Tradition in window and door construction – eyes on the future
Production
At Carl Wilhelm Cleff GmbH & Co. KG we look back on a long tradition in window and door construction without losing sight of the future. We proactively take up the constantly changing requirements of the most diverse operating conditions and develop products that meet our customers' wishes.
Technologies
Technological progress is always at the forefront of the development and manufacture of our products. Accordingly, we invest sustainably in know-how, production facilities and up-to-date processes in order to offer our customers state-of-the-art products at market prices. We therefore attach great importance to testing and optimising new and modified processes for reliability before series use.
Development
“Good” design remains the key to joint success. We attach great importance to ensuring that, already in the quotation phase, the combination of experience in production, quality assurance and product development results in the “right solution” – and that this is consistently continued in the subsequent design phase. Only the professionalism and long-standing interplay of all departments involved produce a high-quality final design.
Quality management
Against the background of constantly changing conditions, the regular review of our business processes is an essential part of ensuring the consistent quality of our products – and ultimately the continued existence of our company. We therefore subject the sensitive manufacturing steps of bonding, welding and decorative surfaces in particular to regular audits by external bodies with an “outside view”. Their certificates prove the excellence of our processes and give our customers additional security and confidence.
