The most effective and also the best method to decrease the energy consumption and also the cost of heating curtain sided sheds is to use poultry farm insulation. Side walls of the poultry farm are very poor for temperature and moisture insulation and pass more than 25% of heat through it during the winter season. Another disadvantage of sidewalls of the poultry house is that they are the good source of air seepage; this also contributes to loss of cold air during the summer season.
