It's durable, flexible, and energy efficient.
PVC
A durable, flexible, and fire-resistant material that's popular for commercial and industrial structures.
Modified bitumen
An asphalt-based material that's durable, waterproof, and energy-efficient. It's also capable of enduring
extreme temperature variations.
