    We built our first lehrs in 1957 to respond to the demands of the hollow glass industry. A few years later we introduced the concept of a steel construction for flat and float glass production. This resulted in a spectacular increase of the yield in comparison to brick annealing lehrs. From its early collaboration with Pilkington in the design of the tin bath roof Cnud-Efco has worked tirelessly to ensure that the high standards set by the Pilkington pioneers are still maintained today. Over 300 annealing lehrs and roof installations have been put into service worldwide.
