Sorry, another joist related question from me...............
When I build a joist into a new wall, how do I actually do it?
My plan is for the joists to sit directly on top of a course of blocks, and then the other end will be on a joist hanger attached to a ledger board.
I will take the level from the top of the blocks.
I had assumed that I would cut a block so that the vertical edge was in the right place for the side of the joist.
Position the joist next to the block, and then place the next block.
Joists will be on 450mm Centres, so each block will need to be cut down accordingly.
Do I bed the joist in Mortar on all 4 sides? ……………….. and then seal with Silicone afterwards.
If I opt for a joist shallower than 220, do I notch the blocks so that they encapsulate the joist, or do I cut them off vertically, and just fill the void with Mortar?
Originally, I was going to fit 220 Joists so that I could get loads of insulation between them, but on thinking about it I think I would probably be better off fitting shallower joists and then fixing Celotex directly to the underside.
