Comments (13)Good old fashioned 30# saturated felt with the proper flashings/drainage planes have been done for a very long time and has proven to be reliable and one of the "old school" methods that still works today. On many remodels and repairs of period homes where felt was used as an underlayment, it's remarkable the condition it's in after all them years. Many new techniques have come out to replace and better older methods, but felt as an underlayment isn't one of them, imo....See MoreCedar over Tyvek- do we need a rain screen?
Comments (30)Ren, curious why you dont recommend plywood for furring strips. Its probably the most commonly used and proven material in my research and experience. Ive also got questions regarding your subsill details. I know this is a traditional look and detail but not sure how much increased bulk water resistance it adds with flanged windows. To me it seems the pictured subsill would still rely on caulk between the top of the subsill and bottom of the window frame/cladding. Unless you are completely removing the bottom flange (or not installing it for some brands) and extending the subsill underneath the whole window? This does not appear to be the case and it looks like the "subsill" is merely a piece of trim with its back butting into the bottom flange? These details are dealing only with the surface water, which is the biggest concern. Still, water can eventually make it through the corners and/or seal between glass and frame which is why its important to build the slope into the rough framing, and flash it in a way that directs water out onto the WRB....See MoreHuber Advantech Zip Sytem: affordable?
Comments (2)I used it on my build. If I remember correcty the cost was around 1000-1500 more than regular osb (1800 sf). I liked it because it was dried in (mostly) when installed. My builder liked it because it's easier than tyvek. My roofer didn't care as he used tar paper anyway. My mason had not seen it before but he put the brick on without additional house wrap (except at rim joist). If you put siding on, it supposedly helps prevent warping. If I were to do it again, I might not use the roof system if the roofer was lined up and ready to go....See MoreTyvek "DrainWrap vs. Tyvek "HomeWrap" with James Hardie Lap Siding
Comments (7)Ditto Worthy and JDS, Best would be 3/8-3/4" strapping with coravent or crafted insect screen at top and bottom. Any flat non-woven housewrap like 15# felt, standard tyvek or typar would be fine in that application if not using a WRB integrated structural sheathing like Huber Zip. If installers aren't comfortable with a true rainscreen strapping, then homeslicker would be next best followed by drainable housewraps. We've used 3d mesh like homeslicker behind shingles but not lap siding as I've read it can become wavy. Good job researching best siding practices. I don't think any siding should be installed flat against structural sheathing with standard housewraps in any climates except very dry. Non-insulated vinyl being an exception as it creates it's own rainscreen. Check out Matt Risinger's video to see a performance experiment between regular tyvek and stuccowrap. Speaking of which, I hope you are including exterior foam or similar performing wall details....See Moreobwannab
