Trickle Vent - Correct Sizes

Al Capwned

Hi Lads,

Have looked through a few threads and cant find anything specific on what I'm Looking for - *wonders how long it'll take my inept search to be pointed out*

Apart from the extractor in the kitchen, there are no vents in my mates house - anywhere.

Now he is reluctant to drill new vents into the walls (dont know why) and is insisting on retro-fitting trickle vents like the ones in the pic. Now I've fitted these before, and they are relatively straight forward to do, but my question is -

I seem to remember there being a certain area of vent being required (so many square mm per cubic m of room space) but I have no idea where I read this, and my mate is adamant that we find out this information before i lift a drill..... So I was hoping one of the good folks in here might enlighten me.

Any help or advice appreciated. Thanks.

He's dead right... there a much better job and more controllable.. IMHO the wall vents should be done away with and these trickle vents become the norm

Not sure if it's still the same but Sinnerboy stated at the time:

"It depends on the number and type of trickle vents you have installed .

6500mm2* is required per habitable room - it is possible - but you need to check carefully

* more in kitchens / bathrooms"

Are trickle vents successful and trouble free when fitted to existing white pvc windows? What size and quality is recommended. Do they give trouble down the way?

3. What size and quality is recommended.
4. Do they give trouble down the way?

1. define successful. this is a requirement for ventilation yes? if the house is fairly air-tight what about mechanical ventilation?
2. depends who fits them and what type you get, have had clients complain in the past. remember your fitting a vent to an existing window so no one will take responsibility if something goes wrong.
3. room size dependant. see http://www.environ.ie/en/Publications/DevelopmentandHousing/BuildingStandards/FileDownLoad,1647,en.pdf read section 1.2.2
4. as per no.2

I really appreciate what you say re above. Can you recommend any particular type that you feel are trouble free. What sales rep has suggested to me is obviously very cheap and the cost is in the labour. If you prefer send me a pm. tks again

Hi did you get trickle vents? I need to do this too! Any advice / guidance really appreciated

Hi,

No I didn't go ahead with trickle vents in existing PVC windows as I was advised that to do so might cancel any guarantee on them. I was most unhappy about going ahead with this as I felt most of the cost related to labour and can be a bit unsightly.. I changed my insulation company who didn't require this as they maintained we already had good ventilation in the house. We did put in a vent in the wall of the room with a fireplace which can be opened and closed by a sort of plate. It was a little more costly than a grid but very neat. The BER inspector was quite satisfied with the result. Hope this helps!

There is no brand name on the vent that I can see but on the inside(room side) it is very neat with a circular cover that spins around to open and close easily The hole in the wall is lined with a metal tube from inside to the exit which is a simple grid. No need to block out the cold in winter as it can be closed off or opened as required. The insulation company supplied it.
