thin joint mortar availability

[Caversham Passivhaus]

Does anyone know a supplier of thin joint mortar for use with aircrete blocks (thin joint system)?

So far I have determined:

 

• Thomas Armstrong, Airtec Aerated Concrete Blocks are best for thermal conductivity but don't have a supply of the thin joint mortar.
• Celcon can provide the mortar if you use their blocks.
• There is the product in Poland, and I am investigating this option.

 

I only need one 25kg bag for now. Does anyone have any stock?

Don’t bother. 

I read your other post, for such a small amount of blockwork your heat loss from a regular joint to a thin joint is so small it’s not worth even entertaining the idea.
