Is plywood available in Addis Ababa?

I was wondering if plywood is available in Addis? I am looking for 3/4 inch or 18mm thick plywood. If anyone can let me know where I can purchase plywood as well as lumber I will greatly appreciate at it.

Also I will be looking for good quality firebrick to make a pizza oven? I am not looking for regular clay brick (red bricks build bricks), I need high fire bricks.

Thanks
