Comar 2 Window Walling

Comar 2 is a comprehensive system primarily designed for use in medium rise applications and higher stairwells for new and replacement projects, but can also be used for entrance screens and shop fronts, etc.

Construction comprises a two-part channel and plate mullion clipped together to form a 100 x 45 mm or 100 x 30 mm box section, with co-ordinating 98 mm transoms, enabling a modular sash construction. All main extrusions have four screw fixing ports. Additional profiles allow for 90º and 135º returns and a range of sill sections provide drainage to the exterior.

Incorporated components:

The Comar 2 system can be used in conjunction with Comar 5 system window types and Comar 7 aluminium doors.
