new build here

a friend suggested to use 35mm insulated slabs as opposed to the standard 1/2 inch ones for the ceilings in my new build bungalow

not sure if they are worth it from a cost point of view, and I have only the std ceiling height of 8"6" and every inch counts!!!

has anyone used these? are there any do's and dont's while installing them.
Are they a success??

Cheers

sacrifice the inch for a lower heating bill.well worth it in the long run.use 2 inch slab screws
 
If height is an issue, then dont sacrifice the 1" internally... just put extra insulation in the attic.

the min current regs are approx 300mm quilted material or 200mm foam board... upgrade these by the extra 25mm..
 

looking at it logically if you use the slab boards you will save on the cost of the sand & cement layer so you'd only need the slab board followed by a skim, so the cost would only slightly be extra but the long term heat savings would be huge

The air tightness experts would recommend that the walls be sand and cemented before applying the insulated slabs
 
i was talking about ceiling slabs
but you are correct and i am planning to insulate innner leaf with insulated slabs also

sorry, but how could you miss 25mm at ceiling height ?? The doors are only 2100mm high, which is 490mm lower............what's going in the room that won't come through the door ?

As an aside, def do, for insulation purposes, big ++
