I'm looking into the best most cost effective way of doing this instead of using the 150mm quilt insulation that the house kit manufacturer supplies in trying to get the u values down a bit.
On another thread it was suggested that i use Warmcel, but this thread has deteriorated to the point that i would rather leave it alone and start another. Warmcel would i feel be impractacle as the nearest installer with the gear to blow it into the wall frame lives too far away from my rural island location.
I have however been considering Kingspan Thermawall TW55 or Cooltherm K12 and would like to know if i could use say 50mm of this with 100mm of quilted insulation filling up the gap to the internal walls plasterboard. Is this a sound idea that would bring the walls u value down to around 0.2 or would i have to go thicker with the Kingspan? Or any other product for that matter.
Many thanks.
