During cold weather if side wall curtains do not seal tightly against the side wall cold air will be directed toward the floor chilling the birds. To minimize side wall curtain leakage:
Make sure the top of the side wall curtain overlaps the curtain opening by at least six inches. If there isn’t sufficient
curtain overlap consider attaching a 1' strip of curtain material to the top of the curtain opening to increase curtain
Make sure curtain pulleys and strapping are installed within an inch where the top of the side wall curtain sits when
closed. This helps to insure that the top of the side wall curtain will be held tightly against the side wall.
Make sure there are no metal siding ribs between the curtain pulley and the top curtain rod. A metal rib tends to
hold the curtain string approximately one inch off the side wall resulting in a loose fitting curtain.
Seal the bottom of the curtain with a wooden strip. The wooden strip not only increases curtain tightness but
minimizes the possibility of ice forming between the curtain and the side wall which tends to push the curtain off
the side wall decreasing curtain tightness. Make sure the strip is installed right at the bottom of the curtain opening
to prevent trash from collecting between the side wall and the curtain.
Install a curtain pocket at the top of the curtain opening to help insure the top of the curtain seals tightly (Poultry Housing Tips December, 1996)
