Why Architects Trust FiberTite

When you choose the wrong KEE roofing membrane, you are risking the integrity of your structure and your reputation. Tears and punctures can be costly and can result in premature failures, tear-outs and damage to your firm’s brand.

When working with critical-to-quality facilities, you need to make sure you are making the best possible choice. One that gives you the premium aesthetics and performance you require, while ensuring decades of proven performance for your clients.

FiberTite is the world’s most trusted roof system for critical-to-quality facilities and has a reputation for being the best single-ply roof membrane on the market. That’s because they are engineered using ELVALOY™ KEE as the foundation and, when combined with some of the heaviest polyester fabrics in the industry, produce a high-performance roofing membrane that remains flexible and retains its physical attributes over time.
