Cavity wall insulation- Thermal bridging psi values

[Jordan1]

Hi All 

 

Does anyone have any alternatives to kingspan that can provide psi values for a 100mm brick-100mm cavity (with 50mm insulation board) and 100 mm dense concrete block?

 

I was first looking at QUINN/MANNOK as its about half the price, have all the relevant details except for psi values when using a 50mm insulation board. Essentially what I'm looking for is similar to the attached with a cheaper product so wondered if anyone had had any luck with this

 

Thanks

Kooltherm is Phenolic, I don't know of any other manufacturers that do this type insulation, others are PIR. Take a look on seconds and co, you may get some cheaper on here with a few knocks to it, or a few mm out.

Boards in the cavity isn't the best choice. Plenty if threads here if you search.

 

Eps beads or full fill mineral wool are a more robust option along with standard 7N blocks. You'll need a wider cavity for the same U value however.
