Gap between drywall and floor

Hi there, I'm remodeling my home out in Austin, where the insulation was removed to address pest and mold issues. I'm looking to put new drywall up, but I wanted to know if it was possible not to have a gap between the drywall and the floor as my preference is to not use trim on this project. The drywall was mainly removed along the exterior walls, up to the 4' high mark, and sometimes 8' tall sections were taken down.

Creating ICF / Foxblock-style Footing Using EPS Sheets + Rebar

Greetings everyone -

I am trying to figure out an economical ICF design using 4x8 sheets of EPS rather than expensive manufactured ICFs.

After some hunting, I came across a product called the foothold, but they only make them 20" wide. Could be useful for folks building ICF walls or other alternative methods: http://thefootholdicf.com

PERSIST technique

With this design (Persist) combined with a cathedral ceiling with exposed rafters & exposed bottom roof deck. I don't have spacing of rafters yet but lets say they are spaced at 36" or 48" on center with the exposed rafters being 3"X 8" x 17' in size.

My question is what options do I have for attaching both the insulation & the furring strips on the roof
being rafters are spaced so wide.

A short recap,of progress for those who asked to see this house. Poured last piling on 6/2/2018
THANK GOD that step is finished handled to many 80 pounds bags of concrete by myself. twice.

Why did the beam at the top of my cathedral ceiling just start sweating after 5 years?

This spring the beam at the top of my cathedral celing just started sweating after 5 years of being dry all year. It started about a month or 2 ago,~ April.
The beam is actually a box beam covering an LVL. The roof, walls & gable end are insulated with open cell foam. The ceiling doesn't get wet only the beam.
No water entering during rain storms. We've never had a moisture problem actually we use a humidifier in the winter. We have a hot air geothermal heating system so the humidifier in the system can't maintain the correct moisture level.

Chimney downdrafting

I have a 1940’s home that is insulated well with new windows, and we find we get a pretty strong downdraft down the chimney when it rains or there is a pressure disturbance. I’m sure the flue door isn’t that great but there is a aluminum cap on top.

I’ve been keeping a window cracked in the hopes it pulls air from there instead although now in the summer that doesn’t seem like a great idea. I’ve seen balloons you inflate but I can’t imagine those defy physics of air pressure and temperature drops.

Metal roof on uneven strapping / purlins

My simple gable roof is built with trusses covered by OSB then underlayment then 2x4 strapping/purlins. The top chords of some of the trusses seem to be slightly bowed, because if I lay a straightedge from peak to eave, along some of those lines one or more of the purlins is up to 1/2" higher than the others. The roof has a 4:12 pitch and covers a 20' width and 48' length.

To install Classic Rib exposed-fastener panels, how much variation in the purlin height is tolerable?
