Black Attic Insulation

What does this mean.

Black attic insulation.

We love our diyers so take up our incentive to improve your attic insulation situation yourself. The area in the attic that has turned black is right under the gable vent. If your attic or wall insulation is in batt or blanket form whether it s fiberglass cellulose or another material you generally don t have to be concerned about asbestos. Over the years that continuous air leaking from the house up to the attic turns the fiberglass black with dust.

So any place you see black fiberglass dig down and look for where the air is coming from. The black color is not the color of the insulation. The last pic you posted is loose fill rock wool so i d imagine that the blanket material in question is the same. Is this mineral wool.

The types of insulation that were most commonly made with asbestos are loose fill also called blown in insulation. You get a free blown in machine rental with your insulation purchase. I see small blotches of gray insulation throughout the blanket which indicates that this insulation is black coated due to serious venting issues within the attic. We have a 1960 s ranch in columbus oh where i opened up our soffit to find this black faced barrier made by forty eight insulations that has loose fill fiberglass insulation on top of it as our attic insulation.

The reason the fiberglass gets discolored is that it s acting like an air filter. The black facing is paper like. The area is over 2 bedrooms no moisture coming from below. Walls that are improperly insulated may develop mold because they will absorb moisture from outside.

Blown in insulation is installed using blowing machines. The vent is just above the area in the picture. Get a free 24 hour blown in machine. The 2 gable vents are the only venting.
