Cavity wall insulation- Thermal bridging psi values


Recommended Posts

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

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.
