Bricking up window

[leedjc]

Morning!

I've just pulled out a window with the view to brick it up. I've got a couple of questions, I hope somebody can help me with.

Do I need wall ties between the two leaves? The window is 1m sq, so not very big

Secondly, I've discovered there's no insulation in the cavity. It's only a small wall...can I do anything about putting insulation in the wall now? Or is it best just to inject insulation later?

I tried uploading a photo or two...but it didn't work

The void that need filling is very small, about 80cm below the opening, 60cm on one side, and 30cm the other

You wont need cavity ties, but if you have two around, it wont hurt to put them in the middle

You can shove some quilt insualtion in the cavity if its clear enough. Rockwool bats might be easier to push in one piece. Otherwise the yellow drytherm stuff will go into clear cavities

Would it be worth pouring some of the ball type insulation down into the rest of the cavity?
