Optimize Energy Efficiency with High Performance Openings /Other/Ceco/Images/large%20project%20photos/frost.jpg Ceco Door energy efficient solutions include thermal break frames and weather-stripped (kerf) frames that help prevent drafts and eliminate frost build up. Doors with polyurethane cores provide exceptional thermal resistance and total surface support for impact resistance. Combine these products for weatherized solutions that will help protect the contents of the building and save on energy costs as well. With more focus on the need to provide energy efficient openings Ceco Door is testing products to the most current test standards including, ASTM C1363 (thermal transmittance) and ASTM E283 (air infiltration). These tests include other ASSA ABLOY Group hardware products to give building owners a better indication of actual thermal performance.
