Wood products from responsible sources are a good choice for most green building projects – both new construction and renovations. Wood grows naturally using energy from the sun, is renewable, sustainable and recyclable.
Low Carbon Footprint
Wood has many attributes that make it an obvious choice for green building. It grows naturally, using energy from the sun, and is the only major building material that’s renewable and sustainable over the long term. It also outperforms steel and concrete when compared using life cycle assessment (LCA) methodology.
Forest Certification Plans
Chain of Custody certification tracks the certified material through the production process – from the forest to the consumer, including all successive stages of processing, transformation, manufacturing and distribution. It provides evidence that certified material in a certified product originates from certified forests. We supply products certified by the PEFC, SFI and FSC certifications.
Frequently Asked Questions
What makes the lumber blue?
Blue stain is a common cause for the discoloration of lumber. Certain dark-colored microscopic fungi cause a bluish or grayish discoloration in the sapwood of the tree. However, not all blue stains are blue. Common stain shades can be blue to bluish black or gray to brown. Sometimes, the stain coloration in lumber may appear as red, yellow, orange, or purple.
Does it affect the strength properties?
Blue stain has no effect on the performance and strength of lumber. Structural lumber is not downgraded due to the presence of blue stain and should not be labeled inferior lumber.
Where can blue-stained lumber be used?
Because blue stain does not detract from the strength properties of dimension lumber, blue-stained lumber can be used for exactly the same purpose as non-stained lumber. Just be certain that the lumber has a grade mark accredited by the American Lumber Standard Committee (ALSC), which identifies the grade, moisture content, inspection service, species, and mill identification number.
What about health and safety concerns?
Blue stain poses no health risk, and blue-stained lumber is safe to handle. The same safety rules for using non-stained lumber apply to blue-stained lumber:
Wear eye protection and a dust mask when sawing or machining lumber.
Avoid prolonged inhalation of sawdust.
When the work is completed, wash areas of skin contact thoroughly before eating or drinking.
Wash clothing that accumulates sawdust separately from other household clothing and
Can stained lumber be pressure-treated?
Blue stain fungi have no effect on the treatability of Southern Pine lumber and stained lumber may be treated to guard against decay and termites.
