Window Cill Specifications

Our three standard designs suit one or two-brick course heights in a normal cavity-wall situation. They are available in the following lengths to suit British Standard brick openings.

Note: Dimensions exclude stooling – maximum 100mm (315⁄16”) at each end.

• Only supplied as a two-piece sill.
• One-piece only when supplied without stools.

Please note that other sill sizes can be manufactured to order.

We strongly recommend that you refer to Eurocode 6 and PD 6697: 2010, and our Tech Sheet M90/TS for installation recommendations.
