I have read several articles, most recently an sustainable energy guide, that loft insulation should be laid in between the joists and then another layer across them (this is the case in my loft) and this should not be compressed if laying flooring for storage purposes.
If this is the case, how would it be possible to actually lay flooring without compressing the insulation? It also says that battens may need to be fixed to the joists in the proposed flooring area to raise the flooring in order not to compress the insulation. Again, how could this be done without breaking the second layer of insulation? This would also add to the load and risl cracking the ceiling beneath.
I considered boarding the loft on top of the existing fibreglass insulation, then putting a layer of rigid insulation on top and finishing with boarding on top to create a sandwich.
I have since discounted this as apparently moisture would get trapped in the fibreglass insualtion which would render it ineffective.
I've heard of Softboard which apparently is breathable and a more effective insulator than other rigid types.
Any advice/tips would be appreciated.
