Description

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.

Questions & Answers

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
