PART2 KCC Window
14 http://www.kccworld.co.kr
PART2 PVC+AL Window
Purpose
Curtain-wall consists of PVC for inside and Aluminum for outside
- Aluminum for outside: Wind proof & Curtain-wall elevation
- PVC for inside: Higher U-value & Leakage Proof
Specification
1) Window-frame width: 225mm
2) Window-frame depth: Inside - 82.5mm / Outside - 65mm
3) U-value: 1.4W/㎡K [22T Clear Pair Glass basis)
4) Wind Load (High class –Level 360) / Sound Proof (RW47) /
Air Tightness (High class – Level 1)
Benefit
1) Design affordability by Curtain-wall elevation
2) Flexibility in opening and shutting
3) Higher Performance (Ventilation, U-value, Less thermal bridge)
