Soon about to start casting our slab, and have some questions regarding different manufacturers' range of products for this.
We will use I-elements and wonder if anyone has any good or bad experiences with any particular brand?
At the same time, I wonder if there is any brand that is generally cheaper?
Finally, what different manufacturers are there? I have found the following:
Isover
Paroc
Thermisol
Legalett
Sundolitt
Siroc
Lastly, does anyone know a hardware store or supplier that has good prices on base elements and insulation for the slab?
