The thermal qualities of EFCO's 5600 and 5900 curtain wall systems are enhanced with the addition of a Pella patented Duracast® fiberglass pultruded material. Utilizing this advanced technology, EFCO has designed a pressure plate that is far superior to the aluminum pressure plate for thermal conductance, while providing an overall 27% gain in frame and glass U-factor and 10% improvement in CRF. In addition to outstanding thermal improvement, Duracast fiberglass composite is stronger than conventional fiberglass due to a proprietary manufacturing process. The use of Duracast also eliminates the need for a thermal isolator between the mullion and pressure plate.
- Thermal isolator not required
- Fewer installation steps
- Alternative to aluminum pressure plate
- Comparable structural values
