Are injection molded products durable? This air vent shows that injection materials can endure the elements.

17 years on the roof and still plenty of life in it. Another excellent example of when the right materials are utilized; injection molded products can be very durable. This air vent proves it. The fact is, injection molded products are used everywhere. The Auto industry certainly trust them for their cars. Definitely, they are durable enough for the roof. See our Product Design page for more information on the materials used in Robert’s. We heavily invested into research and development to ensure Robert’s will be durable and have long life.

17 years and still very flexible — not brittle.

No spider cracking at the nail gun holes, and no stress cracks.

Leak protection is everything! But Robert’s didn’t stop there. See below all the design enhancements that will absolutely elevate the quality of your work.

Improved Vent Connections – Visual Installations – Rooftop QA Inspection Capabilities
