The company aluplast was founded in 1982 by Manfred J. Seitz. Flexibility, a fast decision-making process, great emphasis on an ideal cooperation and offering market-ready and appropriate products enable aluplast to meet global requirements. From reasonable prices to exclusive high-value solutions, the system provider sets its value on the market needs.

Up to the present, the company has been remained to be a family owned company and is being managed by the founder’s sons Dirk and Patrick Seitz

Today, aluplast with its high-quality window solutions is known as the technology leader in the branch, presenting at least one brilliant innovation every year. This also applies to aluplast’s latest development: energeto®, an energy-efficient window frame profile with metal-free thermoplastic reinforcements.

This patented and highly awarded window system is developed by aluplast and our partner BASF – the chemical company. energeto® allows the production of a window system both thermally insulating and economical at the same time without the need of steel reinforcements, which was impossible prior to that. A unique thermal insulation of up to Uw = 0.60 w/m²K can be achieved by using energeto®.

Over the past decades, the company has been developing a worldwide network of more than twenty production and sale subsidiaries. Day by day, the uPVC window system provider ensures quality and best technical support to our partner, worldwide.
