Self build, considering sandwich panels

Superdaddy

I am about to start my self build. I am aiming for an A rated house. I haven't decided on a method of build yet. I am considering using a precast sandwich panel wall with insulation in the middle.
The precast company making them is based in Meath.
This is their product info.

** Walls are made using the “Thermomass” or similar “Megablock” or alternative composite wall panel system under the German D.I.N. Zulasung Certification Process. These wall panels are manufactured as “True Twin Walls” – i.e. both faces are cast on a fine polished steel pan and oscillated to achieve a exemplary finish. This differs to our competitors who use power-floats which provide an inconsistent finish.
Both leaves are tied together using pultruded glass reinforced fibre rods. The wall panel is then filled with in-situ concrete on-site to provide a robust monolithic concrete structure.
Advantages include:

• Time saving – fast track construction method
• Reduced labour on site – less operatives required for erection process
• Insulated – wall panels with U Values ranging from 0.15 – 0.30
• Reduced drying out time required – walls can be decorated immediately
• Excellent Acoustic Qualifies – typically 50 DB reduction for a 200 mm Twin Wall.
• “Paint Ready” Precast Concrete Twin walls are cured in factory conditions

Does anybody have any experience of this build method or this product?
I am waiting on a price. It seems a very good way to build and if it is cost effective it could be very quick. No need for plastering, conduit and electrical boxes already fitted and airtight. It's a bit like reversed ICF.

Any day now I hope. Its a week over due.
It's more of an industrial building technique. But I think it could be very handy for self builds. My plan at the moment is to build in a modular style, getting companies to do various parts of the build. I want to cut out waste of materials and time, I really don't want to be chasing block layers and plasters.

Had a look at them. How will they be strong enough to take a roof in a normal residential house? Look like more suitable to factories or warehouse where there is a steel structure in place already.

My understanding from talking to the rep is that they can vary the amount of concrete and insulation the customer requires. I hadn't thought of the walls not being strong enough to take the weight of the roof. I will discuss it with my engineer and the precast company. Thanks.
