Why Thermal Breaks Matter for Steel Windows and Doors

Steel windows and doors in New York face significant thermal challenges – steel conducts heat rapidly, creating condensation and energy loss without proper thermal breaks. 

Thermally broken steel systems use polyamide inserts to separate interior and exterior steel, preventing thermal bridging while maintaining the narrow profiles that make steel architecturally desirable.

"We engineer the thermal break directly into the steel fabrication – not as an afterthought. The polyamide insert placement affects both the U-value and the sightline. Get it wrong and you either lose energy efficiency or the clean steel aesthetic you're paying for."
