What are the main advantages of Everything Ponds RPE Liners over EPDM liners?

The Everything Ponds Premium RPE Liner is 3 times stronger than EPDM, is significantly lighter (1/3 of  the weight), and can be custom-sized up to 60,000 square feet in a single panel, without the need for onsite seaming. It often requires no underlayment and has a 20-year warranty in direct sunlight, making it more versatile and cost-effective for large projects. EPDM rubber on the other hand, often requires seaming on-site since large panels are often not available due to weight.
