Schluter Ditra used only for part of the job?

[1justin]

I'm considering buying some Ditra to bridge areas where old conc floor meets new extension. There is no UFH. I was considering a strip perhaps half metre (or maybe full roll width) wide over the areas (mostly doorways), along with expansion joint.
Is this a common way to do it, - being economical with the material?

The new extension part of the screed has some cracks where it shrank a little. It's now fully cured (6 months) and appears stable. Would I be advised to use Ditra in these crack areas of the screed also? The reinforced slab underneath the screed is very solid. I'd sooner not cover the whole area since I have 50M^2.

Tiles will be are 600x400 travertine on a thick bed.

I would definitely recommend laying Ditra over the entire area with trav. If the price is the issue then it may be worth shopping around for other decoupling membranes, Dural do a very similar product, click on the sponsor link on the lest hand side and have a look. Be aware that you may need to include more expansion joints in the floor if it is 50m2 (min of every 10m).

Thanks Rich, I'll look hard at that as an option. I've been reading up on the Durabase Ci as an alternative. Learnt a lot in the last 24 hours..
