If you are able to get a couple of planks up there, three quarters plywood or 2 by 8 or 2 by 10 planks so you can get your weight well distributed across five or six of the 2 by 4 stringers should work fine. You won't come through the ceiling so long as you stay on the planks and by distributing your weight over several of the joists, say 6 at a time a 200 pound man is only applying about 34 lb. per joist. There are probably additional slopers if this is a truss based roof which are also relieving some of the load.
If there is already insulation filling the bays I suggest you run the additional insulation bats across the joists to further fill over any gaps and further limit thermal bridging through the joists. Don't forget to leave ventilation space at the eves so air can flow up over the underside of the roof decking Dale Leavens, Cochrane Ontario Canada [EMAIL PROTECTED] Skype DaleLeavens Come and meet Aurora, Nakita and Nanook at our polar bear habitat. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <blindhandyman@yahoogroups.com> Sent: Sunday, August 06, 2006 9:45 PM Subject: Re: [BlindHandyMan] home remodeling ideas > I'm in the same situation as I find that the insolation in my attic must > be under done. > I thought of 2x 8 ft halves of ply but crossing that 20x 14 ft above the > livingroom was nearly doomed to crack plaster while I lay out bats of > insolation. > How do we cover this? for material and personal safety? > > > On Sun, 6 Aug 2006, Shawn Keen wrote: > >> Okay, I had another look. >> >>> What do they have for a floor up there now? >> a board that's probably about 3 foot wide and 8 feet long. that's a >> guestament. >> the beams up there are 2 by 8. >> Only the space just beyond the ladder and too the air conditioning unit >> is >> covered right now. >>> >>> Generally you wouldn't be able to get sheets of plywood up through the >>> trap >>> door so you will need to use plank construction.
