Handels- en Constructiebedrijf H. Hardeman B.V.

Hardeman Kozijnen is part of Hardeman Veenendaal, a family business with extensive experience in the construction world. The production of the plastic frames takes place in our own factory in Veenendaal, which means that we deliver these frames with the quality and service you are used to from us.

We produce high-quality windows in the Gealan S9000 system.

The Gealan S9000 system has been specially designed for the requirements and needs of the Dutch market, so it meets all visual criteria.

A suitable type for every style

Thanks to the 3-seal system - and in particular due to the innovative flexible centre seal - these windows achieve the best performance and values in terms of thermal insulation and wind and watertightness. Thanks to the raised rebate, better insulation is available and the frames easily meet the burglar resistance of SGK class 2. The S9000 NL system is therefore suitable for windows and doors at the highest level.

At Hardeman we make 2 types of the Gealan S9000 system, the S9000 NL, a slim, traditional frame with depth effect due to the 15 degree sloping, and the S9000 slim, with a shallow installation depth which is perfect for sleek, modern facades.

Both types of frames can be optionally designed for use with a glass thickness of 26 or 44 mm. For both types we have selected 4 colors in which we can produce faster through our own stock. In addition, there are 17 other colors to choose from!
