uPVC Advantages

Maximum Wind Resistance : Siesto uPVC window and door systems are ideal for being installed in buildings close to the sea, where they are exposed to strong winds, heavy rain and salty water. All indows and door systems can take a wind pressure of 2400PA(appox. 230km per hr.)


Maximum Water Tightness : One of the main assets of Siesto window and door systems is their resistance to driving rain & their joint tightness. They are designed to be water tight when tested up to 300PA, limit specified in BS 3675 performance of windows part 1 1989, classification for weather tightness.


Minimal Maintenance : Siesto uPVC window and door systems do not require regular painting and expensive maintenance. They do not rot, wrap nor corrode in tropical and coastal climate. The maintenance is minimal and does not involve any further costs.


Fire Resistance : Siesto uPVC material do not support combustion, in fact they are self extinguishing. Throughout their product life, the material will not cause, support or enhance the natural development of fire. The profile compound possesses a fire retardant rating according to DIN 4102, also fulfills Class 1 fire resistance as defined in BS 476: part 7.


Longevity : Siesto uPVC profiles maintain excellent inherent material properties. The windows and doors are attractive, perfectly tight and working well even after many years in use. The longevity and superior quality of this material has been conclusively proven over 30 years.


UV Stable : Siesto uPVC windows and doors are completely UV stable. Siesto has developed its own ideal material compound, an uPVC blend especially suitable for tropical climates. The material does not alter under extreme temperatures or weathering.


Customization : Siesto uPVC window and door systems offer wide range of design combinations, which are customized to any possible dimension.

Environment Friendly : Siesto uPVC profiles are completely recyclable containing Greenline calcium zinc for eco friendliness. The energy used for extrusion process is relatively low when compared to other materials.


High Acoustic / Sound Insulation : The protection against noise is an essential characteristic of a modern window, in order to ensure a comfortable life both at home and in office.  Siesto uPVC windows and doors insulates up to 40 db which comes up to the German DIN standard for sound insulation Class 5, DIN 4109.


Thermal Insulation : Siesto uPVC profiles are multi chambered section, provided with unique double seal mechanism, multi point locking system and good combination of glass, makes the window perfectly sealed and thereby reduces energy loss.


Energy Efficient : Siesto uPVC window and door systems are excellent thermal insulators. It can save energy up to 40% of energy requirement.


Impact Resistance : Siesto uPVC profiles are of highest impact resistance grade, which exceeds the stringent requirements to the highest classification of DIN 53453/ ISO 179 standards for impact resistance.
