Nuspan precast insulated floor system

[RookieInBristol]

Hi everyone,

Just embarking on a self build project on the outskirts of Bristol.

I’ve been looking into Nuspan as a cost and time efficient alternative to an insulated raft + floor build up.

We’d lay ufh and a screed on top.

They quoted ~£100/m2 plus £4k for complete installation onto pre-built strip foundations.

This seems a no brainer? Am I missing something?

I’d appreciate perspectives from anyone who chose Nuspan or a similar system, or has some knowledge in this area.

 

Thanks!

Sorry, I don't know anything about Nuspan but are you sure it's a cost saving alternative to insulated raft if you have to install strip foundations beforehand?

Or is this a suspended prefab floor system?

Have you worked out the cost for strip foundation + Nuspan versus insulated raft for your total floor area?

In that case I suggest more homework.

 

I see that this system has the insulation bonded under it. What thickness insulation for £100?

Is it structurally complete or does it need more concrete on top.

How far does it span as quoted?

 

It is certainly a quick and clean way of suddenly having a floor. Do they include craning and is solid access avaliable?

 

Is there a reason for a suspended floor?

They are 375mm deep and claim a U Vale of 0.14, down to 0.11.
