    Cheapest place for 75mm + 12.5mm insulated board these days?

    My supplier I used last time for seconds wants £48 for 50mm boards. Prices seem to have gone up loads since my last year.
    Any recommendations? They're coming in at £72 a sheet...

    Insulated plasterboard can either be insulated with EPS or XPS and I've found the price varies.
    Ringing around I've got as follows:

    Minster Insulation: 78mm Thermaline £44.41 + VAT. Minimum order 11 sheets. £20 delivery
    Encon: Celotex PL4000 72.5mm £43.96 + VAT. £25 delivery
    Robert Price: 83mm Ecotherm £55.00 + VAT. £10 delivery
    Thrmaline Plus (XPS) or Super (phenolic)?
    I did specify PIR, so I guess the latter...?
    We've decided to use 3" boards, baton and board instead as we have some available.

    But I do intend to use composite boards in my attic, so is there a preference you'd go for?

    PIR is not phenolic
