Ventilation

VELFAC Windows offer the opportunity to control natural ventilation in many ways.

Simple manual opening windows or trickle vents, to computer controlled electric actuator operated windows, or smoke-vents.  We can also provide acoustically attenuated trickle vents for facades overlooking busy roads or railway lines, which would be used in combination with specialist acoustic glazing.

Open windows in black frames causes good ventilation

VELFAC consultants can advise on different window configurations to maximise ventilation capacity, and carry out opening area calculations to assist specifiers in designing ventilation strategies.
