Clement Windows' EB20 Range

The EB20 Range of Steel Windows

The EB20 range of steel windows, made only by Clement, has been designed to meet the demands of projects where a particular steel window look is required. Made to suit the individual requirements of each project, the EB20 steel window range is a versatile solution for a number of commercial projects.

Clement EB20 windows have been created for fenestration projects where a traditional steel window appearance is required, replicating the appearance of original or existing windows while simultaneously providing all the advantages of 21st century technology, including enhanced security and energy efficiency.

EB20 windows are manufactured with exceptionally slender frames. The 20mm insulated glass units mean that the largest possible glazed area is provided, thereby optimising solar gain and saving energy through reduced use of artificial lighting. A most versatile and popular product, EB20 windows are appropriate for both refurbishment and new build projects. The 20mm glass offers an increased ‘shadow line’ which is preferred for many heritage projects.
