Suitable Extractor fan + chipboard floors

Hi, hoping this has probably been done many times and someone will have a quick answer

I am just finishing off an extension which has left me with a bathroom in the middle of the house with no external walls, so no windows.

Can anyone suggest an extractor fan that would be suitable and upto the job of keeping the bathroom relatively dry from the steam.

Extractor will be vented through the roof

The other qestion is, are 18mm water resisitant Tongue & Cheek chipboard panels suitable for 1st flooring (especially in a shower room)

Thanks in advance for your responses

Water resistant chipboard!!. Interesting.

I after a leak or two and replaced with 18mm Marine ply flooring, will take a soaking apparently.

any tangential fan designed to be used with ducting. See screwfix or toolstation .com

4" will give you garbage flow rate, 6" has real use.

no way Jose. Use WBP ply

TLC also do a 5" wall mounted one - installed two of those in the past. The one in our shower room works like a dream - never a trace of any steam in the room (timer set to 10 minutes or so).

Thanks for the replies

Looks like my options are either 18mm wbp plywood or aqua panels over the top of the chipboard that has already been laid.

BTW, is the chipboard ok for other rooms like bedrooms, or a definite no-no and just stick to 12mm wbp plywood for these.

Thanks Gaffar

According to building regs it is:

Still, I'd seal it with a couple of coats of something decent like marine varnish and tape the joins with aluminium tape. If you can seal the edges too and a border round the underside before laying even better.

Whatever you use if it stays wet for a long time it will rot unless treated, so sealing is a good way to go.

If tiling on it check with adhesive manufacturer for compatiblity with your sealer of choice.

cheers, Pete.

yup

no no no

chip is fine where theres no chance of it getting wet. Water only needs to sit on it once and its a gonner, so quite uselses for bathroom floors.

The water resistant chipboard for bathrooms survives wet for ages, much to my surprise. Things like the carpet grippers had all rotted away, but the chipboard was still rock solid, in spite of being wet possibly for a year or more, and supporting an internal thermal block wall (also wet right through).

Standard chipboard flooring disintegrates as you suggests.

Ooh. This sounds like what I've been looking for for ages. Well, it would if it comes in a melamine finished version, but I dont suppose flooring does.

Sounds good, did it warp or expand much?

I suppose a good test for flooring chipboard is to boil a sample or give it a cycle in an old dishwasher.

cheers, Pete.

Not at all. I was worried about the wall built on it dropping, but it hadn't. I don't know if there are different qualities of waterproof chipboard. I think the whole upstairs floor of this house (about 15 years old) is built with it.

That sort of heat might have other effects. Just leave a piece outdoors and see what happens.

Seems to be a valid way of testing moisture resistance:

If using it for a project then a quick test would be helpful, though buying it from a reputable source should be a good start.

cheers, Pete.
