- All About Attics - GreenBuildingAdvisor
Most six-year-olds can draw a house The typical child’s depiction of a house shows a rectangular building with a door and a few windows, topped by a gable roof This type of house is fairly common in most areas of the U S If the house was built 100 or more years ago, it usually had a cellar or basement underneath the first floor and an attic above the top floor
- Air Leaks From Your Home To Your Attic Need To Be Sealed
It’s important to keep attic air out of the house and house air out of the attic That's why the home performance industry and every above-code building program make it a top priority to fully separate attics from the rest of the building When the attic isn’t fully air sealed from the living space and the combustion appliance zone, three undesirable scenarios can occur:
- Should I vent my unvented garage attic? - GreenBuildingAdvisor
The house attic is insulated with R-42 open cell foam on the roof deck, and there is currently no insulation in the garage attic The wall between the house attic and the garage attic is drywalled and insulated with R-30 open cell foam on the house side The garage has fire sprinklers, so the garage ceiling will need to be drywalled
- Finalizing insulation in converted conditioned attic
Because the attic sits above an insulated but unconditioned garage, I have ~R-60 of blown in cellulose on the attic floor garage ceiling Since the cavities have 9 5 inches of rafter space, I had originally planned to add R-15 Rockwool batts to the cavities and, potentially, cover all of it with R-6 Rockwool Comfortboard 80
- Ducts in an Unconditioned Attic - GreenBuildingAdvisor
There are two options for locating ductwork in an attic The first is to move the building’s thermal boundary from the attic floor to the roofline, which places the ductwork inside conditioned space The other is to bury ducts in a layer of insulation on the attic floor, leaving the balance of the attic unconditioned
- Are Powered Attic Ventilators Ever a Good Idea?
There is no vapor or reflective barrier on the attic ceiling, just wood and nails During the day our house stays relatively cool with all the windows closed But come around 7pm until about 11pm it’s hotter inside than out (all windows open now), and from a thermal camera it looks like the attic is dumping stored heat down into the house
- Attic baffles question - GreenBuildingAdvisor
But you also want to reuce wind washing, and working in an attic is difficult Like you, I've found hitting things with a can of spray foam is the simplest easiest quickest solution It closes gaps, seals things, and adheres things, all with minimal precision needed You can do it from an ackward position in the attic and get the job done
- How to Insulate and Air-Seal an Attic Hatch
Even though attic hatches can be huge air leaks and sources of radiant heat loss, they are rarely fixed An attic hatch is usually located in a hallway or closet where the homeowners see it daily Yet… I mean, once the homeowners fire up a blower door and whip out their infrared camera, the problems with attic hatches are pretty obvious
- Installing an ERV in an Unvented Attic - GreenBuildingAdvisor
The attic stale air pickup should be near the ridge because usually the highest humidity is there, this is the air you want to move out of your attic This hot humid air that is pulled out will now be supplied with conditioned air from the house thus indirectly conditioning your attic
