We are planning a new build in southern Tas and thinking of incorporating phase change for thermal mass - possibly ceilings and some upper walls. Has anyone had any experience with this product, or similar?
What happens if the containing membrane is broken (eg accidentally pierced with nail, eaten by rodents, manufacturing fault)- does the solution leak through to the ceiling or cause other problems?
I assume if it is in the walls or ceiling it is placed directly behind the wall/ceiling surface?
Should it be placed near a wood heater? What about a bedroom that faces east and another that faces north - is it worth putting in here as well?
The house will be well wrapped with sealed membrane and insulation, double glazing with most windows facing north, on an insulated slab, plus a couple of stone features in side - stone fire surround and stone wall in sunroom.

Roz,
I think Knauf has just released (in Australia) a plaster board product incorporating PCMs. It's called "Comfort board" and the details can be found here-

I don't know anything about it though. Perhaps someone here has used it?

I have just contacted an agent in Hobart, Brock Plaster who very recently added Knauf comfortboard to his list of products. Will be visiting his business tomorrow. Have been told it's around $120 per square meter! It had want to be good.......

Given that it is a new build, would it be cheaper to use real mass instead? For example, a brick internal wall?
I'm thinking about retrofitting some PCM, but wish I'd pushed for an internal wall to be made of brick instead.

better beed up the frame and use several layers of plasterboard, more rigid that way. Is there 13mm plasterboard in the usual hard sponge quality?
