New siding and housewrap
Hello, climate zone 5 (Boston Area) I removed cedar siding around my windows and I realized that a large portion of the plywood probably 1/4 of the entire wall is completely rotted and needs to be replaced with new sheathing (this will be done with 7/16″ ZIP). At this point I plan to take the rest of the siding down and put up all new siding (want to use LP Smartside). Unfortunately I won’t be able to put continues rigid on the outside due to no overhang, etc. This wall has a bunch of line-sets from my Mitsubishi heat pumps that are going to be a pain to side around so my questions are as follows:
1) Can I put the line-sets into the walls or will that create problems? I hate screwing the line-sets into the siding because I feel like its just creating another place for water to enter, unless there is a good way to flash or detail them? Everyone in my area that has heat-pumps has vinyl and I can’t find any good details on how it should be done with a hard siding.
2) Where the existing sheathing is still good, I was going to use Blueskin VP 100 to cover it and use Ben Obdyke Home Slicker as a rain screen BUT the local LP rep. said just going over the ZIP and plywood with HYDRO-GAP house wrap is sufficient. I think the Blueskin/Zip would at-least give me more energy efficiency by stopping the air leaks better. Any thoughts would be helpful.
