Performance Testing

We’re proud to provide unique steel doors and windows that are a product of a constant cycle of testing and product development. To ensure that you receive only the most up to date products, we have our doors and windows third-party tested and certified. With ASTM, NFRC, AMAA, and soon Florida Building Code certifications, you can trust that our steel installations will work for your next project.

Expanding in Baltimore, or updating a restoration project with a new look and stylish metal framed doors or windows? Our product lines can be custom built to fit your particular needs all while meeting and often exceeding standard building codes.

Solving Thermal Challenges

With metal frame doors and windows, manufacturers often struggle to address the thermal challenges that come from losing or gaining heat where the glass meets the frame. While others offer insulated glass designs that fall short of solving the thermal transfer along the frame, our Artisan Series introduces a GRP (glass reinforced polyetherimide) which acts as a non-conducting material to strengthen the build and reinforce thermal performance.

This translates to higher energy efficiency, climate resistant builds, and a more controlled thermal environment thanks to our innovative designs and development.
