IMPACT RESISTANCE :
YASHPOLY U-PVC profiles are specially formulated to withstand high impact. It has an impact resistance of 3 kg
at 1 mm in height room temperature 23 deg. C.

EXCELLENT HEAT INSULATION, ENERGY SAVING
In an air-conditioned building, windows with low thermal conductive material can reduce the loss of energy according to the fact at 37%.
The intelligent selection on factors of thermal conductivity is the material of windows profiles and the selection of the gloss. The thermal conductivity of
U-PVC is 0.14 Kcal/m A 2hr.C* and that of aluminum 175 Kcal/m A 2hr.C* ,for example, the K- value of PVC window having the some glass is
7.6 Kcal/m A 2hr.C* Therefore, the U-PVC windows can reduce the energy loss by over 30%.

CORROSION RESISTANCE :
U-PVC windows are free from the attack of acids, alkalis, waste, and salts. It is corrosion resistant
when used in any envoironment with its high
"tempreture and high humidity.

EXCELLENT WEATHER RESISTANCE :
YASHPOLY U-PVC Window profiles are specially formulated to achieve a high resistance against Ultra-Violet (UV) attacks. It can withstand long
exposure in extreme weather change under scorching sun, storms, dryness and high humidity. Moreover YASHPOLY U-PVC windows provided
perfect isolation against dust, wind and rain for helthier environment this because of the perfect double rubber gaskets isolation and the welded corners.

HEAT AND SMOKE RElEASE
The total heat release when burning PVC profiles is 17 MJ/m2 which is very low as compared to wood. The total smoke yield when burning pVC profiles is 384

ELECTRICAL INSULATION
U-pVC has high electrical insulation which exceed lOA 5 ohms-cm.
It is absolutely safe from electrical conductivity and maintenance free.

ISI/BSI COVERAGE
ISI standards do not exist for pVC doors, windows etc however correspondence for establishment.

EXCELLENT SOUND PROOF:
YASHPOLY U-PVC window material and the special multi-chambered profiles with nonvibrant material property, and thermally assembled
corners dramatically reduce outside noise. An average sound separation of 22-25dB is reached in 6mm glazing and 30dB in double glazing so,
U-PVC window are especially favorable to be used in Hospitals, schools, and offices Buildings.

EXCELLENT FIRE PROOF:
The U-PVC material is an excellent fireproof material according the DIN40 12 for its nonspontaneous and self-extinguishing characteristics
According to the results of window material combustion test with wood, aluminum, and U-PVC assisted by Zurich Fire Brigade on February, 1973,
The U-PVC windowhad been proved no damage and met the stipulation of combustible building material used in high rise building." The U-PVC
window could be used in all kinds of buildings regardless of altitudes in other countries and is knows and accepted as Safety material by Fire
Brigade authorities in Australia, Germany, New Zealand, and US. This is because they contain more than 70% unplasticised PVC which is turn
57% chlorine. This contribute efficiently to the flame retardant. Further it has very high ignition temperature 400°C against 210°C of wood and has
on index of 50% for wood.

LOW THERMAL EXPANSION:
U-PVC window are easily operated even under any weather conditions due to its low coefficient of thermal expansion, which is (3x lOA _5° Clcm).
During summer the average outdoor temperature is 45° C, while the average indoor temperature is 25° C and the temperature inside the profile is 33°C
The maximum thermal expansion is 0.36 for 1.5 meter of profile. During winter the maximum thermal expansion is . 9mmfor 1 .5meterof profile.
