Bricking up an external doorway

[SAULHUDSON]

Hi, i will be bricking up an external doorway hopefully this weekend, but just want to make sure im doing everything right. i plan on bricking up using thermalite blocks, am i right in thinking that i will need to tie these in at every other brick height with these frame ties to the existing bricks where the doorframe was - http://www.screwfix.com/prods/91531/Building/Builders-Metalwork/Safe-End-Frame-Tie-100mm-Pack-of-10
and at what level of the bricks should i use the DPC (If needed at all??) http://www.screwfix.com/prods/25271/Building/Damp-Proof/Damp-Proof-Course-100mm.
The external side will be rendered.

At the same level as the existing one!

Don't forget to use engineering bricks below DPC and your render should not go lower than the DPC -use a belcast bead.

The other stuff is correct

regarding the frame ties should these be drilled into existing brickwork before anything is laid and is it a case of one of the ends sitting on the block and then the mortar going on top of it. Sorry if this is a stupid question as you can probably tell this is my first time bricklaying. Thanks

No, its easier to lay the block and then mark and fix the tie.

put some expanded metal mesh across the joins before you render to help reduce or hopefully eliminate cracking.

Sorry to be a pain, but after i have driled the holes for the frame ties and put the wall plugs in, what is the best type of screw to use or will any do?

I also forgot to mention that it is a cavity wall so i presume i will need to use wall ties at every other level too to tie in with the 2nd wall (if this makes sense)

 

[r896neo]

Use stainless steel screws, and yes a few ties would be a good idea.

Is the rest of the cavity insulated? if so it is important to match that insulation in order to avoid a cold spot.

Just use any nr 10 screw at 1 and 1/2 or 2". Galvanised will do

You don't really need any ties across the cavity for this narrow opening - its being held at each end, and this is only an infill panel of no structural significance
