Question:
do i need to install a vapour barrier if installing under a timber flat roof deck
Answer:
The Celotex XR4150 General Purpose PIR Insulation Board is designed with a high water vapour resistance, which means it can help limit the amount of moisture that passes through it. However, it is often recommended to use a separate vapour control layer in conjunction with insulation, especially in areas where high levels of internal humidity are expected, like kitchens or bathrooms. The ultimate decision would depend on the specifics of your project and the overall design of your roof. It might be best to consult with a building professional or your local building regulations to ensure you have the most appropriate solution for your particular situation. It's also beneficial to refer to the BBA Certificate and Data Sheet for more detailed technical information.
