Hi,
I am looking to build a garden shed, using Breeze blocks. I have come across many different block types but have made the following 'conclusions' from my research. I am really quite confused by it all.....
- BREEZE BLOCK - no longer exists. Replaced by thermalite blocks.
- Thermalite - is this is an "AERATED BLOCk"? light, frost resistant, can be used for first course but NOT waterproof.
However, some say that they can be used for external leaf walls?
- CELCON blocks - are these the same as thermalite/aerated?
- Concrete blocks - heavy but WATERPROOF!
- What are aggregate blocks?
So what are "STANDARD AERATED CONCRETE BLOCKS" (as per Travis Perkins website?).
My intention is to lay with the thermalite blocks (lighter, better heat transfer resistance and cheaper), a single leaf wall from foundations up and then to paint with masonry paint. Will this be sufficient to waterproof?
I am really confused as some external aerated blocks are described as being waterproof to building regs (Celcon Block Standard Grade 3.6N 440 x 215 x 100mm - JESWONS), so in my mind means they do not even need painting/sealing. For clarity, I will paint for aesthetic appeal even if not required for waterproofing.
I have read several conflicting bits of info and my lack of understanding after hours of research is actually driving me insane.
Any help much appreciated!
Thanks guys.
