    Key Points

    • • Pink board in garages is building regs — 30-minute fire resistance
    • • Green board behind tiles in bathrooms — standard board will fail over time
    • • Colour coding is industry-standard across manufacturers
    • • Thermal laminate boards count towards your U-value calculation
    • • Foil-backed (duplex) acts as vapour barrier — face foil towards the warm side
    • • Impact-resistant boards take direct screw fixings for heavy items
    • • For fire-rated assemblies, use the exact specification in the fire test certificate
