We guarantee our work for every project and each Portella window carries an exceptional warranty that goes way beyond the industry standard to protect the longevity of your investment. Check out our steel window frames for kitchens.
With narrow sightlines and custom shapes, our window configurations can fit virtually any application to meet the demands of discerning homeowners and businesses alike. Creating custom size steel windows allows us to work directly with builders and architects and meet the exact specifications of their projects. Most importantly, our state-of-the-art manufacturing processes and factory glazing allows us to keep every process in-house. That eliminates subcontracting and mark-ups so we can deliver the finest quality steel windows at the best possible price.
We currently manufacture four categories of steel windows, each of which features a number of unique designs. Our product lines include:
- Thermally broken – Our thermally broken windows exceed all energy efficiency requirements. We are the only steel window manufacturer to include a thermally-bonded zinc galvanizing corrosion resistant coating. That ensures your new windows last a lifetime even in the harshest climatic conditions.
- Classic – The classic range of custom steel windows is the perfect complement to contemporary architecture, featuring slender lines and minimalist profiles that let light flood into your home.
