Our new thermally broken system has the narrowest sightlines of any steel door and window system available, has superior energy efficiency ratings, and affords us the ability to customize to our client’s exact specifications.
Where innovation meets excellence
While other steel window and steel door manufacturers purchase profiles from European suppliers, we designed, developed and tested a new profile system. Portella is no longer restricted to offering only specific designs from European suppliers, which opens up a whole new world of options and possibilities.
We have the ability to customize frames and muntin bars to meet the most demanding architectural designs. No other company has this flexibility!
As architects continue to search for narrower frames and sightlines, thermally broken profiles will become an increasingly popular option for any design application. Our new system is fully tested with NFRC ratings that exceed current code requirements.
And here’s the best part…
By fabricating our thermally broken profiles in-house, we are able to minimize costs and pass on those savings. No longer do you need to comprise between design, efficiency, and budget. Thermally broken profiles represent the next great advancement in steel D&W systems.
