Kilt Posted October 27, 2021 Share Posted October 27, 2021 I’ve just had a new window put in, and was checking underneath for a draft. Ive found the concrete-precast sill has no DPC or much of anything behind it. There was a load of bricks just chucked in the gap, prior to photos. The external building is a rubble-stone barn conversion, all done in lime. what should I do, back fill the sill with lime mortar, to try and minimise water ingress? no way of getting a DPC in.

Ferdinand Posted October 27, 2021 Share Posted October 27, 2021 If it needs no more structure, I'd fill it with EPS, hopefully from a single offcut shaved to shape - possibly foamed in to fill the gaps. Or polybeads in a mixture with a bit of PVA, so they stick together and don't fly out again. The important thing is to vanish the cold bridge. Or you could make a secret compartment with a lifting lid. Link to comment Share on other sites More sharing options...
