andreas Posted September 1 Share Posted September 1 I am going to block an external doorway up. The lintel will remain above the doorway. The existing internal leaf is cinder block. Is there any disadvantage to using thermalite blocks to block the hole up? I have enough of them to do the job sat waiting to go in the skip and would have to go and buy anything else if they are unsuitable. Link to comment Share on other sites More sharing options...

Would that be an issue? Link to comment Share on other sites More sharing options...
