Are all the bonded beads the same ? I am getting quote and they are talking about 'graphite' and 'platinum' bonded beads and they are all 'certified' and they are all around the same price. So are they the same products really ? They did talk about U-Values but they sounded same too.
How do I know I am getting best bead for my buck ?
I had read somewhere that the foam should outlive the house! (I can't find the link). The premier website says that "Unlike Polystyrene Bead, Foamfill is Fire retardant, Rot Proof and will not sustain Fungi or Mould Growth."There are many previous threads on this subject I think. I believe the foam is not long lasting and the beads are a much better option... long term anyway.
A friend of mine had the foam installed a number of years ago and it just turned to dust on contact when he was recently doing some work on the house.
You may need to be persistent, see here.
This thread hasnt discussed the use of blow-in mineral wool insulation at all..
Syd, is mineral wool, when placed in a wall cavity, not prone to moisture absorption which leads to sagging, poor insulation performance, etc.?
