My bungalow has the standard wall/cavity ventilation blocks
strategically placed in the walls. Trouble is that one of these is
about 5 feet off the ground and doesn't even have any hooded cover on
it, so whenever the wind blows very strongly from the right direction
and it's raining, rain is blown straight into the cavity. This is of
course a bad thing, but thankfully the wind doesn't often blow
strongly enough from the relevant direction.

Should I just get a 'hooded'/slatted cover and install it over the
existing slotted ventilation 'brick' ?

Also, opposite this on the inside wall (the room is the lounge) there
is a slatted plastic cover - the previous owner had put a layer of
corrugated cardboard (!!!!!) inside this cover in an attempt to
prevent outside sound from getting into the room. A piece of cardboard
isn't particurlarly effective though as I'm sure you'll agree! So is
there anything better that I can use for good sound-proofing, or
should I just properly block off the 'inner' ventilation slot? After
all, surely it's not needed just so long as the ventilation gets to
the cavity via the *outside* vent?

Thanks

Got a decorative gas fire have you?

No, no gas at all. Why do you ask ?

You dont ventilate cavities (ususaly) your air-brick is to ventilate
the room and probably has a duct through the cavity. If its giving
noise problems and you dont have a fire in the room I'd brick it up.
This may increase condensation but combat that with extractors in the
bathroom and kitchen.

Doesn't seem to have a duct as such, just bare brickwork.

Sounds like a good plan, thanks.

Here's a thought - would filling it up with some of that expanding
foam be suffucient, ie would that provide an effective noise block
similar to bricks ?

Correction - yes it does.

The vents are actually intended to ventilate the under floor area
rather than the cavity which is why you have similar vents in the inner
skin, presumably you have suspended ground floors, in fact I presume
from the fact that you have a vent/vents high up that you maybe live
on a sloping site and might have a fairly large underfloor void. You
obviously shouldn't block off the vents
as they are necessary to vent this void.

It doesn't sound like a cavity (which these days should be unventilated) or
underfloor vent. Is it ventilation for a fuel burning appliance. If so it
must be left. (BG monstrosities excepted).

That's the thing though, we don't have any fuel burning appliances in
that room. There's an oil boiler in another room, but that's adequated
ventilated anyhow so no problem there.

Judging by the effort it too me to remove the cardboard backed inner
grille (completely sealed around the edges with a thick layer of
paint) it had been blocked for some years anyhow from an airflow point
of view.

There is no gas mains near the property so it's never been on gas, so
I'm left wondering why the vent was put there in the first place as
it's obviously not served any useful purpose for years now.

Bearing in mind all the above, presumably that means it's safe to
block it up?

(There's an unused fireplace (and hence a chimney) in the room so that
helps from a general ventilation/moisture point of view).

A brick and some sand and cement around it would be better and
cheaper. You'll end up using your hand as a trowel so wear some latex
gloves to avoid drying the skin.

Will do, thanks for the advice.
