/100 against 85/100 for LVL.
