Air Infiltration:
What it means for Your Home

When Chicago winters approach quickly, many of our customers ask us about air infiltration, why it happens and what homeowners can do to remedy it.

Firstly, every home, regardless of age, “breathes” and is not completely airtight. Some natural ventilation between your home and the outside air refreshes the air inside and eliminates excessive moisture which causes mold and mildew. That being said, the problem arises when air infiltration is excessive and leads to frustratingly higher heating and cooling costs.

When deciding whether it’s time to outfit your home with replacement windows and doors, several factors should come into consideration. Most important is the age and condition of your current windows and doors. Obviously—windows, entry doors, and storm doors that were purchased many years ago are not as technologically advanced as products made and installed today. Double and triple-paned thermal glass, argon-filled panes, and superior insulation techniques will make a big difference in a home’s air infiltration. Also, proper installation is among the most important factors that can affect air infiltration and not something to skimp on when purchasing new doors and windows. Confirm that installation is performed by licensed, insured, and bonded employees and not subcontractors.
