Inground gutters

A few years back I came across an article in Finehomebuiling about inground gutters. Has anyone tried this solution to wet basements? Does it work?

Trapped moisture on SIP roof

I knew SIPs were the Achilles heel of my 100% engineered house design, But because of inattention to detail, heavy rains at a critical time of my house build pushed water underneath the PVC membrane (applied on mechanically fastened DensDeck) onto my SIP. It happened the night before the adjacent wall could be spray foamed to properly seal off the membrane. Unfortunately, the spraying was later done to the walls and the underside of the SIPs without knowing there was water present.

Spaceloft my only option?

Needing to get all the R value I can get in a limited space. From the cob webs you can see that this is an old house. Recently installed Cedar shakes with felt underneath over the 2x4 studs or mini rafters...
I think they call this a skip sheathing install of the cedar roof?
So, 3.5" is all we have but we'd like to get to an R50 or thereabouts in our upgrade of this 1925 built home in Climate zone 4C.
Spaceloft seems the only option. With an R10 per inch. It comes in 10 cm thickness, 0.4".

Flush-mount exterior electrical boxes in board & batten with rigid foam and rainscreen?

Good evening all,
I'm still working thru issues involving board and batten over strapping and rigid foam. Now I'm looking into the exterior electrical boxes (for outlets and for lights).
I'd like the boxes to be flush-mounted, with the "rain screen" (do we still call it a rain screen if the strapping is horizontal?) space serving as a conduit chase. That would minimize penetrations of the insulation and WRB- while avoiding surface-mounted conduit.

Where's the smell coming from?

A musty, mildew smell emanates from 2 bedroom closets in the front of our single story 13± year old house every time it rains since we bought it 2 years ago (and before us no doubt)...but nowhere else in the house.

Unvented slanted roof with radiant cooling and NO polyurethane in 4C

We are in Everett WA, north of Seattle, right on the coast, zone 4C. I hope that our location will save us...
We have a low sloping steel, west facing roof. Double, 30 weight felt paper underneath to dampen rain noise. I presume 1/2" plywood sheathing. 2x12" rafters, 11" true depth.
We will install WarmBoard R (13/16" thick OSB with aluminum tracks) underneath the rafters for summer cooling and supplemental heating in winter.

Intus installation

I am considering Intus windows for a project happening soon due to their great U-value and high SHGC numbers. One thing I'm hung up on is how to install them with a 3/4" strapping rainscreen and exterior trim. The supplier said the window is installed at the sheathing layer then the rainscreen and trim are applied over that. That method seems to flash it well at the top but what about the water running down the face of the windows. There are also weep holes that need to stay open on the bottom making sill trim tricky.

Need input: House location on site, soil compaction, grade changes, retaining wall

I would like your input regarding the house location on my site plan (I am the owner).

My considerations:

1) Southern exposure vs. street angle so we oriented 15 degree from true south. I am happy about this decision and I think the landscape architect is capable to make the landscape work with this orientation.

2) Main unresolved challenge:

Flashing and trim details for doors and no-fin windows with board-and-batten siding over furring and exterior foam board

Hello GBA,
After looking thru a lot of details here, and at FHB and BSC, I haven't found one that's quite right for my situation yet, and I hope you can help me.
I have a garage that was made to look like a small barn (22' x 32', 2 stories, gambrel roof). It was built in the early 1990's, with 2 x 4's 16" on center, 1/2" OSB (plywood at the corners), no insulation, no WRB, and lap siding that seems like particle board with a stamped grain pattern.

Rainscreen design advice

Did a search on this and came up with nothing... The question centers on a rainscreen design for verticle cypress siding on rigid foam over CMU. Zone 2. Block house. One story.

Thinking 1" rigid foam then horizontal furring topped with a core vent type product then siding.

Interested if this is proper design, if core vent is over or under furring strip and how far apart to place furring strips. Install attaching furring strips over the foam to CMU via tapcons would be a heck of a lot easier with the vent on top of the strips.

Thanks for the time to answer.
