ZIP Window Detail with Exterior Insulation

On ZIP's website, they have window details which appear to combine the flashing/window buck of an outie window, but it is shown flashing into a WRB (in this case the ZIP sheathing) located behind the exterior insulation.

New house build, SIPs?

New member here, we are planning to build a new house this summer and I'm exploring my options for wall systems. I plan to do the framing myself. House will be roughly 2500 sqft in Ottawa, Ontario Canada. Not the coldest place to build but not far off, and just for kicks it gets pretty hot and fairly humid here in summer as well.

Florida Shed With A/C, Insulation, Vapor Barrier - Please help!

We are planning to buy a 12 x 24 pre-fab portable building like the Lofted Barn at Cookstuff.com.

We live in southwest Florida and need to air condition it 365/yr (pretty much). Going to use the building for our handmade soap workshop and humidity is very important to our soap curing process so we will be using a portable dehumidifier in the space in addition to a wall a/c.

air sealing and insulating upto chimney?

Hi guys!

I'm looking for some advice on insulating and air sealing near a fireplace and chimney in my house (zone 6a). The chimney is unlined and the furnace and water heater are vented up chimney. I'm not going to use the fireplace as is, but I'm planning to put in a wood burning stove insert at a later time. Looking at the attached pictures, do you have ideas on how to air seal the space between the right of the chimney and the framing. Can I fill this space with mineral wool insulation? For the rest of the house I used mineral wool with membrain. Thanks, I appreciate any help!

Installation of a firebox in a very old stone fireplace that is on an external stone wall and is very damp.

Do I install a vapour barrier first and then rock wool or ceramic wool with aluminium foil in order to insulate the interior of the existing fireplace? would I use similar techniques to the techniques of shower construction e.g.. backboard etc?
