The international market of construction materials has become increasingly dynamic in recent years, including as a result of the introduction of European conformity marking (CE), which encouraged the technical progress and implementation of innovations. In this overall context, the windows and doors witnessed an unprecedented technological  "boom", especially in Germany - a country well known for reliability and functionality of the promoted products. The demand for high-performance solutions remained at a high level even in times of economic crisis, despite their increased costs. Given the continuous tightening of regulatory requirements, promoted models are permanently improved to adapt to the new technical and aesthetic trends. As regards energy efficiency and - more broadly - the concept of sustainability, are already visible changes imposed by legislation, including in the field of doors and gates. Nowadays, urbanization exerts a direct influence on the profile market. In many countries in Central and Western Europe, including Germany, energy-saving regulations were tightened and demand for subsidies for the implementation of specific measures to streamline the existing buildings has multiplied exponentially. In the plane doors field and the one related to the materials used in their manufacture, the immediate effect was the limitation of heat transfer coefficient. Regardless of position on the specific market (as system providers, manufacturers, specialized or general contractors), companies must dynamically adapt to these requirements, dealing - mainly - with sustainability, accessibility, competitiveness in prices, adaptability to new features of living space etc. One of the most important catalysts consists precisely of demographic change and accelerated urbanization, manifested in more and more regions of the world, including in countries with emerging economies, which until recently, didn't matter in global supply and demand equation.
