Locate electrical outlet boxes near the water fountains. This will allow you to use water warmers if you raise birds in cold weather. The outlets should be high enough that the birds can't reach them, and yet close enough to the waterers that long extension cords aren't necessary. Ceiling outlets often work well. Insulation Insulation is any material that reduces the rate that heat is transferred from inside the brooder house to the outside, or the opposite in summer.
All building materials have some insulation value.
Normal construction materials such as wood or tin do not provide enough insulation, however, and should be supplemented with materials high in insulation value. The extra or added insulation material is normally installed inside the house. Insulation serves several functions. It conserves heat in the brooder during cold weather, and reduces the rate of heat build-up in hot weather. As a result, an insulated building is cooler in the warm part of the afternoon and warmer in the cold early morning hours.
