Fill the stud cavity full, but don't try to stuff R19 insulation in a 2x4 stud wall.
I would try to close off the top with something solid to keep out the noise.
So measuring how I could, today going to try and get better measurements.. But from what I can tell I have 1" or less of clearance between the framing and bricks to slide any sheathing or panel in.. I was reading the hardi site lastnight and seems the thinnest OSB I can use is 7/16, so with that and the thickness of the hardi, I should be fine to install the OSB with little mods to the bricks or mortar to make everything fit in between.
Lastnight I was able to replace all the insulation with the R-13 I had to save a little money. I had just enough to do the entire window. And since I bought a roll of wrap, I put some up temporarily just because there is a slight chance of rain today. Ill be removing that and moving forward with the OSB layer next.
Will post pic of new insulation later.
Here is the updated setup now with the new R-13 insulation.. the old stuff that was in there was R-11, so little improvement.
Cant really see it, but the amount of space I have between the bricks and the framing SHOULD be enough to fit the OSB and hardi with slight persuasion.
Even if the hardi won't slip behind the brick, the trim will close it off.
True, so since I haven't started my wife and I have been discussing the material to use to give it a nicer look than before..
So of course the other option would be to use the hardi panels instead of the 4x8 sheet.
Obviously the panel would be easier to install and work with.. ;)
But after looking at a few examples of installing the siding panels, the trim would go on first and the panels with be placed within the opening between the trim pieces. Would that change how to install in our current setup?
Also, is nailing the boards by hand just as simple as wood? I was looking at nailers today and considering the cost, if I can do it by hand I will do that, may take longer, but saves me a couple hundred.
Well tonight after work, I got the 7/16 OSB installed on the sides since those were easy and could be done before the window. The rest will have to be installed tomorrow or Saturday when the new window goes in.
Well over the weekend got the trim done before the weather changed, so its ready for siding as the weather lets up.
Im pretty happy with how its turned out so far, such an improvement
Not seen in the pics since this was before the rain, I filled in all the bigger openings along the trim/brick areas with the spray insulation, also from the inside of the house, if the weather is bad after work, then going to finish up the inside, replacing the sheetrock and installing the corner bead so that its all ready for mudding.
So this weekend finished installing a replacement window, got all the trim done and ready for the hardi siding as the weather permits.. but before I continue while I can with little effort and since I have to redo the top trim above the window anyway wanted to make sure about the flashing..
So when I watch the videos ******, all the windows have the 1x3 or 1x4 already around the window and then they are installing the z-flashing, so I need to know, it makes sense that the flashing would go under the trim so that any water that makes it behind the trim hits the flashing and then over the window..
So since the window sticks out maybe 1/8 or slightly more than the trim, where should the flashing go?
Flashing goes underneath whatever is above it and over whatever is under it. If possible it should have a little slope to help push water to the outside but as long as it seals this isn't an absolute requirement. Configure the ends and corners to cause any water which gets in there to go where you want it to so that the weather-seal is maintained top-to-bottom and all water stays outside. Think like water and make the house keep you out.
