Glasroc F FLAMELINE

What is it - Its a new one to me

New one on me as well..

have looked at the website but it does not explain in detail where it can and cannot be used1 Plumber has fixed it but I have never heard of it until today!!!!

It has fibres through it to give strength, it's strong but can snap quite easily.

I be calling British Gypsum technical to confirm it's use.

08705 456123 and ask for technical

Why has the plumber put it down? Did he give a reason?

no idea why he layed it, told the customer he had used it before and is better than plywood!

Very strange!
As it happen's i'm using this tomorrow to seal around a gas stove around the flu,then sealing it with fire stop. As Whitebeam says it's basically a fireboard!
Think i'd be ripping it up and putting a proper base down. Sounds like the only explanation is something to do with a firestop to the floor underneath. Which theoretically should be double boarded with fireboard (plasterboard)oops out of room.

There has been mention in the past of someone using plsterboard on the floor instead of ply or a backer board. Perhaps this plumber decide this would be better??

I remember that about plasterboard on floors

I can't see any reason why this would have been used??? Used mainly in commercial buildings or tower blocks to protect the integrity of the structure from fire.

I can't think i've ever seen this used on a floor and certainly not as a tile backer

Nice speech Colour Republic.
Just to clarify when I mentioned p/board it was for the ceiling underneath.
Also do you think this glasroc is not No More Ply (just a thought)?

Bathroom floor you say?
