I know these may be stupid questions but hopefully someone more enlightened than me can answer this.
I am preparing a workshop in an unfinished area of my basement. It appears the previous owner framed a room but never drywalled it. Before I drywall it I wanted to add insulation between the studs but wanted to see if that was ok to do considering the wall has some form of insulation with a tin foil type backer already applied to the concrete walls. Is it ok to just apply regular insulation between the studs effectively doubling up the insulation?
Secondly, since it doesn't appear this room was framed during construction and was done by the previous owner can anyone advise if the green tinted board in the picture is actually pressure treated and ok to be used as a base plate? If it is not I rather change it out now before dry walling. I only ask because all pressure treated lumber I have seen has a brown tint and I have not seen one like this with green tinting. The rest of the base plates in the room are brown except this one wall.
Thought? Thanks in advance.
