Summary and Implications
Use of roof insulation in laying-hen houses to reduce heat transfer through the roof in summertime in Iowa was assessed through modeling and field measurement. The results indicate that roof insulation is effective to reducing heat transfer through the roof, thus may help to relieve hen heat stress. One inch-thick polystyrene board (R5) is sufficient to prevent majority of the roof heat transfer
