"Biggest Screwfix purchase mistake to date. I should have scanned web for better value alternatives (and they are available). This arrived with separate pieces bonded to themselves. The product itself as well as being poorly bonded/manufactured was basically bog standard DPC badly glued to a strip of foam. The materials did not seem to reflect the cost of the product which explains why other manufacturers seem to produce similar product at a 1/3 of the cost. After a call to a polite lady at Screwfix I was given insulation manufacturers technical helpline number where a male operator rudely dealt with my enquiry in a passive aggressive manner suggesting that I was clearly wasting his time."
"100MM to me means it will close a 100mm cavity but this is not the case. The Extruded Polystyrene is only 40mm and the DPC 110mm. IM not a happy bunny - well with this part of the order I placed anyway."
"No indication given with this product about how it should be fitted. It has clips on one side and DPC on the other. I assume the DPC goes towards the outside. You generally need to trim the thermal closer since real brick work rarely looks like the perfectly formed drawings. This means you need to remove the clips and refit them. Not the best."
"Cost more than or equivalent to leading manufacturers brands but quality of this product is far inferior in comparison. A simple piece of foam with DPC glued to it. My advice would be to give it a miss. Overpriced tat in my opinion. Don't know what the performance or reliability would be. Chucked in the skip."
