Frequently Asked Questions
Q: How do I know which gasket type I need? A: Measure the width and profile of your current seal and compare it with the diagrams provided on each product page. If you need help identifying the correct replacement gasket, please contact us.
Q: What's the difference between Bubble and Flipper gaskets? A: The primary difference between Bubble and Flipper gaskets lies in their shape and how they create a seal. Bubble gaskets have a rounded, bulbous shape, while Flipper gaskets feature a flat or tapered profile, often with a thin fin or "flipper" extending from the base. Both types are designed to compress and create a tight seal when a window or door is closed.
Q: Are Qlon gaskets better? A: Qlon gaskets are premium foam-based seals offering superior insulation and longer-lasting performance.
Q: Can I fit these myself? A: Yes — most are designed for DIY fitting with no adhesives or special tools required.
Gasket Materials & Their Advantages
Q-Lon Gaskets: Made from polyurethane foam, which is known for its high durability and ability to withstand wear and tear. Q-Lon gaskets offer superior compression recovery, meaning they bounce back to their original shape after being compressed, providing long-lasting sealing performance.
TPR Gaskets: Thermoplastic Rubber (TPR) gaskets combine the flexibility of rubber with the strength of plastic. They offer excellent weather resistance, UV stability, and maintain their sealing properties across a wide temperature range, making them ideal for external applications.
EPDM Gaskets: Ethylene Propylene Diene Terpolymer (EPDM) is a synthetic rubber known for exceptional weather resistance and longevity. EPDM gaskets resist ozone, UV rays, and extreme temperatures, making them perfect for long-term outdoor use with minimal maintenance required.
PVC Gaskets: Polyvinyl Chloride (PVC) gaskets are cost-effective and offer good chemical resistance. They're lightweight, easy to install, and provide reliable sealing for standard residential applications, though they may be less flexible in extreme cold conditions compared to rubber alternatives.
