6. Seal Edges – Apply seam tape or additional adhesive around edges if required

📐 Technical Information

EPDM (Ethylene Propylene Diene Monomer) is the industry-standard material for flat roofing, chosen for its exceptional durability and weather resistance. These pre-formed corners are manufactured from the same high-grade EPDM compound used in roofing membranes, ensuring complete material compatibility and consistent performance across your entire roof system.

Material Properties:

• Tensile strength: 7.5 MPa minimum
• Elongation at break: 300%+
• Ozone resistance: Excellent
• Water absorption: <1%
• Flame spread: Class B (EN 13501-1)
