Window Weather Stripping Shrinkage

While they may have been warned, many RV owners don't believe that the window weather stripping on their campers will shrink. The sad, hard truth of the matter is that it can, and if you don't take the proper preventative measures, yours will. All RV window seals will gradually shrink over time, with some shrinking faster than others. The initial shrinkage can cause unsealed gaps of about 1/8 inch along your framed window. This gap can become as wide as 3/16 inches if not repaired after 12 to 18 months. This can lead to drafts, leakage, drops in temperature, and interior damage. Trapped moisture can cause your window frames to crack, rot, and even lead to structural damage. If you notice gaps in your RV window weather stripping, it's crucial to immediately call the RV weather seam repair experts at The RV Shop in New Castle, Delaware. Our technicians will quickly repair or replace your window weather strips to ensure your RV's interior is sealed from outside elements.

What Causes It?

Many things can cause your recreational vehicle's window weather stripping to start shrinking. These include the age of the rubber strips, temperature fluctuations, extreme weather, and normal wear and tear. As your RV's rubber window strips age, the pressure of the seals will decrease. They can also become cracked and rigid. Extreme weather conditions and cold temperatures can also cause your window weather stripping to shrink. Temperatures under 30 degrees Fahrenheit cause the rubber to contract. It will then expand with your camper's heat. This wreaks havoc on your rubber. Lastly, the quality of your rubber window weather strips will also impact the amount of shrinkage. Low-quality rubber seals will shrink faster than higher-quality ones.
