Attic insulation/remodel question
I have an old English bungalow from the 1950's in Chicago. The attic is finished and doesn't have enough insulation. So its pretty hot in the summer and cold in winters, boosting my energy bills higher. Here are the list of things we like to do:
1) Get blown in cellulose insulation with estimated R-value of R49, R55 before settling.
2) The attic currently has wood paneling and my wife and I don't like it and like to replace the wood paneling with drywall.
3) We also want to expand the attic in future (2-3 years as we can't afford it now) by adding shed dormers along the length of the house.
Now my confusion is what is the order we need to get these things done in order to minimize or eliminate wastage of work. Please help us decide. Thanks!!
