New Age Material
uPVC is the new age material and choice of modern homes and workplaces. It is slowly replacing traditional window and door materials; Wood and Aluminum. They have come as a solution to many disadvantages posed by wooden and aluminum products like high maintenance, wear and tear, reaction to change in climatic conditions and inability to provide sturdy large windows.
Polyvinyl Chloride (PVC) was discovered completely by accident independently by 2 Scientist. It was first discovered by French chemist Henri Victor Renault (Year 1835) and by German Eugen Baumann (Year 1872). The un-plasticized form of PVC, known as uPVC eventually found a use as a building material in Germany and then its usage was quickly spread to other countries as well due to its varied properties.
Potential of using uPVC as building material attracted R &D of the material. Ability to cast them as Profiles opened up and making them sturdy by reinforced by steel or aluminum revolutionized its usage as new age building material making it robust, firm, thermal insulate and durable.
uPVC material have thus become the choice of architects as it allows them to be creative in the shape, size and colour of the windows and doors. . Modular designs can be created using seamless combinations of sliders, casement and fixed windows. Cost effective production of uPVC material has made bays, arches, tilt & turn and combination windows, vertical, horizontal, trapezoidal windows affordable to even middle class households Reach out to Deltra to find out more and find solution to your uPVC Window & Door needs .
