As temperatures fluctuate and extreme weather conditions become more common, your home needs to stay protected. One essential component of weatherproofing your property is EPDM weather stripping. If you’re wondering whether your current weather stripping can withstand harsh conditions, here’s everything you need to know.
What is EPDM Weather Stripping?
EPDM, or Ethylene Propylene Diene Monomer, is a versatile synthetic rubber commonly used for weather stripping due to its excellent resistance to heat, ozone, and corrosion. This material is ideal for doors and windows, providing an effective seal against air and water leaks. However, despite its durability, EPDM weather stripping can fail over time or under extreme weather conditions. Understanding when and why this might happen is vital for maintaining your home's integrity.
Signs Your EPDM Weather Stripping Is Failing
Recognizing the signs of deteriorating weather stripping can help you take timely action before the situation worsens. Here are some common indicators:
1. Cracking or Peeling
One of the most visible signs is cracking or peeling of the weather stripping material. EPDM is designed to resist extreme temperatures, but prolonged exposure to direct sunlight can still cause it to degrade over time. If you notice cracks, it may be time to replace the stripping.
2. Increased Energy Bills
If your energy bills rise unexpectedly, it might indicate that your EPDM stripping is failing. Poor seals allow heated or cooled air to escape, resulting in your HVAC system working overtime. Perform a simple test by feeling for drafts around doors and windows.
3. Water Leakage
During rainstorms, if you find water seeping through the edges of a door or window, it’s likely due to ineffective weather stripping. Check for gaps and inspect the condition of your EPDM material to identify a possible failure.
Common Causes of EPDM Weather Stripping Failure
Understanding the factors that contribute to the failure of EPDM weather stripping can help you prevent future problems. Here are the main culprits:
1. UV Damage
While EPDM is formulated to resist UV radiation, long-term exposure can still lead to degradation. Consider using a UV protectant spray designed for automotive or exterior applications to extend the lifespan of your weather stripping.
2. Extreme Temperatures
EPDM can handle a wide range of temperatures, but extreme shifts can weaken it. If you live in an area with significant temperature changes, consider replacing your weather stripping with a product specifically designed for extreme conditions.
3. Poor Installation
Sometimes, the failure is not due to the material itself but rather improper installation. Ensure your weather stripping is applied correctly, making tight seals without any visible gaps.
How to Replace or Repair EPDM Weather Stripping
If you’ve determined that your EPDM weather stripping is failing, taking action is essential. Here’s a step-by-step guide for replacement:
1. Remove the Old Weather Stripping
Use a utility knife or similar tool to carefully cut away the old EPDM weather stripping. Be cautious not to damage surrounding surfaces.
2. Clean the Surface
Before applying new weather stripping, clean the area thoroughly to remove any remaining adhesive or debris. This ensures a better seal with the new material.
3. Measure and Cut New Stripping
Measure the required length and cut your new EPDM weather stripping accordingly. It’s essential to be precise for the best fit.
4. Apply New Stripping
Peel off the backing from the adhesive side and press it firmly into place. Make sure there are no gaps and that it forms a tight seal.
5. Test for Effectiveness
After installation, check for leaks or drafts. A simple dollar bill test can help; if you can pull the bill out easily, consider adjusting the sealing.
Frequently Asked Questions
