Frequently Asked Questions

Q1: What are the primary advantages of EPDM over PVC seals? EPDM provides significantly better UV, ozone, and temperature resistance. While PVC can become brittle over time, EPDM remains flexible for 15-25 years.

Q2: Can I get custom shapes or profiles for my project? Yes, we specialize in custom profiles (D-shape, P-shape, tubular) and can adjust density and hardness levels to meet your specific sealing requirements.

Q3: What is the operating temperature range? Our enhanced EPDM sealing strips perform reliably in a broad temperature range of -50°C up to +130°C.

Q4: Are these seals suitable for outdoor glass curtain walls? Absolutely. EPDM is the industry standard for curtain walls due to its exceptional resistance to environmental oxidation and thermal shifts.

Q5: Do you offer adhesive-backed options? Yes, we can apply high-strength self-adhesive backing to most profiles for quick and easy peel-and-stick installation.

Q6: Are the materials environmentally safe? Our EPDM strips are crafted without PVC, halogens, or heavy metals, making them ideal for green building certifications like LEED and BREEAM.
