GALEBREAKER HAS launched a new Variable Ventilation System, an opening ventilation and weather protection screen ensuring maximum ventilation and minimum draught.

A single VVS can operate on buildings up to 60m long, says the company.

Control options allow wind, rain and/or temperature to manage the desired level of protection and ventilation.

The VVS costs from about £1800 (01594 454 600; fax 01594 544 141).
