Can Wind Cause Poor Window Performance & Seal Failure?

Your home is constantly exposed to harsh outdoor elements and extreme temperature changes. Foggy windows and exterior doors can indicate broken seals. Seal failure can result in inefficient window performance. 

Find out if strong winds can contribute to poor window performance and seal failure. 

What Causes Seal Failure?

Gas fills conduct heat less efficiently than outdoor air, which helps reduce heating and cooling demands. They also prevent window fogging and frosting. 

Throughout the day, your windows face temperature changes. During the day, they will increase in temperature, making the gas inside expand. At night, as the temperature goes lower, the trapped gas contracts. This cycle is referred to as solar or thermal pumping. 

Over time, the stress from thermal pumping can cause deterioration of the seals in your windows or patio doors. Cracks or fractures can form, leading to seal failure and fogging between the glass panes. 

What Can Cause This Problem?

Natural elements and weather extremes will eventually cause window seals to fail. Wind damage can contribute to seal failure in severely damaged or old windows. Debris from strong winds can result in significant property damage. In situations like this, make sure to check if the debris damaged the window seals. During a rainstorm, moisture can get trapped in between panes if the seals are already damaged. 

Moreover, wind damage alone can’t cause poor window performance or seal failure. However, it can worsen any existing damage to your windows.

"Our experience was great, except for writing a big check to you! When Karen and I started the replacement procedure we wanted a quality product. We wanted a company with really, not just in theory, stands behind their work. After reading many reviews and visiting with several people we chose Renewal by Andersen. During the buying process we felt no high pressure. If we were repeating the process, we would change nothing. All the people we dealt with were knowledgeable and helpful. Dave and Amanda, we appreciate you taking time to explain options in style, color, cost, construction of product, installation process etc. Amanda, we are so glad you recommended the awning kitchen window. Dave, we love the invisible kitchen screen. Thanks. The crew of Nate, Colton and Mike were great! Not only were they competent and efficient workers, they were men we were glad to have in our house. Karen commented she never heard any of them say anything unprofessional or in poor taste. Each day and at the conclusion of the job, they thoroughly cleaned-up any mess. A big gold star to the three of you. You are a great team. The stain matches existing wood perfectly. Thanks for a good job, Dan. Robert, thanks for your contribution to the project."
