Advice on bricks for an extension

theGrinch

I need to source some London yellow stock bricks.

I have found some without the frog.

The wall is 4m (width) by 3m (height) with block and cavity on the inside.

Is there any structural difference between having the frog or not?

Thanks

Frog or no frog does not matter.

No frog is quicker to lay and requires less mortar.

It could be argued the frog helps with bonding the mortar but for houses this would not matter.

You just need to be sure your chosen brick meets your requirements for frost resistance and for salts

Many thanks. It was pretty much in line with what I expected, which is good.

I will be using reclaimed sourced locally from an external wall removal that was 100 years old.
