Ctd contract insulation boards

[Sean SML Tiling]

Anybody know if these boards are water resistant or water proof?

Do they have a make connected to them...

Used them last week to overboard a wooden floor before tiling.
Not sure if they are waterproof though.

They are very similar to Wedi boards except the foam is pink/red,
Easier to cut as well they don't seem as dense on the concrete face (if you know what I mean)

 

[White Room]

From my understanding it's the foam that makes them waterproof....

Waterproof on the surface. Using them over three bathroom floors and for bath panels.
Youll still need to tape up joints though if youre using it in replacement of tanking.

They are jackoboard from recollection?

 

[White Room]

Price is good though...

I was going to switch to these from Hardie backer boards but I think that Hardie feels more secure when overboarding timber floors.
