Quality, Tested and Certified
When we talk about performance for Portella’s metal doors and windows, it means verifiable dedication to a rigorous product development and testing cycle that guarantees every product we produce meets and exceeds standards. In addition to third party testing, our steel doors are certified with ASTM, NFRC, and AMAA, with Florida Building Code certification on the horizon.
With our commitment to improving our product lines and surpassing standards with every new round of production, we hope to provide a cross of functionality and stunning design perfect for your next set of custom windows or steel doors in Denver.
Warm in the Winter
Denver can present a unique challenge for windows or doors with metal frames when it comes to thermal conditions and the general climate of Colorado. Fortunately, our Artisan Series is crafted with a variety of thermal and energy efficiency challenges in mind. This allows us to offer Denver designs and materials that were previously unavailable due to difficulties with climate and weather.
With traditional metal frame windows and doors it’s easy for temperature fluctuations to affect heat gain or loss from the metal frames. With the Artisan series, we’ve introduced a GRP (glass reinforced polyacrylamide) which is a non-conducting material that reinforces strength and thermal performance, keeping the cold air in or out depending on the season.
Portella’s interest in continued excellence encompasses more than just our high quality product lines. From beginning to end, our aim is to build architecturally proven products and strong relationships with builders, architects, and businesses interested in the absolute best custom steel doors and windows. Here are a few points that highlight all we have to offer:
- Patented, narrow profile sightlines to see more of the Denver mountain ranges
- Factory installed glass featuring Low-E options to regulate energy efficiency
- Metal stops or traditional wet glaze, with interior or exterior glazing options
- NFRC rated thermally broken simulated divided lite or true divided lite options
- Clear, concise, one-point communication with one of Portella’s knowledgeable Project Managers from the very first quote to drafting.
