Hi all
I recently moved into an old house (approx 250 years old) and have found the old insulation to be fairly thin and broken down (about 1cm mostly thickness mostly).
Since I have 4 inch joist height, my plan is as follows:
1) remove all old dust/rubbish/insulation (bag it all up) 2) staple down polythene sheet strips between the joists (to prevent moisture entering the loft) 3) lay down 4 inches (100mm) of rockwool insulationOnce that has been achieved, I was planning on putting down 6x2's across the existing beams to give me a total of 10 inch of effective joist height.
so phase II was:
1) put down 6x2's across existing joists 2) lay 150mm (6 inch) rockwool inbetween the newly defined joist space 3) board out loft for easy access/storage in the futurehowever I then stumbled across Polyfoam Supadeck on the knauf insulation site.
Now to my questions.
1) does any of the above make sense? 2) does phase I seem sane? 3) does phase II seem sane (either one). 4) am I sane!?Also, I am having the house fully rewired in a few months, and wondered what the best advice would be on where and how to run the cables in the loft.
Sorry to have wittered on, but I hope someone can help me with my first major diy project.
Thanks
Dean.
