Tiling up to an external door - how close?

[matthew4444]

Dear All

I'm in the process of tiling the floor in our new extension using porcelain tiles. The new hallway has a screed floor and where the floor meets the external wall and doorframe there is about an inch/ inch and a half of kingspan foam insulation.

My question is how far should I tile up to - to the edge of the kingpspan or just over? Obviously the adhesive wouldn't stick to the foam and both would leave a gap with kingspan showing - I'm hoping to cover this with a PVCu edging strip to match the door frame. Has anyone else had this problem and has anyone got any solutions?

I hope this all makes sense. Any advice gratefully received.

Regards

Matthew

A PVC edging strip should be fine, although (whilst it'd be a bit of a pain) laying a piece of wood on top of the insulation, then tiling on top of that would probably be your best bet. Hope this helps.

Yes, many thanks.
