Closing cavity end.

Mar 22, 2008 9 Replies

Hi, My conservatory project is finally making progress. Underfloor heating is down (presurised, but not connected, until the screed is fully dried). Windowsill boards are on.



I'm not sure how to neatly close off the end of the cavity (as you can see I am using unfinished brick).

suggestions?


Just mortar in pieces of brick, cut to size, into the gap; ideally with a vertical strip of DPC within the cavity against the external leaf of the wall (so you'd *just* see the edge of the DPC protruding much as you can along the base of the wall).

insulation fits in the cavity and one outer strip is nail into the brick joint and the other is trapped behind the frame of the jambof the door or window

Do you know who sells them online, or what they are called? Would like to look at one, as it sounds just the ticket.

Thanks,.

================================= This is one version (cavity closer):

Cavity closers. All builders merchant sell them but don't know if they sell in packs or singles. I see from the other mail that Screw fix sell them, with postal charges could be expensive.

Just wondering what they do, that a couple of squirts of expanding foam in there doesn't do. I was more asking about how to finish it off aesthetically, rather than from a thermal/damp point of view.

Can't really tell from your pic, but is there edge insulation on the screed?

Yes there is, it's been trimmed down flush ready for tiling.

My original solution was based on the requirement for aesthetics, as you'd said you were leaving the brickwork exposed - you wouldn't use a cavity closer unless you were plastering over.
