Orange Crystals On Wood In Attic

I am guessing it is a preservative but all the literature says that the copper preservatives are green in color and these are definitely bright golden copper color and the only references to preservatives that use particles say they are much smaller in size than these.

Orange crystals on wood in attic.

Orange things on attic wood. As with all other types of mold orange mold grows wherever there is moisture heat and a food source however orange mold differs from other types because it is more likely to grow on wood than other organic materials. It s sap crystals that have been extruded from the wood due to high attic temperatures. There are on some but not all of the beams.

I will try to post a photo of this for your review. Just tree sap mostly from the heat in the attic. I hope this helps. Does anyone know what these orange things are on the attic wooden beams.

Email save comment 5. There is also another substance that this could be which is not mold it s sap crystals that have been extruded from the wood due to high attic temperatures. Apply pressure and gently chip away at the sap until the crystals begin to pop off. We see more of this sap staining when the wood used for framing was not kiln dried before construction.

Sap in painted wood will cause staining but it is ok in the attic. What causes orange mold. There are these tiny crystals about half a millimeter all over the wood in the attic.
