NELCO lead-lined window and door frames are designed to suit various wall sizes and hardware specifications, while ensuring the ultimate in radiation shielding. For facilities in the medical, industrial, scientific, and nuclear industries where radiation is present, NELCO lead-lined frames are a must-have. The window frames support lead glass or leaded acrylic, and the door frames support the heavy weight of lead-lined wood doors and have aesthetic appeal. There are two types of frames for existing and new construction, both with mitered corners for a strong, continuous seal.
