About us

The Geplast Group began manufacturing modern PVC, Aluminum and Aluminum Clad Wood windows at the end of 2007 in Poland. At the beginning we’ve been suppling residential and commercial developers throughout country and steadily building up our production lines, increasing production capacity and product assortment to begin exporting 5 years later to countries in European Union such as Germany, UK, Italy, Croatia, and other. In 2020 we opened our first distribution office in North America supplying our products to Chicago and its Metropolitan Area and at the beginning of 2022 we took another step forward and began to set up distribution in Canada through Montreal and Toronto.

The main aim of the company's activity is the manufacturing and export of modern, high quality PVC and aluminum/aluminum clad windows and doors in vast choice of styles, finishes and colors.

We offer certified Passive House windows which provide outstanding, industry leading performances. They can be characterized by having superb thermal break, being airtight, triple glazed with the gaps between glass panes filled with argon or krypton gas.

In general, European standards surpass North American in regards to passive windows and its performances. That’s why our windows offer high R-value, low U-value (0.14 or less) to maximize solar gains (in cold climates) and minimize heat loss/gain through glass to provide excellent insulating properties. To have a certified passive house, the building’s overall energy use and air leakage are the deciding factors and our windows provide just that:

 Uw-value < 0.14
 High R-value
 Triple Glazing
 Frame usually PVC or AluClad
 No thermal bridges
 Airtight
 Excellent solar energy transmittance
