Intus Eforte mounting brackets

Question for anyone with experience installing Intus Eforte windows: The brackets I received with my Intus windows seem too wide. There should be a pic attached showing a bracket sitting in front of the track it is supposed to twist into. Online images depict a different type of bracket. All mounting instructions depict brackets with teeth that are only slightly wider than the mounting track. Did I get a batch that belongs with a different window type or something?

Thanks for any help.

Vapor barrier inside double stud wall — is this OK?

I’m building an energy efficient house this spring 25 miles Northwest of Minneapolis in the upper portion of zone 6. My wall design plan since the ’80s has been a double 2x4 stud with the vapor/air barrier in the gap between the two walls. This is similar to Joe Lstiburek's Ideal Double-Stud Wall Design with 2 taped layers of 1.5” Foil Faced Polyisocyanurate foam board replacing the ½” OSB in Joe’s design. I believe this design would keep the inside polyiso vapor barrier well above dew point under the most demanding winter conditions.

Insulating a block building from the inside

I have read all i could find on insulating a block building. It seems the best method would be to add foam to the outside. Unfortunately this is not in the budget for this project. The only mention of interior insulation seemed to be adding spray foam. The main building for this project is a two story from the 1930s with two later single story additions. Currently the inside has been completely gutted, while we hope to keep the outside intact.

Soil gas pipe capped in basement?

The is a soil gas pipe capped about a couple of feet from the ground in my basement. I'm looking at finishing my basement and am wondering if this needs to be vented to the outside or if I can go ahead and drywall over it. Why did the builders cap it?

Balanced ventilation year round when windows are closed?

I want balanced fresh air exchange to improve indoor air quality and reduce humidity in the winter. And also to improve indoor air quality and reduce humidity in the summer. It seems like hrv/erv are designed for only cold or only hot humid climates not a mix of the two.

Sanity check on very preliminary rough estimates of heating energy usage

Hi to the Forum. A few months back we bought a home in zone 5 (Northern Nevada at 5000') that was solely heated with electricity. We intend to install hydronic heating throughout and want to do it right. I was going to do a BEopt calculation but the computer I downloaded that software to was damaged and is currently out for repairs and bringing my heating upgrade project to a standstill.

Incorrect plumbing joint fix for basement bathroom install

5 years ago we had our main sewer line replaced with PVC line which 90s into our main 4" stack. City and plumber failed to put in a 90 y / floor drain and we we're told we would be fine with basement bathroom install. More recently, the driveway has been redone. Present day, 2 plumbers have told us that due to proximity of the joint to the wall, they cannot guarantee cracking will not happen on the short run of 4" that goes out the straight out from the 90. There is an 8" fail-safe as the pipe is under the foundation.

What direction should I go with my new/used home?

I purchased a 23 year old home to accommodate my growing family. It was constructed with double wall construction, wood foundation, Envirovent system etc. We live on Nantucket Island.
I am planning to install a mini split system and have questions on further improvements, possibly solar, that are upcoming.
My first inclination was to update systems based on the recommendations of local hvac contractors until I realized that my new home is unique and that I might need specialized consultation from someone more familiar with this "type" of home.
Any advice or suggestions are welcomed.

Polyiso foamboard (foil-faced on both sides) used in unconditioned space

Hello All,

I live in Portland,OR climate zone 4 & 5 marine.
I consider it mainly a heating climate and lots of rain.

I have a cape cod style house with 13/12 pitch roof on the main roof.
I have three gable dormers on the front, two new ones and one existing all with 20/12 roof pitch.
I just had ridge vents installed on the main roof and all three gable dormers.

I have managed to keep my new HVAC ducts in the floor joists and the are only exposed in the knee wall area before to going down into the (conditioned) floor/ceiling joists on the way to each room.
