Cellulose installation in the wood joists area and wall perimeter

I have read through several posts and articles about insulating floor joists/rim joists, including http://www.greenbuildingadvisor.com/blogs/dept/musings/how-install-cellu..., but did not find the answer.
We have a dense pack cellulose specified in the wall perimeter, in the area of 16'' D open web wood joists @ 24'' OC between floors.

Stain or not stain a new custom solid mahogony front door?

Hello All,

Just had our custom front door (10 'x 14') in solid mahogany delivered & installed but not sure whether we should stain it or not?

Wife prefers a reddish stain (makes it look richer) but the wood work guy says leave it alone and just clear coat it using a oil based polyurethane coat and be done with it.

Can I get some feedback here?

Air sealing common wall between garage and house


I'm starting to frame my house, which is going to share the 12'x28' 2x6 wall of my existing garage. Garage wall is taped sheetrock, poly sheeting, r-19 fiberglass, and OSB. The garage will not be air conditioned (may use dehumidifier in the summer) and will be heated to at least 50 all winter. I live in zone 7a. My question is how meticulous should I get with air sealing between the garage and house and what would be the easiest and most effective methods? Would air sealing create a problem with the poly on the other side of the 2x6 wall? Any help would be greatly appreciated!

Furring out interior of stud 1.5"

I am about to order my mineral wool insulation from menards. They have two options I am interested in. I have 2x6 stud walls 16" o.c.

They sell Thermafiber UltraBatt 5.5" x 15" x 47" R-23 Mineral Wool Insulation & Thermafiber UltraBatt 7" x 15" x 47" R-30 Mineral Wool Insulation

According to my calculations it would only cost $365 more for the 7" deep insulation.

Outie window using Roxul

I am planning on using Roxul 3" exterior insulation for the exterior walls, I want to install windows using the "outie" configuration and would like to have a simple method that gives me a wide nailing surface for the window flange and window trim. this is a 200 year old house that will have varying degrees of insulation(2nd floor walls will be 2x6, 1st floor walls will be 2x4). at the windows and doors I am thinking of installing picture frames made up of 2" extruded poly with a 2x6 on the flat which would give a nice wide nailing surface while breaking up the thermal bridge.

I need some professional input on how to create a storage space in my attic

First of all I am not even sure I am in the right forum to ask my question. Please excuse me if I am not and maybe some one here can point me in the right direction.

I live in Myrtle beach SC. My house was just built. It is a cape cod style with an attic, accessed by drop down ladder in the garage. It has ridge vents and soffits and no gable vents. All up to current SC code.
I would like to store some post WW2 Lionel trains and various Christmas decorations in the attic. My questions are:

Supply and returns in sealed attic in hot/humid climate

I have a new construction house on the coast in South Carolina which has been spray foamed with closed cell in the crawl space( at the subfloor), closed cell in the walls, and open cell at the roof line. In hot/humid climates, I have read there needs to a small amount amount of conditioned air released into the "sealed" attic to slightly dehumidify and circulate the air. The rate mentioned was 1 CFM per 30 sq ft of floor space. This is the same amount the codes require for sealed crawl spaces in NC.

U.S. availability of rigid mineral wool

Is Roxul Comfortboard IS or some suitable substitute readily available in the United States? I found a few discussions of this issue in comments to earlier threads, but those were a while back or specific to particular cities. Roxul's website lists Home Depot and Lowes as dealers, but they appear to only carry the batt types.

Insulation for attic conversion with 2x4 framing

We are converting our attic to living space and I am looking for input on the best way to insulate the space. The home is in Portland, Oregon and there is limited room for insulation because the roof is framed with 2x4 rafters (picture attached) and we can't fur out the space due to ceiling height. I was considering using closed cell spray foam either alone, or in combination with some other form of insulation. Any suggestions would be greatly appreciated.
