Marmox Thermoblock or Foamglas Perinsul

[BenP]

Any thoughts or preferences on the above. 

 

I recognize the difference between the two - Foamglas Perinsul is stronger (throughout) but less thermal performance. Thermoblock performs better but achieves compressive strength via inserts within it. 

 

It strikes me that the Foamglas has the benefit of acting just like a block so should be easier for the groundwork to adapt to? Most builders don't seem to be aware of the type of products or detail it's associated with!!

Perinsul marginally cheaper from searches - 1.5k vs 1.6k.

How much of a difference do these make compared to a dry airated brickette?

About 80% less heat conduction relative to dry autoclaved aerated concrete

I wasn't aware of the exact figures so ta!

 

We're having a suspended beam and block floor due to ground conditions so it's the one weak point in the thermal envelope - especially as the roof and walls will be timber frame insulated between and over.

Have you also looked at armtherm?

Thanks - fewer bits of information and suppliers online but I'll get in touch.

Thanks - looks positive. 

I'm going to get the engineer confirm what compressive strength he's after beneath the sole plate. ? - might inform the decision!

Can I ask what you went with in the end and if you have any advice you can share from experience gained?  Asking myself the same question right now.  Cheers
