Warmcel for pitched roof

[Jaygti]

I was just wondering if this Stuff is worth looking at, to insulate our new pitched roof. 

 

I was was originally looking at Celotex, and still might go with it, especially as i can fit it my self. 

The problem is it seems to be poor as a sound insulator. We have a shed with 65mm of Celotex in the roof and it’s very noisy when it rains. 

 

Also I guess I will still need a layer of Celotex on top of the rafters to stop any thermal bridging. 

Finally what sort of rough cost would it come in at for an 80sqm roof?

thanks in advance

Our roof has 400mm of Warmcel pumped into it.  It works very well, and has a reasonably long decrement delay, which helps to stabilise the temperature a fair bit.  It's very good as acoustic insulation, too.  Our bedrooms are room-in-roof and we can't hear when it's raining outside at all.

 

I'm not sure of the cost, as a lot would depend on how easy or difficult it is to install in your specific roof.

Thanks, I shall definitely investigate further then??
