Hi, I would like info about venting the cooker hood into the loft that is fully insulated. Will it matter?

Question

It would be very difficult to vent the cooker hood to the outside of the bungalow as I would need to get into the loft and clamber all over the insulation with the inevitable compression of the insulation, whereas I could cut the necessary opening in the insulation from inside the kitchen!

Answer 1

Never vent into a loft or live to regret it. You can work in the loft if you put strong planks or floorboards to walk on. Anyway, if you stepped on the insulation, chances are you will go right through the ceiling. Cut the hole for the venting hose from the kitchen and remove the insulation from the top and pass the hose through. Cut through the wall and vent the hose to the atmosphere. Replace the insulation and you will have done it properly.

Answer 2

American answer. You never,never vent anything into the attic.

Answer 3

Not a good idea.

The cooker hood will vent all the fats and grease from cooking into the loft - this will attach itself to the insulation and it will smell after a very short period of time.

This will attract rats, mice and birds - especially Starlings - these (if they get in) will then nest and spread mites all over the house.

Not only that, but by allowing the venting into the loft and the subsequent grease and fat problems - you may even create a fire risk as the fat will burn more intensely should it ignite. Not only that but eventuall you will have to go into the loft for something or other and you will get covered in grease and insulation material - it will stick to you even more.

It will be harder in the long run to vent outside but the job will be better and safer.  

Answer 4

Also what about the smells. Surely you could remove bricks to the outside without too much of a problem and make a vent hole this way. Unless you live in a granite house like I do it ought to be an easy job. Why not just have a recirculating cooker hood with charcoal filters.

Answer 5

Don't even think of it, there is a lot of moisture from cooking, and this moisture would condense inside the loft and cause mildew and even rot.
