Physical properties

Laser processing
LVL contains high percentages of phenol-formaldehyde adhesive (up to 10–12% by weight). Combustion fumes are significantly toxic: phenol and formaldehyde are released permanently. Cutting without certified HEPA+activated carbon extraction is strictly prohibited.
CO₂: LVL is technically cuttable with CO2 laser, but requires high power (typically 60W+ for thicknesses ≥4mm) due to the dense, void-free structure and the phenolic adhesive content. The cut edge is very clean and uniform with a distinctive dark brown line. Suitable for structural models where precision is paramount.
Diode: Not recommended. Even 20W+ diode lasers struggle to cut LVL at thicknesses ≥3mm due to the high density and phenolic content. Excessive dwell time increases the risk of carbonisation.
Fiber: Not applicable.
CNC / milling processing
Excellent for CNC milling. Excellent results for precision structural components, templates, cutting jigs, and reference squares. The laminar structure without knots or voids guarantees absolute repeatability of dimensions and a very uniform edge. Suitable for compression or helical bits.
Post-processing
Sanding: Very uniform surface without grain. Sanding grit 150 → 240 → 320. The edge, with visible layers, is an aesthetic feature that can be left exposed in designer furniture.
Primer: Not essential for edge finish, but recommended for surface faces if a uniform colour is desired.
Gluing: Good adhesion with epoxy and polyurethane adhesives. Sanding the surface with 120-grit sandpaper before gluing improves mechanical grip. The laminar surface can reduce PVA adhesion on some brands of LVL.
Seasoning: Stable and ready to use immediately. Store in a dry environment to prevent moisture absorption on the cut edges.
Over time: Excellent dimensional stability in any environment. LVL is engineered to remain stable with minimal expansion and no warping. Outdoors it degrades if not protected due to the phenolic content.
Common defects
- Higher cost than solid timber of equivalent cross-section
- Availability limited to beam formats — difficult to source as panels
- Industrial aesthetic (visible plies in cross-section) not always suitable for decorative uses
Safety
Recommended PPE: mask_p3, eye_protection
High-risk material for laser cutting: fumes are toxic (phenol, formaldehyde). Recommended only for those with certified extraction systems. Mechanical processing dust is moderately carcinogenic; always use an FFP3 mask with any machining.
Availability and formats
Commercial formats: beams 45–300mm, LVL panels 27–75mm, lengths up to 12–20m
