Attic Insulation
 
In my attic I have the ability to close off these huge traingular vents on each end of the house. They have a base about 8 ft long and aprox 3 ft high from the base to the peak.
I keep these open in the summer, but thought maybe to close them in the winter to keep the upper floor warmer.
Then I heard "some expert" say that the attic should stay aprox the same temp as outside, otherwise moisture drastically reduces the insulation's effectiveness. (Potentially making the house colder)
What do you guys think??
Should I close the attic vents in the winter? (My attic insulation is old and crappy anyway)

Simple answer: Your attic needs ventilation even in the winter months.

spend your time and money on up grading your insulation.

With those type vents crawl up there on the worst day of the year,,,duing a blizzard,,,OR if it doesnt snow there during huricane force rain event,,,and SEE if it is allowing moisture inside and what area. Then try to pan that or somehow control moisture intrusion,,,or collect it!! Like tinning up a chute where the water HAS to run outside before it runs down into insulation and drywall and other finished surfaces!!
