Fiberglass is fiberglass, cellulose is cellulose, just depends what color you like!
I'm assuming your looking at blow in, by far the easiest method. Doing it your self the cellulose is not as bad to work with, dusty but all that fiberglass fibers is something I would avoid.
As far as the unit, we know nothing about what you have, check with the manufacturer!
So, I have an older A-Frame that I am trying to upgrade and part of the process includes replacing the insulation in exterior walls. One of the problems that I have is that the studs are unevenly spaced but they generally trend between 20 - 22.5 inches. I am having a hard time finding 23" wide insulation for 2x4 walls unless I want to drop a lot more money then I need to fill the insulation in the wall space available. I have thought of two options to avoid said expense:
1. Buy 15" wide insulation which is plentiful and install them next to each other. I understand that this is not ideal given the risk that it might create a void that would not otherwise be there, but is it really an insulation killer?
2. Given that the rooms are not really big, would it be nuts to add faux-studs in between the existing studs to make the width for insulation less, thus making it easier to use the 15" width insulation? As noted, as an A frame most of the external walls are not super tall so it would not take a ton of 2x4's to do the trick (particularly in the main room where most of the problems are, which is cathedral style). Setting aside the time to do this, which would be minimal given that I am doing it over the next few months, are there notable problems with such an approach?
Thanks for any thoughts
PS. I understand that the best option is to pay the extra money, get the proper fitting insulation, and install it. I am just looking for feedback on options 1 and 2.Read More
I have to replace some insulation in an attic. The bays vary...some of the width are 12.5, 13.5, 14, 14.25, 14.5 14.75 and finally 15. Most are in the 14-14.5 range.
At what point should I trim the edges to fit the 15" batt width? i.e if the width is 14.5" should I attempt to trim off the 1/2"? It would be easy to do as I have the equipment and table....just wondering if the small amount of scrunching is something to be concerned about?
Thanks!
