Examples of mullion

mullion
The intermediate mullion acts as a tension strut tying the two planes together.
Further, the mullions were referred to as 'being 2in thick plywood with some thickening at the edge'.
The mullions were later changed to aluminium as a cost saving.
This change appears to have been a result of the increase in depth of the mullions from 600mm to 1 metre (2ft to 3ft 4ms).
The landscape horizon, echoed with a horizontal window mullion, reinforces the library floor plane.
Its gothic fantasy is framed by ferns, with the plants growing through unglazed mullions.
The whole is crowned with a striking roof canopy standing on slender mullions.
The standards were insulated internally with wooden cover strips to reduce cold bridging, and the external clear glass was glazed in a system of light timber mullions and transoms.
Meanwhile, mock-ups of the minor hall ceiling and mullions were commenced and issues of preservative treatment of the plywood and design of the ceiling suspension system considered.
Shadows catch in the delicate mullions and articulate the border between interior and exterior space.
The detailing, for example in the projecting window mullions on the end elevations, with the corner mullions set on the diagonal, is bold and simple, exploiting its texture.
I understand that, of the more than £102 million on offer in the current pay round, £40 mullion is covered by the planned productivity increases next year.
