Application

EB20 windows are appropriate for both new build and refurbishment projects.

Description

The Clement EB20 windows have been created for projects where a traditional steel window appearance is required, the EB20 range is designed to replicate the appearance of original or existing windows while simultaneously providing all the advantages of 21st century technology: first rate thermal and weather performance, low maintenance and high security.


EB20 windows are manufactured from recycled steel and all the windows in this range have exceptionally slim frames. The 20 mm insulated glass units mean that the largest possible glazed area is provided, thereby optimizing solar gain and saving energy through reduced use of artificial lighting, making this one of our most efficient windows. The 20 mm glass offers an increased ‘shadow line’ which is essential to many heritage projects.


Frames are manufactured from hot rolled carbon steel profiles with corner joints mitred, welded and dressed square and T glazing bars whose ends are tenon riveted and/or welded the and cross joints are interlocked and welded with rigid joints. Composite windows can be assembled by connecting windows horizontally and/or vertically with mullions and/or transoms of hot rolled slim steel profiles. Box sections are available as tubes or as box mullions which can be either hot rolled or manufactured from sheet steel. Pressed metal cills are available in a choice of profiles. Trickle vents can be fitted in accordance with Building Regulations Approved Document F.



Features and benefits:

  • Exceptionally slim 20 mm insulated glass units
  • Building Regulations Approved Document L compliant
  • Window Energy Rating of 'B' available if greater thermal performance required
  • Available with multi point locking to PAS 24 or traditional single point locking
  • Low maintenance
  • Various glazing options.

Manufacturer guidance

EB20 windows are double glazed with high performance 20 mm insulating glass units. The specification includes the latest glazing technology, a 4 mm inner pane, 12 mm cavity with krypton gas fill and a 4 mm outer pane. This configuration achieves a superior performance with a centre pane U-value of 1.1 W/m²K. The panes are joined using special Warm Edge spacers.


In accordance with Glass & Glazing Federation best practice, Clement steel windows are generally factory glazed, however, our concealed fixings mean that fixed light windows need to be glazed on site after the frames have been installed. Glazing beads are made of aluminium.


EB20 windows can be supplied with semi, round or gothic style heads, and ‘curved on plan’.
