Hi, I am going to lay some more loft insulation over the top of existing Vermiculite. The Vermiculite is about 2in and the rafters are 4in. I intend to lay some 2in timber directly on top of each rafter to create a 4in gap, lay 4in loft insulation in this (to make a total of 6 in) and then board the loft over it all.
My question is that the space between the rafters is 35 cm and all of the loft insulation for sale seems to be either 40cm or 60cm.
Can i squeeze 40cm loft insulation in this gap? Something tells me this is not a good idea as it needs to 'breathe' or is it possible to cut it how you like? I was planning to use the 'sealed in a bag' stuff but assume this is out of the question as it needs to be cut.
Any advice/opinion gratefully received.
