Right protection for windows vital

The use of plastic to protect windows of important buildings, such as the City Hall in Belfast, from the weather and vandalism was abandoned many years ago (News, May 27). Ventilated glazing to an approved specification has been the way forward ever since.

However, if a decision has been taken to use acrylic plastic, then it should be of the cast variety – not extruded – and ventilated all around.

There is no point in treating this installation as a temporary measure that will go up and down as required at great cost.

Better to make it a permanent feature, following a specification that will not disfigure the building.
