A quality approach and brand recognition play a prominent role in today's competition. The continuous improvement of quality and its provable control guarantees a company's turnover which is necessary to survive in a difficult market.

It is only when all preconditions within a company are fulfilled that the quality standard demanded by the customer can be obtained. This standard is documented by the RAL quality assurance (Deutsches Institut für Gütesicherung und Kennzeichnung e. V.) which developed into a benchmark and an independent valuation basis for customers to decide on their choice of windows and doors.

Guaranteed advantages offered by RAL-approved windows and doors:

• Consistent quality, applicable to all frame materials, possible sizes and designs
• Long lifespan of windows and consequently a favourable cost/benefit ratio
• Low maintenance
• Environmental aspects are taken into account
• Professional attachment to the solidium

The Gütegemeinschaft Kunststoff-Fensterprofile awarded the mark of quality to VEKA AG for both white and coloured profile systems. These certificates ensure consistency of product quality and are therefore a prerequisite for window manufacturers to obtain the RAL mark of quality.
