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
