Hello all,
Currently part of my loft floor is boarded with only 10cm of insulation underneath. The rafters are 7.5cm deep so insulation in this area is compressed.
I have enough off cuts of fence posts and enough gravel kick boards in garage to cut up and create a structure to support the existing boards and allow for 17cm of insulation plus 5cm air gap. I plan to sandwich post offcuts (positioned to meet the existing roof structure) in between the gravel boards and fix the existing boards in top.
So more in the style of loft zone type solution.
Was going to run the new structure at 90 degrees to the existing.
My questions are:
Given the existing structure is only 75cm deep do I need to retrofit noggins? If so what's the easiest / quickest way to accomplish this?
Should I be concerned about creating a cold bridge (excuse me if this is not quite the correct term) and if so how should I prevent this?
