Solar radiant

Has anyone on the site tried to do solar radiant heating with a collector and pex in zone 6? I'm trying to avoid using propane in the house and I'm wondering how/if radiant solar works in a cold climate. I just need some supplemental heat for my wood stove and electric baseboards..

Reuse SIP polystyrene cores

I am building my home and ordered SIPs for the roof and walls. This was 3 years ago! We fell short on funds and the home remained untouched during this time, until we were able to rebuild our bank account. During this time the panels suffered moisture damage (replaced the tarps that covered them 3 times even!) and we were not able to use them. We continued with stick framing instead. We were left with all these panels laying around, so we stripped the rotten OSB leaving just the polystyrene cores. All the moisture was removed and they were put in storage.

Raised concrete slab?

My wife and I just purchased a moderately sloping lot in northern Arizona, near Flagstaff and we're in the initial stages of designing a roughly 1000 sq. ft. home. Due to it's 6000+ft elevation the area can get significant snowfall in the winter. Since the lot is downslope from National Forest land we have concerns about drainage thru the soil, particularly with spring snowmelt.

Insulate Supply Line in Attic?

Hi, I'm trying to get a little more efficiency out of my HVAC system and I'm wondering whether to bother with attempting to insulate some supply lines that are in the attic of a commercial building. The attic is within the thermal envelope but it is unconditioned. The attic is used for storage and therefore has a floor. All the supply lines have been mounted flush on top of the floor and I can feel major air leaks at all the seams/connections. My idea is try to slightly lift sections and apply mastic tape to the seams on the bottom as well as apply mastic to the sides and top.

I Used the Wrong Nails

I am framing a first floor deck and I used the wrong nails. I shot 2" x 0.99 ring nails instead of 2 1/2" common. The floor is 11 7/8" I-Joist with 3/4" Pinnacle sub-floor. I applied plenty of construction adhesive and only attached the sub-floor only one sheet ahead of the adhesive application. My nailing pattern is about 4" to 6" along the perimeter and 6" to 8" in the field. Should I go over it with the correct nails?

Humidity in Basement

Last year we added an addition onto our house located in Nova Scotia on the Bay of Fundy.The foundation is ICF and the header spaces are insulated with spray foam. There is drainage tile around the outside of the foundation. The problem - I'm getting around 4gal of water a day from my dehumidifier in the crawl space! (unheated). The floor of the crawl space is earth/sand/PLASTIC/Sand. There is no standing water and no signs of leakage but the top layer of sand is wet in some areas. There is no ventilation in the crawl space. Any ideas on how I can remedy this?

An open thank you letter for GBA's help making my house more efficient

To Martin and all at GBA,

Im a home owner (built 2007) 2700 sq ft Colonial in Rockland County NY (Zone 5)

Ive been following various discussions on reduction in energy bills by increasing insulation and sealing the airleaks

By adding 6' of loose blown cellulose to the R38 in the attic (used GreenFibre and machine from Lowes) and filling the ceiling of garage (has fibreglass batts but huge airgap so used the Greenfibre machine to dense pack the ceiling and completely fill the space.
I airsealed the rim joists and top plates/attic as well

Does anyone have an opinion regarding zinc strip installation to deter moss?

I have read pros and cons on installing zinc strips to deter moss and lichen. My House is surrounded with pine trees and I have a good amount growing on the north side of my house. Im hoping Martin will chime in with his opinion on this. Is it worth the expense? Will it do more harm than good? Thanks all
