Thermally Broken Steel USA was spec'd on a project we recently completed. The whole process from quote to order entry was simple and easy. Justin answered every e-mail on time and the delivery was on schedule, and that never happens for fire rated aluminum. Our installer, Joe, said it was one of the quickest and easiest fire rated sliders he has ever done. Overall it was quality service and a quality product.

We had used TBS for a new construction apartment complex in Sacramento CA. and we are extremely satisfied with the product, from the great finish, and the pre-punched nailing fin, to dealing with Justin. it was a great experience and we will definitely be working with TBS again.

Had the pleasure of using TBS on a multi-family new construction project in Sunnyvale, CA. Justin was extremely helpful from the bidding process to the submittal/ordering process. They were able to find the exact finish to match the vinyl windows adjacent to TBS fire rates windows. Planning on using TBS for our next fire rates project.

Worked with Justin Grebasch at Thermally Broken Windows. The process was during COVD and the service was exceptional. He gave me a lead time and was able to bet it by one week. Will work with them again.
