NAME uPVC (unplasticised polyvinyl chloride)
MATERIAL CHARACTERISTICS
Acrylic modified high quality impact resistant,white unplasticised polyvinyl chloride material with multi chambered extrusion,in accordance with DIN 7748(79) PART 1 & RAL - STANDARD RAL -92716/1
FM DIN 7748-PVC-U,EDL-082-35-28
U = unplasticised
E = Extrusion Material
D = Powder
According to static calculation and usage
CORNER WELDING & STRENGTH
Homogeneously welded
RAL-G-Z 716/1 DIN EN 514 BS-7413
SOUND INSULATION
The double sealed window design( inside and outside weather stripping) along with the reinforced multi chambered profile results in excellent sound insulation.DIN 4109 typically reduction value is Rw. 30 dB-42 dB (based on 6/12/6 double glazed unit)
THERMAL CONDUCTIVITY
The Thermal insulation value is an important factor to save energy for heating and air conditioning.The multi chambered profile have an U-Values range between 6.0-1,0 W/m2k where the smaller value is the better one.The K-value of U-PVC is 0.16 W/m 0C.(0.138 Kcal/m h 0C)
WIND RESISTANCE
The wind resistance is tested in accordance with BS 5368:PART 3,EN 77.The maximum allowed defection is V300 or 8mm between two edges of an insulating glass unit .Gust of wind is repeated test (50 times) at + 1000 Pa.for classification "C" .there shall be no permanent residual deformation,damage of functional defects.
WATER TIGHTNESS
The Water tightness is tested in accordance with BS 5368 PART 2,EN 86.there will be no leakage at a certain wind pressure,amount of sprayed water and time.Typical classification for tilt and turn is group B and C,300 and 600 Pa
