Energy efficiency continues to grow in importance — and rightly so, in our opinion. That’s why, for many years, we’ve focused on multiple all-around sealing levels in the development of our doors. Only a truly airtight door protects you from cold and noise, reduces heating costs in winter, and supports energy-efficient living through smart design. To help you improve your home’s energy performance, the KfW offers financial subsidies for renovation measures.
Powder coating, known for its aesthetic and environmentally friendly properties, increasingly focuses on sustainability. By integrating heat recovery systems, the heat generated during the coating process is captured and fed back into production. At the same time, water is purified through evaporation and reused in a closed-loop system. These sustainable practices not only reduce energy consumption but also minimize water usage, enhance resource efficiency, and contribute to environmentally responsible production processes.
Groke aluminum entrance doors stand for quality, modern design, and high security – and they meet the requirements of the QNG seal for sustainable building. This makes them an active contributor to environmentally conscious construction.
The QNG seal, issued by the German Federal Ministry for Housing, Urban Development and Building, is a prerequisite for the Federal Funding for Efficient Buildings (BEG) program and certifies ecological, economic, and social sustainability.
Advantages of QNG-compliant Groke entrance doors:
Planners, architects, and builders can thus specifically focus on eligibility for funding and sustainability.
Sustainable building begins at the front door – with Groke.
The new Environmental Product Declaration (EPD) for aluminum exterior doors by Groke Türen GmbH documents all relevant environmental impacts throughout the entire life cycle – from raw material extraction to disposal.
The document is based on the standards EN ISO 14025 and EN 15804+A2 and has been reviewed and verified by ift Rosenheim.
