TM Posted October 27, 2008 Report Share Posted October 27, 2008 Can i suggest you wrap your poly with plastic before you attach it to the walls etc. This will stop mosture getting into the poly, once this happens the poly is useless as insultion. Any holes you make need to be taped up to. No more nails or most glues for that matter won't be any good. Screws or nails with plastci washers worked best for me. Bunnings had them, used for holding weed mat down. Quote Link to comment Share on other sites More sharing options...

Umm sorry, I do not agree with the above statement. why then do they not wrap expol, or do they not wrap the poly that is layed into concrete for insulation. water has no effect on poly!!!! Fish bins are made of polystyrene, the get filled with water, yet the polys insulating characteristic does not change. why do you think it is used for disposible cups. Following extract taken from Expol website www.expol.co.nz Polystyrene Insulation has excellent thermal insulation properties essentially because it consists of mainly stabilised air. It is a durable, non-irritating, inert organic material which will not rot and is highly resistant to mildew No nutritive value to ants or rodents Suffers little or no effect from water or water vapour. Even under the most adverse and rare conditions of total prolonged saturation it maintains its shape, size, structure, cohesion and physical appearance. The effect on the insulation value is minimal Quote Link to comment Share on other sites More sharing options...
TM Posted October 27, 2008 Report Share Posted October 27, 2008 The Expol stuff is a much higer density than standard poly sheets. Expol is also best used along with thick plastic on the ground under houses to limit mosture rising. Concrete helps stop mosture getting in also. Sorry don't know what you mean by fish bins... disposible cups are just that disposible and can't be compared to walls of a fishroom or under floor insulation. I have seen and worked in a number of fishrooms that have not had this done and work fine for a while but given time they become water logged. IMO wrapping with plastic really makes a difference.

alanmin4304 Posted October 27, 2008 Report Share Posted October 27, 2008 You can buy a special adhesive for poly which has a solvent that does not dissolve it. Quote Link to comment Share on other sites More sharing options...

new zealand discus man Posted November 3, 2008 Report Share Posted November 3, 2008 Hi Std ploy is toxic when melts with fire..Had a big scare years ago when basement room got fire..Firebrigade said so toxic if were not up helping a friend with a sick dog we above would have all died...No question about it.. 100mm ploy is the same as roof batts..And batts are a lot cheaper.. You have been here before,come and go over info on room.. 124 tanks are heated in the worst of winter for $125 a month.. Also remember 5 tanks x 300watt heater is 1500w just like your electic jug..10 tanks is 3 kw and then maybe over loading power supply...Heat pump is by far the only way you can heat big area.......Phill Quote Link to comment Share on other sites More sharing options...
Simian Posted November 4, 2008 Report Share Posted November 4, 2008 Also be aware that polystyrene will suck the plasticiser out of TPS cables(the flat White stuff used in household wiring) all it takes is some movement, the insulation cracks, a little h2o and its all on :evil: I agree with Phill on this one, use batts and sleep well at night. You can get non migrating TPS which is safe to use around polystyrene, but would cost more. Quote Link to comment Share on other sites More sharing options...
Insect Direct Posted November 4, 2008 Report Share Posted November 4, 2008 so if using batts what would you then line/cover with? building paper and? Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted November 4, 2008 Report Share Posted November 4, 2008 Alloy foil with vapor barrier..Usually White like plastic then Tempered hard board...Will not rot..And also seals out drafts.. Under all that in my roof i have 4 layers of bubble wrap..Even over 4 huge sky lights. Rooms act like fire place..Air in say under door and out if there any small gaps in roof lining ..Just poly linning is just not good enough ,Still get big power bills... Mine is high gable roof so just about impossible to seal so around doors etc are sealed with closed body sponge seal.. Poster will remember the room here.. An other problem is power must be protected by RCD Unit on mains and protects all down lines..Stops sparkes up your bum...Phill Quote Link to comment Share on other sites More sharing options...
rockwork Posted November 4, 2008 Report Share Posted November 4, 2008 the best thing to use for your poly fixing is called GORILLA NAIL POWER that is wot i use for some of my poly you can also get diffrent density poly some light and some high and water has no affect to poly but make it float lol Quote Link to comment Share on other sites More sharing options...
ryanjury Posted November 4, 2008 Report Share Posted November 4, 2008 You can also get fireproof poly which is what I lined my fishroom with it was designed for us in household insulation.. I got a whole pallet load of 8ft by 4ft sheets for free.. Quote Link to comment Share on other sites More sharing options...

MrEd Posted November 6, 2008 Report Share Posted November 6, 2008 That stuff's pretty toxic Ryan! I leaned those sheets you gave me up against the house and it rained that night. Grass died and is still dead! Don't know what is used to retard fires but it'll retard your age limit! Quote Link to comment Share on other sites More sharing options...
ryanjury Posted November 6, 2008 Report Share Posted November 6, 2008 lol yeah you're probably right there I do handle it with care though use a dust mask when cutting etc (apparently you're supposed to do this with all poly?). I got it from a local insulation place I rung around asking for free poly.. They had stack loads of it and can't melt it down like they do to all the white poly because it was the fireproof stuff in it.. Quote Link to comment Share on other sites More sharing options...
