Would Tyvek on top of rafters and under roof sheeeting meet R806.4 for non-vented attics?

Wish to have a non-vented attic but desire blown insulation. It appears R806.4 does not allow this. Would Tyvek remove requirement for spray insulation against roof sheeting?

Liability insurance - what would that cover?

1. Does liability insurance cover issues related to removing improperly installed open-cell foam in an attic on the underside of a roof (i.e. all those horror stories about roof rot, or open-cell continually off-gassing or smelling weeks after it was installed, etc..)? Or is that a different type of insurance?

2. Should I specifically ask for the details in the Liability insurance to find out specifically what it covers, is that something contractors should be willing to share?

How do I fix the high air exchange in my straw-bale home?

Two years ago, I purchsed a straw bale home in Minnesota. When I closed the house was in poor shape and the exterior had to be rebuilt. Our first winter in the house was cool and drafty and we were spending a fair amount on heat. We did as much research as we could, but we have struggled to figure out how to fix and maintain our home.

Fresh air intake filters


I have the RecoupAerator ERV that I am in the process of getting installed. I have some sheet metal/duct people coming next week to give me estimates on installing the fresh air intake duct that will terminate thru an exterior soffit.

The RecoupAerator comes with MERV 12 filtration material inside, but I am wondering how to filter the air at the entry point into the fresh air intake duct. A simple insect screen there might still let small bugs and such into the the duct work where they will decompose.

Best time to stop construction for winter..?

It looks like our builder has overbooked himself and will very likely not be able to put the house under the roof+finish exterior before winter. We understand that one could continue to work in winter, through all stages of construction if additional measures like heating tents are used when applying exterior EIFS stucco. So the problem here has to do with management of resources and time rather than the physical limitations. Nevertheless, we face these choices:
1) don't start until next spring (bank funding would be lost and we'd have to re-apply)

The joys of insulating...

What is the best way to insulate around the corners of rigid round duct using foil-faced blanket type duct insulation?

Make a "sock" and coax it around the corners and don't worry about bunching?

Snip out pieces and try to form something like an elbow while generally making a mess and wasting time?

Something else?

Woodpeckers, Stucco + Exterior Foam with Rainscreen

Our client has requested to change the exterior wall cladding from from smooth panel cement board to acrylic stucco mainly for aesthetic reasons (eliminates corner trims, battens, etc.). Woodpeckers are a real concern in the area and when they knock on stucco with foam behind it sounds hollow so they keep digging.

First up, the proposed wall assembly: (BC Interior Climate Zone 6)

5/8" GWB
Membain vapour retarder
2x6" Studs @ 24" of
R22 Fiberglass Batt Insulation
3/8" OSB Sheathing
Tyvek WRB
2 Layers of 1" Type 2 EPS with staggered joints and taped seams on outside layer
