Show matter of insulation for the poultry house while dead or trapped air Is one on of the best insulating materials we have an air space between two walls does not insulate very well because the circulation of the air carries the hent heat or cold from one wall to the other says the wisconsin agriculturist but it if dry sawdust mill shavings or chopped hay or straw la is packed in lightly to fill this space and prevent air circulation such a wall makes a very warm and comfortable for table poultry house in using such filling however it la is wise to make the inner and outer walls as tight as ai possible so as to minimize the danger of the filling getting damp and partially losing insulating su value also the upper and lower boards should be put on with screws for quick removal so BO that the sawdust can he be easily taken out and gunnil d or renovated in ease caso it becomes damp or infested with mites |
