Breathtaking Beauty. Breakthrough Performance

Portella has developed four product lines suitable for any climate and energy efficiency requirements. We are unique in that we specialize in oversize units and we have very few limitations as far as sizing goes because we have our own transportation eliminating restrictions from 3rd party logistics companies.

Our steel windows exceed all industry standards so they are not only beautiful—they are built to last. Portella’s steel windows and doors are made from 100% recyclable, durable steel. We are dedicated to being as eco-friendly a company as we can be and are in the process of becoming members of the US Green Building Council.
