How does a casement window differ from a sliding window?

The AIW C28 uses a double-leaf design, so the view is not divided by frames, and it guides airflow indoors for ventilation. It matches the slider on performance: the highest national air-tightness grade, average water tightness of 2000 Pa and STC 36 dB sound insulation.

What are the water tightness and wind load figures?

Average water tightness of 2000 Pa with a maximum of 2750 Pa, wind load resistance of 5000 Pa, and the highest national grade for air tightness.

How does it perform on sound?

STC 36 dB with 10 mm glass. Automotive-grade seals improve both sound and water tightness, and 5 mm + 5 mm insulated Low-E glass is fitted as standard.

Is it safe to open with children at home?

An opening limiter provides double safety by restricting how far the sash can open.

Is it heavy to push open and pull shut?

Heavy-duty four-bar hinges keep the movement smooth, and an anti-sag roller mechanism makes it easy to open and resists sagging over years of use.
