Langboard manufactures Industrial Grade products to meet your specific industrial needs. We were the first OSB manufacturer in the extreme southeast United States. We have recently added a new production line and press that allows us tremendous flexibility in producing specialty products.
Structural panels such as OSB using exterior type phenol formaldehyde and isocyanate resins do not require certification for formaldehyde emissions. Isocyanate resin panels do not contain formaldehyde so no risk of formaldehyde emissions exists. Phenolic-based adhesives are specifically exempted in Section II.C.3 of HUD Rule 24 CFR 3280 (of the August 9, 1984 Federal Register), which states that HUD “has decided to exempt products that are formulated exclusively with phenol formaldehyde resins and surface finishes from the testing and certification provision of the rule.” The amount of formaldehyde emitted from panels using phenolic-based adhesives is considered too small to be significant and has therefore been exempted. Isocyanate resin panels do not contain formaldehyde so no risk of formaldehyde emissions exists.
