Cill sections

At GreconUK, we offer one of the most extensive portfolios of standard cill sections, all of which can be cast with or without stooling (slip cills). Our cills can be cast in any number of lengths, determined by the frame/opening size of your build and the subsequent choice of stooling. In addition, profiles can be cast to suit any required bay configuration.

Any one of out standard cill profiles will enhance the appearance of your build, without detracting from the vernacular appeal of the overall masonry façade. Due to the number of possible masonry wall finishes available, we would highly recommend that you consult with one of our technical sales managers in order to discuss your cill section requirements.
