Common Causes of a Drafty Window

Aside from letting you control the airflow in your home, windows add functionality and beauty to your home. Unfortunately, they can also be a source of drafts that cause discomfort in your home.

Renewal by Andersen® of Central Illinois, the premier expert in replacement windows in Springfield, IL, talks about common reasons that lead to drafty windows.

They are Worn Out

Constant use and exposure to harsh climate conditions can cause a window to age and become inefficient. Its strips and seals might then deteriorate, providing an opening for drafts to pass through. Rotten frames can let drafts in, as well.

With our replacement windows in Decatur, IL, you can be sure that they keep the elements out, given their resilience. They feature our Fibrex® frame composite that is made of reclaimed wood fibers and polyvinyl chloride (PVC) from Andersen® Corporation factories. This gives them the natural beauty of wood, twice the strength and low-maintenance features of vinyl. This means they can resist rotting, warping, and blistering, for lasting performance.

Sudden Changes in Temperature

Depending on the frame material of a window, sudden changes in the outdoor temperature can cause it to contract or expand. This can let drafts in your home, which creates fluctuations in the indoor climate.

Fortunately, our windows feature highly-insulated components and resistance to extreme temperature. For instance, they come with High-Performance™ Low-E4® glass that can reduce the amount of heat that enters and leaves your home. This will make sure that your home is cooler during hot seasons and warmer during cold weather. Couple this with our Fibrex composite frames and you can be sure that drafts won’t be a problem in your home.

Poor Installation

Poor workmanship can cause a window to perform sub-optimally, allowing drafts to enter your home. That’s why we make sure our crew is factory-trained and experienced in installing windows in Springfield, IL. You can be confidant that your windows will be airtight.

In fact, part of our installation process is applying insulating foam in between the gaps of your old window frames and new windows. This will ensure that they keep the elements out and your conditioned air in. Furthermore, our windows come with exclusive and limited warranties for your peace of mind.

At Renewal by Andersen of Central Illinois, we can help make sure your home stays draft-free through a range of window styles. Call us today at (866) 693-6707 to schedule a FREE, in-home consultation.


"I would recommend RBA of Central Illinois for QUALITY windows and doors. Compared to our old cheap, thin vinyl windows, Andersen blows them away. You can easily tell by how well the sliding doors fit and close, and how heavy duty they are. We also cannot hear the wind rushing through the house in inclement weather anymore! And the black window frames we went with are amazing to look at. Aaron, Al, Darrell, and Cory all were professional and went all out to finish the job, given the weather they had to deal with. I would definitely recommend. They were also on top of communicating with me given the weather delays, and what I could expect for them coming out. Five stars!"
