PU thermal break profiles create the insulating separation between the inner and outer aluminum shells of a curtain wall or window frame. A low‑conductivity polyurethane composite takes the place of the aluminum web, cutting heat transfer enough to meet Passive House and LEED envelope requirements without thickening the glass.
PU Composite Profiles
Aluminum window frames create a thermal bridge that pulls heat out of a building — polyurethane composite profiles interrupt that bridge. Their structural integrity at a fraction of aluminum's thermal conductivity makes them the quiet backbone of modern high-efficiency fenestration systems.
Quick Selection — PU Composite Profiles
| Application Scenario | Recommended Product Series | Key Consideration |
|---|---|---|
| High-efficiency window frames | Window Profile | Low U-value, structural cavity fill |
| Commercial entrance doors | Door Profile | High stiffness, weather-resistant |
| Curtain wall thermal breaks | Thermal Break Profile | Minimizes condensation risk |
PU Composite Profile Range
Each product page provides detailed engineering information for its specific profile type.
PU composite window profiles form the insulating core of thermally broken aluminum window systems, slashing the frame U-value while carrying the structural loads of the glazing unit. The polyurethane matrix bonds tightly to the aluminum shell during the pour-and-debridge process, creating a single composite section with vastly improved thermal performance.
PU composite door profiles bring the same thermal break principle to commercial entrance doors, where higher traffic and heavier panels demand greater stiffness. The profile cross-section is engineered to resist the racking forces that door frames experience through thousands of open-close cycles.
