The SuperFOIL SFTV serves as a comprehensive building membrane for the construction of roofs, walls, and floors. It offers both water and vapour resistance and also acts as a foil radiant barrier to minimise solar heat gain during summer and maximise insulation in winter.
Additionally, the reflective properties of SFTV boost the overall uValue of the building structure. For optimum energy efficiency and performance in both new constructions and retrofit projects, SFTV is an excellent choice as it functions as an 'airtight' layer, suited to the entire building envelope.
Moreover, SFTV's waterproof and vapour-proof features, along with its radiant barrier function, help prevent the growth of mould and dampness. It also enhances the thermal resistance of the building structure, ensuring maximum energy performance.
With two air gaps, this product offers a thermal insulation R-value of 0.95 R for roofs, 1.42 R for walls and 2.8 R for floors.
Question:
Could this product be used for under carpet insulation,
Answer:
It can be used under carpets but is a vapour barrier so will not provide much in the form of thermal benefit, I would reccomend the following as a better alternative - https://www.insulationsuperstore.co.uk/product/superfoil-sfuf-underfloor-foil-insulation-15m-x-8m-roll-12m2.html

Would this be suitable as a vapour barrier when building a sauna room?
