The everyday kitchen tablecloth was always flannel-backed oilcloth. For some reason, large cabbage roses were often the decoration of choice.Rubberized sheeting was used to make waterproof sheets for a crib (soft fabric bonded to rubber). I made sheets, lap pads, etc when my daughter couldn't wear disposable diapers OR rubber pants due to severe diaper rash.These items were always bought at the five dime (Woolworth's, Belmont's, Ben Franklin's, or what-have-you). Now that those stores have gone the way of the dodo bird, are these products still available?
Vasaline works, just apply a thin thin thin coating to your mold.
There are also dual technology types which utilise both (PIR) infra-red detectors and microwave for fool proof detection without false alarms. To protect windows you will need double or triple knock vibration detectors which can be wired or work on RF (wireless). Motion detectors (PIR) operate on the principle of temperature changes across the sensor; a person walking across the room indicates suddenly (moving) temperature change. An open window will trigger also as this is a sudden change in temperature. Sensors do not respond to very slow movement or very quick movement (fly) across the field. CH temperature change is very gradual and stationary thus the heat source does not move across the fiels as a body would.
