English to Russian Marketing Engineering (general) Window Protection Systems

The first louvres were designed to allow the passage of the sounds of
bells and chimes whilst protecting the bell tower from rain.
Today, louvres have evolved to be able to help protect against noise,
rain, birds, vermin and in some cases air! In other cases louvres have
been designed to explicitly allow the passage of air.
Many options including the incorporation of access doors and hatches
can be achieved in one homogeneous façade with the XXX
continuous louvres system.
