A Solution to Steel Door and Window Thermal Challenges

Portella’s Artisan Series is a solution for New York’s luxury residential, boutique commercial applications or historical projects. Our Artisan Series products have some of the industry’s best thermally broken profiles. Artisan utilizes a GRP (glass reinforced polyetherimide), a non-conducting material with steel, which combines strength and exceptional thermal performance.

Portella sets itself apart from other steel window and door manufacturers by offering only NFRC-rated, thermally broken, laser fusion-welded and cold-rolled option for your steel windows and doors. We invite you to navigate towards our Artisan product pages, where you may peruse through our design guide full of Artisan steel design window and door options.

Frequently Asked Questions

Is it possible to install slim steel entries in historic New York buildings?

Yes, many renovation projects in the city require materials that work well with the original architecture while providing modern strength. We can help you with custom steel doors that feature ultra-slim sightlines, allowing you to maintain a classic aesthetic using high-quality and durable materials.

How well do large glass panels handle the cold winters?

Portella manufactures products with a patented thermally broken technology that creates a barrier against the cold. This innovation ensures that your custom steel windows provide excellent insulation, keeping your home warm and energy-efficient even during freezing temperatures.

What is a good option for a high-end interior partition or a classic storefront?

For those who want the perfect blend of organic warmth and natural light, a wood with a glass door is an ideal choice. These are often used to create sophisticated transitions between rooms or to give a retail space a premium, clean, and inviting entrance.

Can these steel frames be customized for high-rise apartments or penthouse views?

Because New York architecture often involves unique structural requirements, Portella provides tailored options to fit specific openings. Our custom steel doors and windows are engineered to handle strong winds, extreme weather conditions, built using durable materials, and designed according to your space to give you a perfect fit.
