Windows provide illumination and help maintain the comfort of your home. Modern, energy-efficient units feature at least two panes of glass with inert gases between them. When the seals of these windows fail, you could face various problems, from drafts to increased energy bills.
Here are five common reasons window seals fail.
1. Material Degradation
Over time, exposure to extreme temperatures, UV rays and moisture can degrade the silicone or polyurethane used to make window seals. As these materials break down, they lose their elasticity and ability to create a tight seal, resulting in air and water leaks.
2. Physical Damage
Physical impact or stress can cause window seals to fail. These seals can also develop issues during extreme weather conditions. Even minor damage can compromise their integrity, causing water intrusion and more serious problems like mold growth and rot around the frame.
3. Improper Installation
Poor installation is another common cause of seal failure. An improperly aligned or secured window can strain sealing materials, causing them to fail prematurely. Working with a reliable contractor can save you from this issue.
4. Condensation and Moisture Buildup
Condensation between the panes of multipane windows is a telltale sign of seal failure. Moisture can enter between the glass panes when the seal that holds them together fails. Besides reducing the window’s insulating properties, it can lead to mold growth.
5. Thermal Expansion and Contraction
Window materials can expand in the heat and contract in the cold. Over time, thermal movement can cause seals to stretch and shrink. It can wear down the efficacy of the seal, leading to leaks and drafts.
