Rhode Island remodel

My wife and I are in the process of purchasing an 1100 sq ft 1978 ranch in western RI (zone 5A). The existing house sits on an ~800 sq ft unfinished basement with the western (24') and northern (36') walls above grade/walk out.

Our plan is to finish the basement at the kitchen/living areas and re-model what will then be the 2nd floor as 3 beds, 2 baths, a laundry and a study.

Help building a green house or a self sustainable home

I'd like to build my own home or at least design it. But I'd like to know what I'm talking about -- rather not stick my foot in my mouth. I tried to find a contractor but had no luck. They are all out for the money, said I can't build anything less then 200K and that's for cheap materials.

Any help would be awesome. Thank you.

Critique this approach to insulating and heating, please

I was hoping to get some input on the attached plans, with regard to the building envelope and best approach to heating/cooling.I am building in Morris County, NJ. zone 5a
I like the philosophy of building the tightest envelope and keeping the heating/cooling loads low.I plan on doing a blower door test after framing and before the window/door sheathing is removed for maximum tightness.

Is blown mineral wool in crawl space harmul?

Had wool-like insulation blown in roof crawl space 30+ years ago. Wool insulation has found it's way into ventilation system causing excessive dust in house. Is the insulation harmful? What will mitigate the dust. Had ductwork cleaning a few years ago but return system has been infiltrated with insulation. Should visible insulation be removed to help with oily dust.

Why is there no plywood sheathing shown in your window installation construction details?

Hi all,

I was looking through the "How to Install Windows Right: Details for Leak-Free Windows and Siding" and didn't see plywood or OSB sheathing under the rigid foam sheathing in the drawings. What am I missing?

Thanks in advance,

Should I fill up unvented soffits with cellulose or block them off?

Hi all, I have a c. 1915 house with two gable vents. Until about a month ago, the attic had no access. I installed an access and have been busting my butt getting rid of the knob and tube wiring so that I can insulate. My ultimate goal is 18" of insulation, r-60 i believe. My climate zone is the zone four, but one county to the north is zone five.

Now, to my questions...

Cracks in an airtight drywall approach

Hello - I installed drywall in my cabin last summer without any poly vapor barrier, following the fundamentals of the airtight drywall approach. Over the winter, fine cracks appeared at some of the drywall seams. This appears to be a common issue with unheated cabins experiencing large swings in temperature & moisture. Now that my air barrier has been compromised I'm not sure what I can do. Repairing the cracks seems futile unless I can provide a heat source during the coldest months.

Any suggestions?

Thanks for your help,

Who do I contact or is analysis done here?

I have a new construction house that is designed and ready to be built.

I am satisfied with the layout, but need expert analysis on choosing the insulation and HVAC strategy.

I want someone to look specifically at my plans and advise me on this particular project. I am unsatisfied with the "spray foam seems to work well, or i sell a bunch of...." responses that I am getting.

Who performs this type of service? How do i find someone reputable?
Do I just upload plans here in another post?

I live in Northern NJ zone 5A.

Thank you for your help
