Window Care for Beginners: Dealing With Drafts

What are window drafts, and what can be done to fix them? Today, Renewal by Andersen® of San Antonio, a top window and door installation company in the region, sheds light on this issue. 

What Is a Window Draft?

Window drafts occur when outdoor air seeps through the window and into your home. This usually happens when the window lacks an airtight seal even when it is fully closed. The air either seeps through gaps along the frames or along the edge of the glass panes.

What Causes Window Drafts?

Drafts in windows and patio doors typically occur due to wear and tear. Over the years, constant exposure to the elements can cause the window’s components to deteriorate. Linings, weatherstripping and sealants can corrode or become brittle over time, creating the gaps responsible for the drafts.

What Happens When There Are Drafts?

If left unaddressed, window drafts can have serious negative effects on your home’s insulation and energy efficiency. Because unregulated air will keep seeping into your home, your HVAC will consume more energy to maintain a stable indoor temperature. Drafts can also cause humidity and related moisture retention issues in your home.

What Can Be Done?

Fortunately, window drafts are relatively easy to deal with. For minor drafts, you can simply call an expert in entry doors and windows to have the air leaks sealed. If the drafts are caused by severe damage or major gaps in the frame, window replacement may be needed.
