ceiling insulation

Have several questions.

1. I found a lot of rigid form( 2.5 inch ) in the ceiling which is laid over the cellulose insulation. I thought that the moisture will be kept under the foam. Do I need to take off all the rigid foam? or just leave it?

Why is there condensation on the return ducts and mold in the attic as well 60% humidity throughout the home?

This home has since been remodeled, including all new metal duct work and insulation. The issue that we need to resolve is the high humidity in the house at about 60-65% even though the unit is running efficiently. There is quite a bit of condensation on the return ducts in the attic as well. We have had two reputable Heating and Cooling Contractors come to assess the situation to no avail. The owner attempted to contact the original Mechanical contractor, but has not been able to speak to anyone yet.

Mfg. home, block skirt insulation

I am setting a 25x65 mfg home on a full slab foundation in zone 5+, high desert Cascades. I will be putting in a 3 course cement block "skirt" with mechanical ventilation. I am considering installing 2" rigid foam panels 24"x48" attached to the inside of the block skirt. I am looking for heat retention in the winter primarily (-20 on occasion). Will this be worth the effort and expense??

How to insulate rim joists & above grade basement walls in older home without using foam?

I'd appreciate input on how best to insulate/air seal an older basement without using foam (rigid or spray). I've gotten input from a few several weatherization folks, but the information varies and seems pretty expensive. I'm looking for an affordable solution that will work. (Photos are attached).

My goal is to 1) air seal and insulate the rim joists, 2) air seal the above-grade brick. I will eventually insulate the brick when budget allows.

Crushed rock or plumbing rough-ins first?

New construction, Superior Walls & slab on grade (daylight on 3 sides, against an upslope bank).

After leveling and compaction, the excavator will provide 8" of crushed stone leveled and compacted for both the Superior Walls (first), then the slab that will be poured to them.

Basement walls

I am building a ranch home and most of the basement (2800sqft) will be finished as living space. The builder has the waterproofing membrane spray on the outside of the basement, the plan calls for 2x6 with r21 insulation batts, and a certainteed membrain. There are drain tiles on the interior of the basement walls and the exterior. There will also be 10 mill poly underneath the basement slab when it will be poured.

Flat roof — sloping and insulation

I own a custom 2-3 story hillside 3300 square foot island home in Gig Harbor, WA (Climate Zone 4C) that was built in 1972. I am the second owner and purchased the home in 1986. The house roofing consists of 80% metal on a 6:12 pitch and a 20% flat roof (~560 square feet) over the bedroom wing with eight ceiling can lights adjoining clerestory windows. The house plans specify R-19 fiberglass batt insulation. The flat roof was replaced in 2001 with a ridge vent and torch down installed.
