I have a client with a failing Grailcoat job in NC. The house is framed with 6" Insulspan walls. The Grailcoating apparently cracked, let in water, and there are numerous soft spots in the outer layer of the SIP's OSB.

1. Has anybody had a Grailcoat job fixed?

2. Did the fix work, and what did it look like?

3. What is the proper way to repair a SIPs panel?

Thanks for any help.

I have a 2-story ICF showcase home we are building in Central Florida. My gut tells me thin brick is the better route. Unfortunately, I must be the first builder in CF to build with brick over ICF and have no details from the architect or manufacturer specific to ICF with brick. The biggest problems to solve are figuring out the details around doors and windows and where the first floor roof deck hits the 2nd story ICF wall…any comments?

My 1600 sq. ft., 7-year-old, 2-storey home in the Pacific Northwest has cathedral ceilings insulated with fiberglass batts and covered with cedar-faced plywood panels. The joints are covered with 1x3 fir. A recent energy audit showed immense heat loss through these joints and the auditor recommended air sealing the ceilings by covering the plywood with drywall. Bids for this are coming in around $4000.

Hello, I have been reading so much about flash and batt lately I am second guessing my original plan to insulate a home we are building. We had anticipated dense packed cellulose walls (9 1/4" cavity) and 24" of blown in cellulose in the attic. Are there significant reasons to flash both or either of these areas with foam first? If so should I just go to an open cell foam for everything? Seems like much of what I am reading is contradictory, what is the right choice here?

I am having a new home built in MA. The exterior walls are the ZIP wall system which provides air sealing at the exterior. I have 2x6 interior wall studs. I was planning to use rigid polyiso foam for insulation getting me to ~R27+ @ 4.5 inches. Now I discovered that the polyiso insulation has foil facing. Can I use this product layered in the walls safely without causing a potential moisture problem? Can I face the foil to the exterior to repel summer heat and to the interior to help retain winter heating within the house.

I have a beach house in NH, 24 x 36 with 2-ft. overhangs. The entire house is cathredraled using 6 pitch 4x6 trusses and sheathed with 1x8 T&G boards. Each roof side is 15' x 44'.

There is no insulation except for 1/2-inch Homosote sheets between the trusses which are stuccoed over. The roofing is relatively new (5 yrs). So I would balk at tearing it off.

Cost is a big factor here. We don't have a lot of money. I have no problem putting a new ceiling on the inside but I need a cost-effective way of insulating the 4-ft. bays. Any help would be appreciated.

If one is already planning R10 insulation outside the perimeter of the foundation wall such as Tremco's Warm-n-Dri and their Horizon finishing system above grade, is it also a good idea to add rigid foam insulation on the inner side wall of the poured basement slab? Image is to have R10 subslab rigid insulation along with a shorter rigid insulation wall section (R10) along the perimeter of the basement slab. In other words, should the rigid be applied just outside the foundation or outside the foundation as well as the perimeter of the concrete floor.

Anyone know where I can purchase Tremco Acoustical Sealant for a good price?

Everywhere I look its going for about $16 per 30 oz tube!

I can get OSI Draft and Acoustical sealant for $6 per 30 oz tube from a local supplier.

Does anyone has any experience with the OSI brand?

Wanted to find out if you could recommend a low/no voc waterproofing product for inside steam shower and any low/no voc grout for tile? Our builder usually uses Superflex but hoping to find another product that is green and just as effective long term.
Thank you!
