Star Boya ve Kimya San. ve Tic. Ltd. Şti.

Founded in 1989, Isoweir initially specialized in the production and sale of industrial and construction paints, auxiliary materials, marine coatings, lacquers, and thinners for the leather industry. In 1995, the company completed R&D on water-based carton inks and flexo inks, introducing new formulations to the market and securing its position in the industry.

With the growing significance of water and thermal insulation due to climate change and rising energy costs, Isoweir focused its R&D efforts in this field starting in 2001. In 2002, it launched the patented Isoweir Insulation Plaster and Isoweir External Insulation System, offering a lightweight, dowel-free solution that provides 100% waterproofing. During the same period, Isoweir Roof System was developed, delivering a monoblock roofing solution that combines aesthetics with superior insulation performance.

In 2005, the company introduced Isoweir Foundation Insulation, a cement- and sand-free plaster formula that ensures monoblock, impact-resistant foundation insulation with 100% waterproofing. All insulation products are developed through in-house R&D, protected by patents, and manufactured under strict quality control.

In 2010, Isoweir Thermo Plaster was launched, providing a lighter, more economical solution for high-performance thermal insulation. Today, Isoweir stands as an industry leader in producing innovative solutions for roofs, facades, and foundations, with a strong commitment to research, patented products, and sustainable construction practices.
