Loft Ventilation

[sparko]

Hi guys and girls

Just wondering if anyone knows how to get the circulation to come in at the front bottom of my loft and out the rear top above the false roof inside ,ive noticed the wind does seem to hit the back of the loft alot and so it comes in and pushes the air down rather than it being drawn up and out also i dont want the louvers at the back on the bottom as im building a breeding section there and its also a very cold easterly wind too ,so is there some sort of build that would make the air go out the back even if the wind is hitting it ? at the moment its a 2 inch gap running the full length underside of roof facing the floor similar to the front but not as wide.im also going to put bigger louvers in the front and one on each side all at floor level.

Easy bring the fresh air in at the back and out the front pal

does it not matter which way the air goes out as i thought the stale air which rises would just be getting blown back in the loft with the air coming in from the rear top ? and going down into the birds section ?

[geordie1234]

No it does not....as long as stale air leaves the loft your fine pal

Thanks Geordie thats put my mind at ease trying to think of a design that would draw the air out even if the winds hitting it

well im almost bald myself hahahha i think it is worrying about the birds ive got in the loft trying to give them the best i can as ive only got 8 latebreds from good stock from england that i need to keep healthy to build my team with next season so i have something different to what most have here in iceland.

Just to put a spanner in the works, I was at a Pigeon moot a few weeks ago when 2 of Scotlands best fanciers were on the panel one a double National winner , and both stated that ventilation is not important in fact both wanted as much heat in their loft as possible.not my views but theirs.

The main points of ventilation is having a continuous air exchange while avoiding a draft, the acid test is on a day with little wind, if you can smell the pigeons on entering the loft then the ventilation isn't perfect, so if your loft has no odour's from the birds or their droppings and the birds aren't sitting in a draft then you will be fine.

Remember even the best vented loft will fail if it's over crowded so their are other factors to good health.

And yes heat helps but you have plenty of sun light getting in so this shouldn't be an issue, nice loft good luck.

Try blocking off 50% of the vents at the back. What you need to achieve is for fresh air to enter through the vents at the front of your loft. The way your loft is set up is on a day with no wind air will exit from the front top, it's being encouraged to do so by your false ceiling covering the back portion of your loft also the highest point being at the front. Warm air will rise carrying the stale air with it and left to its own devices will exit from the highest point. Its going to be a job and a half to resolve this issue and my guess is the amount of pigeons you house will be the deciding factor.

Purchase some Pronavit Smoke Bombs Pal ! (3 for £10) Place one in your loft (Read instructions) And light It !(Best on a calmish day with a slight breeze)stand outside your loft and watch how the Smoke behaves ! IE-Where it is exiting your loft the most and how quickly ! If your not happy then you can adjust/tinker with your ventilation abit ! Also good for clearing any lice/mite and other creepys out yer loft !!

Your false celling is covering too much as the hot air rises its prob heading back out the front if you can bring it back by half it should help

 

In the main the highest spot should be at the back of your loft as the hot air rises that where it will head too

 

If u can smell birds its just not right I personally don't like air coming in from the bottom

 

Dont worry about air getting in as it will always be replaced its more important on how it exits a loft

Thanks for the response guys ,its been a calm day today here and the only thing i could smell was the smell of new wood so i guess im ok at the moment but i only have 8 birds in it and the max i will have is about 38 young birds when the loft is full which is about 14ft by 8ft.again thank you its very much appreciated

Very good point

I have built many lofts for national and multi national winners

Not a single one had ventilation entering at low level

Food for thought

does that mean there isnt any louvers at the bottom ? just in one side at top and out the other or entering the top and out the bottom ?please clarify this for me

Looking at your loft the problem I see is the overhang or should I say lack of it both front and back

Appreciate where you live you will experience severe weather on occasions but if roof is properly bolted to structure and secured to base all should be ok

At least 12 inches front and back with 1/2 square mesh frame fitted to underside thus preventing vermin from entering

Would also have liked the overhang projecting at sides giving protection from rain

You have the perfect loft to create a ventury ventilation system where all you require is to put a vent on the front of the loft. The system works thus, Air will blow through either the front or back at roof level sucking air through the bottom louvres and up through the false ceiling taking with it dust as well as stale air into the ventury you have created and exit it all through the down-wind exiting louvre as you have created a vacuum "suction"..You can even shut the bottom louvres off if you feel their is too much air coming into the loft.

Why fit louvres to bottom if you were then going to close them

Only a source for draughts ?

However everyone to there own
