Hi - I need to build a single block wall on top of an existing cavity wall for a first floor extension but can't find anything to 'seal' the cavity with prior to building .. can someone point me in the right direction?? Thanks!

bashypack,
Not sure what you mean by sealing but google 'cavity closers' and see if this meets your requirements.

..Thanks - yes that is more what I meant something to close (rather than seal) the cavity so I can build a single block wall on top of a cavity wall - I wasn't sure what they were actually called so I am sure that will help!
