Questions & Answers


What depth of filling is required to meet modern standards ?


The minimum filling depth you'd require is 100mm to also achieve 3m2 per bag. 


How does this product work in areas that may become condensated? Is it moisture wicking?


ThermoFloc is breathable but it is not recommended to use in an area of high condensation. 


What is the actual size of the bag, I need to know to make sure I can get it i to my loft space. Thanks Graham Harrison


The bag size is 12kg


Can it be blown into a space with restricted access?


This can be blown in, but it would have to be done by a registered professional, as this isn't a service that we can provide.


What is the approx volume that each bag would provide when laid under a floor?


For this product in particular, you would get 3m2 coverage per bag, and that is based on 100mm depth
