Does Attic Insulation Help With Humidity

Hi i am hoping someone might be able to shed some light on a humidity mystery.

Does attic insulation help with humidity.

With outside temperatures ranging between 5 f and 95 f attic temperatures range between 48 f and 92 f. Attic temperatures can easily reach 150 degrees fahrenheit in some instances. We mean that literally by the way. Yes we did increase the attic insulation r value when going to cellulose but i have tried running the ac much longer by basically shutting off registers in the room where the tstat is and i know that the ac is running pretty long that way but still it fails to reduce humidity to less than 55 by itself.

This is because insulation that has become wet does not function as well as dry insulation. During the hot summer months heat enters into the attic space through the roof and increases the attic temperature significantly. Also we have an encapsulated conditioned dehumidifier and supply vent crawl with a radon system. When you insulate the top of your attic with spray foam you re bringing your attic into your home s envelope as a result you can reduce the temperature in your attic by a lot anywhere from 120 degrees to around 95 during peak summer.

These can include installation of seamless gutters and downspouts. Attics with spray foam insulation are so cool. I had my attic insulated with blown cellulose and air sealed i hope. The best way to insulate your house or church school or office building greatly depends on what type of environment you live in if you look at historic houses and buildings you can learn a lot about how to design for your climate because early builders had to adapt to the local conditions to try to make buildings as comfortable as possible.

A moist attic means moist insulation and moist insulation is less effective. Advani hopes to finish the attic and install a minisplit although he s not sure that will lower the humidity. Since that time my home has gone from around 45 48 rh to 52 56 rh humidity 73 74 degrees. Only about 10 of the hip roof is shaded so it gets plenty of direct sunlight.

Adding the right amount of insulation can prevent excess humidity and liquid or frozen precipitation from entering the attic space which protects the space and anything stored inside of it. Moisture control is an important issue when you think about the insulation in your home. Similarly by improving your insulation you can help to improve the levels of humidity in your home. Excess heat and humidity in the house come hand in hand and the main culprit in this case is the attic.

Humidity settings are another issue that can make or break the performance of your heating and cooling systems and your attic ventilation. When an attic is poorly insulated the space may be infiltrated by humidity precipitation and even bugs or vermin. The normal indoor humidity range in winter should be 15. If the problem is the result of water or moisture penetrating the foundation or floor slab there are many remedial actions which may help.
