Never bettered in 50 years. Fab invention.
on 10 September 2012
These really work and do the job. Just had some 5" and 7.5" added to the House. Have had some for 10 years.
A great simple product that actively ventilates without any security problems.
No windows to be left open. No security problems now.
NB larger size is preferable if not in your face. 90% more air! Lots of air! A lot more air than Trickle Vents.
I have small panes of glass 8.5" wide so glazier fitted it to a new glass and then
put this in. Fitting it to an existing pane would likely crack glass.
(Also available vents for double glazing. You need to buy a new DG window pane and the DG factory fits it.(
Problem is they get dirty and after 2-3 years its difficult to unscrew for cleaning. They can look very naff but at the back of a house who cares?
So leave them or replace. They look great new.
Also spinning piece can break off after a few years... not a big deal for the price. Just replace! They still work. I have never used the Stormguard. APPARENTLY IT DOES NOT Keep dirt away or stop spinner breaking.
