The simple physics behind sweating is.
Attic condensation in summer.
In the winter the condensation will form frost and in the summer this condensation can grow mold.
Wherever your a c cooled air is entering may be cooler and when that muggy summer air contacts any cold surfaces you may notice the attic condensation problem.
Why is that important.
They keep your home cooler in the summer warmer in the winter and free from damage caused by moisture.
The main goal is to keep your attic temperature the same as the outside air temperature in the summer as well as in winter.
The issue in the attic is that at 48 degrees f.
In summer when the air conditioning is on the reverse happens.
What you see is condensation also known as ductwork sweating.
Improper or no insulation of ducts.
How to completely prevent condensation once you ve blocked the common entry points for air and thus moisture penetrating your attic space you can prevent moisture from accumulating in your attic in two main ways.
On hot days you may notice water droplets forming on your visible air ducts and wonder whether this is normal.
Attic insulation and ventilation go hand in hand.
If you seal up the leaks on lower floors you may do without the humidifier and stay comfortable.
If there is excessive moisture accumulation in your attic it will condense on cold areas mainly on the underside of your roof deck.
How does condensation get in the attic.
Good insulation is a must because it minimizes the amount of warm air entering the attic to begin with.
If there are signs of rot on the roof sheathing then there has been prolonged moisture in the attic.
There are plenty of things you can do to minimize attic condensation from occurring.
Summer is the time of year when your air conditioning unit has to work the hardest to cool your home.
You are approaching the 43 deg dew point and some colder surfaces like windows you will get condensation there.
Looking for signs of moisture.
This is especially important in your attic bypasses areas connecting to your home like heating ducts kitchen exhaust fans lighting fixtures bathroom vents etc.
The first signs of a condensation problem in your attic might show up during a re shingle on your roof.
Improving your attic s air sealing and insulation prevents attic air from reaching your ceiling and it s a fairly easy job to do yourself.
Whenever there is a contact between the hot humid air and cold metal surface then there will be sweating or condensation on the metal surface so it is very important to have a proper insulation for the air handler ducts in case the portion of the duct is coming in contact with the.
Start by checking your attic s insulation level.
Improper ventilation and insulation of home attic space can produce high humidity levels and trap.
Moisture accumulation is most significant when outside temperatures are very cold because air holds less moisture as the temperature decreases.
Condensation on your ceiling can cause water damage and promote the growth of mold or mildew.
That s just the properties of moist air.
Extra heat build up under the roof deck can cause your shingles to deteriorate much faster sometimes cutting their life expectancy in half.
