In response to the need of use of up-to-date technology and best use of recent scientific and industrial products in civil constructions, ''Sayeh Saz Ieman Co.,Ltd.'' has been established in 1995. This company was founded in order to present new and useful products to construction and related industries and in its first steps towards this goal, it presented transparent and safe ''Lexan Polycarbonate Sheets'' on the market. After succeeding in presenting Lexan sheets and all related products, ''Sayeh Saz Ieman Co.,Ltd.'' began to do some researches on another constructive product called Window Film and now presents "LLumar Window Film" in Iran.

For the immense and complicated scientific information of the mentioned products, ''Sayeh Saz Ieman Co.,Ltd.'' has made use of professional scientists in order to present these products as good as possible. According to the need for following the standards in usage of these products, this company has made it possible to execute numerous projects by using a group of experts.

In the near future, ''Sayeh Saz Ieman Co.,Ltd.'' is going to present products such as "PolyU Polycarbonate Sheets'' and ''Plexiglas Sheets'' on Iran’s market and hopes to have significant effects on improvement of domestic projects quality.

Lexan polycarbonate sheets are special products among engineering thermoplastic types. Lexan’s high quality has made it an ideal material for every transparent sheets use. Lexan polycarbonate sheet is the hardest and the most resistant transparent material ever presented on the market. In addition to the important quality of unbreakability, it has provided features such as: light weight, fire resistance, color constancy, heat and sound insulation.

Besides general features mentioned above, other particular features of Lexan polycarbonate sheets will be very useful in specific projects, these features include: chemical resistance, volume resistivity, compatibility for designing light resistant structures, variety in colors, simple cut and installation, UV protection ( Ultra violet ), usage capability between temperatures of 40cº and 120cº, perfect dielectrical quality, air conditioning costs reduction ( heating & cooling ), high resistance against unexpected events like earthquake or storms or inappropriate weather conditions.

LLumar window film is a thin layer, composed of a number of polymer layers. LLumar thickness varies between 0.035 millimeter and 0.4 millimeter (400 micron) in different kinds. Each one of the layers in window film is designed for a particular purpose. Then the layers are combined with each other and they form a united product so that once combined, separating them would be actually impossible.

The growing need to use glass in civil constructions, industries and cars has always been challenging the numerous disadvantages of glass. For instance we can mention: air-conditioning energy loss, impact fragility and challenges which make it dangerous in the case of unexpected events, excessive Transmission of light and harmful sun rays. Nowadays LLumar Window Film multilayer sheet is the latest technical achievement for completing glass and tackle its drawbacks.

After many years of presentation of high-tech constructive production, and technical researches, "Sayeh Saz Ieman Co.,Ltd." has begun to introduce and present the various productions of the Italian company with the name of "PolyU".

"PolyU" industrial group was founded in 1980 and from the beginning, started producing a variety of new productions, with using Polycarbonate resin. Variety of "PolyU" has made simple design and beauty possible at the same time.

In addition to multi wall polycarbonate sheets, Polyu has produce multi wall corrugated "Thermonda" and "Thermogereca" sheets, multi wall superposed with sandwich panel sheets, for the first time.

These two products have made a great effect in developing Polycarbonate sheets industry and are used easily in installation on the roof of factories and industrial companies.

Making a transparent atmosphere in industrial roofs, besides reducing the amount of energy spent on light, plays an important role in facilitating the use of natural daylight.
