measuring and controlling humidity

To determine how much humidity is present in your home, you can purchase a humidity
gauge from a hardware store or home center. Invest in a quality unit for greater potential
accuracy in assessing humidity levels, or consult an expert. Another way to monitor the
interior humidity level is to watch your windows and doors. When interior condensation
begins to form, wipe it off. To reduce the humidity, open windows, run exhaust fans or
dehumidifiers, or minimize sources of moisture.

exterior condensation

Exterior condensation on windows and doors occurs primarily in the morning when days are warm and humid, but nights are cool. Typically, it
clears as the day warms. Exterior condensation can occur at any time, especially in warm, humid climates where interior temperatures are cooler
than outdoor conditions. Exterior condensation means that windows and doors are doing their job properly. However, if you spot excessive
condensation on the inside of your windows or doors, check your inside humidity — it may be a signal of potential problems if not addressed.

tips for wintertime moisture management

• Open window coverings — such as blinds, shades, drapes and curtains — during daylight hours to increase airflow over the glass.
• Closely monitor the furnace humidifier and any other humidifying devices.
• Be sure louvers and vents for the attic, basement and/or crawl space are open, adequately sized and cross-ventilated.
• Run exhaust fans for kitchen, bathroom and laundry rooms for longer periods.
• Make sure exhaust fans vent directly outside, not into attics or crawl spaces.
• Be sure chimneys are free and clear so moisture in combustion gases can escape.
• Follow the manufacturer's instructions for venting gas appliances. In most cases, that will mean directing vents to the outside of the home.
• Make sure your furnace is in proper working order and is serviced regularly.
• Store firewood outside or in the garage — as wood dries, it gives off moisture.
• Install energy-efficient products, such as those that have earned the ENERGY STAR

note: condensation that forms in between the panes of insulating glass is not considered "roomside" condensation. instead, this is an indication of glass
seal failure, which cannot be corrected. contact your Pella representative if this occurs.
