Brick house insulation

Hello,

My situation: I have a brick house, that initially had plaster and lathe walls. With the floor joists supported by inner wythe, and the joist ends embedded in the brick. I removed the plaster and restudded the walls with 2x4s.

My concern: On the lower floor, I insulated the stud bays with batt insulation. I thought this was a good thing, however, after reading your article I think I may have been mistaken.  I am beginning work on the second story and don't want to make matters worse.

Boral--Proper installation on vertical siding

We are building an addition in Western Pennsylvania. The plans called for cedar siding but a change order now specifies Boral Bevel siding installed vertically over 1/2 inch plywood +Tyvek House Wrap + 1 inch XPS T/G foam insulation on the outside. All the Boral literature indicates installing vertical siding on horizontal drainable furring like CoraVent. The architect talked to the Boral rep and she stated that it was OK to install directly on the wall without furring because Boral won't swell or rot. Any suggestions?

Estimate kWh electricity needed to heat new addition?

I am planning to expand an existing room in my house. The room is currently on a separate heating zone (oil heat, forced hot water). I have solar panels and generate an average 1700 kWh electricity per year more than I use (this is a 3 year average). So I am thinking of heating the remodeled room with electric baseboard, hoping that I can essentially heat it for free with the excess kilowatts that I generate. But I would like to project how much electricity will be required before making a decision. Can this be estimated?

The room will be 13' x 17' (221 square feet).

2-inch foam on the interior face of the wall: What are my electrical box options?

Due to a foundation snaffu, it looks like I will have to move my 2in. EPS foam to the inside of the wall assembly. Although that seems feasible, it will add some labour and material cost (3/4" strapping everywhere, 3/4" plywood for the kitchen/cabinet area etc.)

I was specifically looking at the extra pain involved in installing electrical boxes. It seems most of the box extension rings I could find are limited to 1.5", which is a bit shy of the 2in. I would require.

How important when insulating with foam board is it to be for the joints be overlapped, or pieces be foamed in place?

My project is a retrofit of foam over the sheathing of a geodesic dome. Every triangle has a gentle angle, which will interrupt the five inches of XPS foam that's being added. The sheathing below the foam will be primed with an acrylic sealer and taped. Over the insulation will be a water barrier, and strapping, 2 3/8 inch vent space, sheathing - with Densdeck Prime (sealed and taped) and a single ply adhered roofing of TPO.

Chimney chase condensation

Hello All,
Classic problem I believe.

I have a wood framed chimney chase which houses two 8" insulated, stainless steel metalbestos wood stove pipes and my main DWV stack. On certain days, when the inside/ outside temps, and the relative humidity are just right, I have condensation build-up and dripping from the underside of my chimney chase roof.
Construction detail:

Roof:
6x10 timber rafters 36" (on center)
2 x 6 rough sawn decking (not T&G)
Grace Tri-Flex
3 layers of 3" Polyiso foam board
2x6 Sleepers 36" (on center, screwed to rafters below)
3/4" T&G OSB decking

In Md. I have a vapor barrier and I want to insulate and finish basement

What is the best way to finish the basement. I already paid for drainage system; vapor barrier is up on walls. What is the best type of installation...? Basement is framed 24' vs 16. This is so frustrating for me, my brother gave me R19 that he had left over but I don't think I can use it. Someone told me not to use paperback fiberglass near vapor barrier...Help!
