Hi,
I understand I need to backfill my cast iron insert fire with vamiculite. That I cannot simply slide the insert into the builders opening and leave a large void behind it.
Can I reuse the old red bricks to form this smaller opening? They will be behind the insert and not on show. Or do I need specific fire bricks for this?
Thanks,
