A PVC-caoate polyster fabric matrial yarn has tear strength of 80/65daN, that is mentioned by the supplierWhats meaning of tear strength's this unit of daNIt is obvious that daN means dekanewton, but whats meaning of giving 80/65daN.? if anyone can mention it with proper detailThanks
You can cover it up or even stop it from turning, as that is what I did with mine because when it turns, it squeaks really loudlyBut I just recently had the electric company come out and insulate my attic and I was told that their should be 2 fans up there so that the air could circulate and then exit, instead of the hot or cold air staying in there and coming into my kids room thru the attic door in their ceilingIf you are low income, check to see about free insulation from your gas or electric company and they will put in another fan for free as well, if you don't have one.
No don't cover it upMany times, people make the mistake of trying to seal the attic in the winter by putting plastic bags over whilybirds, ectBut the fact is that attics are designed to always have air circulation to prevent mold and mildew from moisture accumulation.
Yes! Having the ceiling fan going while the air conditioner is running will help circulate the cool air and which will cool the room off quicker and could possible not over work the unit as well.
If you are referring to a whole house fan usually located in a hallway the answer is yesThe best thing would be to build a box of plywood that will fit over the entire unit from the attic This can then be covered with sheet foam to make it insulatedThe reason for the box is that you don't want to lay anything directly over the fanIf someone accidentally turns it on, it would probably be damaged and need to be replace You should be able to do an average sized fan cover for around $60-75You're losing much more in heat over the heating season, so it would be well worth it, not to mention the added comfort level.
Tear strength is usually the maximum load divided by the thickness of the materialIt is possible that the 65 represents the thickness of the yarn in some wayGood Luck
