Attic – Insulation


Old insulation was some sort of cellulose powder. Not particularly good and very dusty.

The layer of R11 on top of it was definitely not good enough for Colorado.

I removed all of it, bagged everything and vacuumed.

Added some nice R15 / R19 between the joist and about thirty OSB boards so I could walk everywhere.

Finally, added a second layer of R30 insulation on top of everything. VoilĂ !
