Porotherm Clay Blocks

[Estimator#1]

Has anyone in UK used this product recently?

I haven't in the UK but I used them a lot in Germany in the 90's. What's up ?

I looked into them 5 years ago and couldn’t find anything to put in the plus column, so the got dismissed.

To me these are Mediterranean products appropriate to the climate . The insulation provided is very low. Their main advantage is in allowing rough work to be resolved by the following trades; easy to hack into shape. Perhaps some brownie points for not  being made with cement.

Our local Lidl got its main wall built with these, went up quick.

It wasn’t very Mediterranean in Germany. Hot summers and very cold winters the blocks performed well. I see that now you can buy an insulated version that must improve the u values no end.

Dampness is the UK differentiating  issue. Yes you could use them, but I don't see an advantage that justifies the cost.

The company has a factory in Kent, but don't appear to make these there....for a reason.

As I was saying.   Appropriate in a different clime. This is much better work than the typical  but will be covered in several coats of render. Fixing door jambs and conduits is a different technique. I appreciate that these are fairly basic blocks.
