I purchased a small airconditioner - http://www.johnlewis.com/230396426/Product.aspx

The problem is that I need it to vent out of a glass window - a
glazier has done this for me, he's attached the vent (which is a cover
for the hose) to a sealed hole in the window, with a cap to cover.

However, this isn't really ideal, as it essentially gives a passage
into my house for people to put things through....!

I'd much prefer a vent such as http://www.toolstation.com/images/li...bbig/69921.jpg

The problem is, I cannot find anything like this suitable for a window
- everything is built for walls.

Is anyone aware of a 'flap' type vent, suitable for sticking into a
window? The hose is 130mm

Many thanks

Joe
