Fabricated Doors and Windows


Developed in Germany, the concept of passive housing is based on various methods and technologies to reduce the heating and cooling consumption of a building. Based on the principles of using very high quality materials and unique avant-garde systems to achieve complete insulation and maximum waterproofing, this type of construction promises unparalleled comfort to its occupants while reducing costs related to energy consumption. NZP Fenestration and its experienced team are constantly working to expand their knowledge and suggest emerging technologies that not only respect the environment, but save you money.

Net Zero

The principle of the net-zero energy house is based on the concept of producing more energy than it consumes. Combining several systems producing clean and renewable energy (thermal and photovoltaic solar panels, geothermal, wind, solar water heaters, etc.), this radically limits greenhouse gas emissions, making your home an eco-friendly home. Thanks to the high efficiency of our doors and windows, you will be able to be part of the ecological community and promote the emergence of healthy and sustainable homes by contributing not only to your own comfort, but to the well-being of our planet.
