Blake Posted January 21, 2005 Share Posted January 21, 2005 I'm lookign to buy a sheet of tyvek (4'x8') to use as a floor for my beta-light. Anyone have a dealer? If this isn't really doable, anyone have experience with Integral Designs Siltarp 7oz $60? Quote Link to comment Share on other sites More sharing options...

marylou Posted January 21, 2005 Share Posted January 21, 2005 (edited) Housewrap is sold by the roll, and besides, it's a bit on the heavy side. I got Kite Tyvek from this place for the floor of my Beta Light. 4 x 8' piece ran me 10 or 15 bucks and weighs 6.2 ounces.

Blake Posted January 21, 2005 Author Share Posted January 21, 2005 Do you REALLY want something that's vapor permeable for your tent floor? http://www.tyvek.com/whatistyvek.htm  Not if that means i'm gonna be wet when I sleep on snow and wet ground. Allison, how's your tyvek floor holding up on the snow? Quote Link to comment Share on other sites More sharing options...
marylou Posted January 22, 2005 Share Posted January 22, 2005 It hasn't been in the snow yet, sorry. Quote Link to comment Share on other sites More sharing options...

I have had good luck with them on the snow. I did have one time last year that I got a little damp but then again it was in the upper 30's low 40's and every thing wa slowly melting. Over all I have been pretty happy with mine. I may have a piece you can have Blake how big you looking for? Quote Link to comment Share on other sites More sharing options...
Squid Posted January 22, 2005 Share Posted January 22, 2005 The Integral Designs SilTarp is pretty cool as a wind/rain break, but it wouldn't hold up if you used it as a groundcloth. Quote Link to comment Share on other sites More sharing options...
max Posted January 22, 2005 Share Posted January 22, 2005 Just what is the thought behind something breathable as a ground cloth? Seems like heavy weight visqueen is lighter, cheaper, and easier... Quote Link to comment Share on other sites More sharing options...

I may have a piece you can have Blake how big you looking for?  Roughly 8'x4'  I guess I just want the lightest stuff that is fairy cheap, tough, and waterproof. I had presumed that this was tyvek, but maybe i'm wrong. Quote Link to comment Share on other sites More sharing options...
crazyjizzy Posted January 22, 2005 Share Posted January 22, 2005 I have a big roll of tyvek. PM me with your address, and I could mail you a 5'x9' piece. Mail will cost one of us probably $1.00. Quote Link to comment Share on other sites More sharing options...
genepires Posted January 23, 2005 Share Posted January 23, 2005 Trash compactor bags are cheap, available, and waterproof. Cut a couple into sheets and tape them together insuch a way to fit the floor of your tent. One bag can cover about 75% of a one person tent.

crazyjizzy Posted January 26, 2005 Share Posted January 26, 2005 You greedy son of a bitch, yesterday I mailed (on my own dime) the young man a piece of tyvek 9' x 12' for free.

tshimko Posted January 26, 2005 Share Posted January 26, 2005 While Tyvek is rated as moisture vapor permeable, do you really thing that something like polyethylene sheet is vapor impermeable? Â Think again. Â Almost any plastic film will transmit moisture vapor (or in fact any other vapor). The differences are how fast. I don't have figures, but I'll bet you probably not notice the difference overnight with either as a ground sheet. Quote Link to comment Share on other sites More sharing options...
marylou Posted January 27, 2005 Share Posted January 27, 2005 Tyvek get a nice soft fabriclike "hand" to it after being run thru the washer too. Quote Link to comment Share on other sites More sharing options...
Braumeister Posted February 6, 2005 Share Posted February 6, 2005 Assuming the Tyvek benefactors on this board exhaust their supply, you can stop by any construction site with a six pack and get what you need.

Thinker Posted February 8, 2005 Share Posted February 8, 2005 (edited) Tyvek has a spec'd hydrostatic head (the pressure required to drive water through the fabric, in this case) of 56 to 83 inches of water, which equates to 2 to 3 psi...not very much, but certainly enough to keep out most wind driven rain. web page1 web page2 web page3  But, not enough to keep water from seeping through under body weight. I'm not about to calculate the size of your ass and divide it into your weight to see what psi it might exert, but suffice it to say you'd probably get wet sitting on most Tyvek on wet ground.  I recalled from working in Tyvek suits that I'd often get a wet knee when kneeling on wet ground so just now I set a wet sponge on the floor, placed a layer of Tyvek coveralls on it, and kneeled on it for 10 seconds....voila...wet jeans.  If you're set on the durability and light weight of Tyvek, I'd suggest finding some that is coated with polyethylene or saran (not to be confused with sarin). Google Saranex for some ideas.  In any case, try the wet sponge-tyvek-knee routine on what you get/got and let us know.  And for a little CBS-style trivia, Tyvek isn't very good at preventing drugs from passing through it... web page  (yours truly in my favorite shade of Tyvek) Edited February 8, 2005 by Thinker Quote Link to comment Share on other sites More sharing options...
