All our windows are "Tilt-Turn-Vent" (minimum size required). All windows open towards you rather than away from you as many older conventional windows do. This allows you to keep your house secure while ventilating the room if the need arises and is convenient for a number of reasons as:
a) higher security,
b) ease of cleaning,
c) insects guard/screen can be placed outside,
d) keeping windows open during rain (Tilt mode)
e) micro-ventilation
Avante's unique uPVC windows offer a great insulating, energy saving performance, U values, and an unique Tilt-Turn-Vent technology. This special opening micro-ventilation mode sets the window with a 5-8 mm ventilation gap from the frame. This mode allows the air to be exchanged without actual opening the window and loosing any security.
Great range of modern Energy Saving windows suitable for all types of homes including Passive Houses and New Builds. Avante uPVC energy saving windows will keep your house airtight with no drafts and no energy loss. Loosing energy is loosing money and leaving an unnecessary carbon footprint.
