Cavity Sleeve - Telescopic Air Brick

Ok, I am trying to fix a condensation problem.

Step 1 is to fit an air brick.

I now have a brick sized hole in my wall, double brick with cavity above the damp course.

I have just read that I need some kind of telescopic air brick/cavity sleeve. Where can I get one? Is this one:

Telescopic air brick is this.

It's used for venting under the floors and keeping the external air bricks well above ground level.

 

As per Stu above.

Pretty sure screwfix don't stock them - try your local Builder's Merchants.

 

I'm not venting under floor. Its at head height. The one I saw in my book goes straight through.

You're link includes the airbrick as well, which is fine.
You can get just the liners to fit an airbrick. I know Selco stock them. I think they're called cavity liners.
