Having recently moved into a new build apartment, the noise through the
trickle vents in the bedroom window is driving me mad. Ironically, the
spare bedroom (which faces a railway line) has acoustic vents through
the wall rather than trickle vents through the window frames and it is
*much* quieter than the master bed where the trickle vents (even when
closed) let in way too much noise from the nearby road and passers by.

I have been trying to find some sort of acoustic trickle vent to
replace them with but thus far have only found the DN range from
Greenwood
(http://www.greenwood.co.uk/data/DN%2...ta%20sheet.pdf) which
unfortunately doesn't come in the size I need.

Can anyone suggest any others?

thanks,

David

Just to mention that ventilation without transmitting noise *can* be done.
I was once involved with a 1 ft sq ventilation duct built like a car or gun
silencer http://www.kwik-fit.com/how-exhausts-work.asp. It reduced the
noise level from well over 100db inside to maybe 50db outside, a public
space. Hate to think how much that cost.

Maybe a large bore gun silencer would work, or I found this
http://lanephillips.net/projects/silencer/
which would probably work, if made out of durable materials.

.Fill 'em up with squirty foam, and just remember to open the window for
a few minutes every morning to let the bed air.

Thought of that one already but I'd like a less severe solution! I
tried filling them with normal foam and it helped a bit- maybe I just
need better quality.

Surely there must be something on the market other than greenland for
this!

I will be speccing some windows soon for a new extension.
Is it true that if I have windows that can be locked slightly open,
then I don't have to have these type of trickle vents, that let noise
through ?

Yes! Normal double glazed windows have the *facility* to be locked totally
closed or slightly open. IMO much better than trickle vents.

I'm not so sure. ISTM that on ground floor windows locked slightly open
is akin to a notice saying "insert crowbar here".

I agree, not the best for security.
But the point is just to get the BCO satisified with the required area
of trickle ventilation per window without a huge air brick in the wall.
If I want ventilation in reality I am must more likely to open a single
high-up window that go round opening all the windows to the vent
position !
One of the advantages of double glazing (although not optimized for
this) is sound insulation. So the "hole in frame" types of vents are
not for me. Plus they make PVCu windows even more ugly.
Cheers all,
Simon.

I would've thought it'd be just as easy getting a crowbar underneath
even a closed UPVC window frame - they're not the stiffest of
structures and indeed what with the rubber sealing strips there's
probably enough of an available gap to get the bar into without causing
distortion anyway.

I'm sure one of the main reasons behind multi-point locks on UPVC
doors/windows is simply because without them the structure as a whole
would be trivially easy to get into.

Ah well..I was advised yes, BCO number one said 'OK upstairs but
security dwnstairs may be an issue' BCO no 2 said 'illegal'

Haven't fought that one put with him yet..

OTOH once the BCO has effed off, an airbrick is easy enough to get rid
of..vents in windows are not.

I believe so. The windows I've had fitted recently are certainly like this.


Doesn't this change shortly (April??)(for new builds at least), requiring
trickle vents.

I do not believe there is or ever will be any requiremnt for tfkle
bvents IN WINDOWS, per se.

The requirement is for secure background ventilation.

You can have a 4" stove pipe to the roof as far as I can tell, and it
counts..

A crowbar used on mine will *not* gain entry to the house. Six locking
points into steel tube reinforcements in the frame. The window itself also
has steel tube reinforcement

Yes! Normal double glazed windows have the *facility* to be locked totally
closed or slightly open. IMO much better than trickle vents.

That's what we had in our last place. Much better than trickle vents
from a noise point of view, also give you more ventilation when "open".
Not so good for security though, unless on an extremely small, high up
window and you lock them and any other opening panes with a key.

On some models the properly locked position is metal-on-metal, the
draught position is metal-on-plastic.

On my windows the draught position locking is metal on metal, with the same
strength as the fully locked position. Which was an important point in
the choice.
