Custom Roof Hatches Available To Meet Any Access Requirement


NEW HAVEN, CT – The Bilco Company’s Type D double leaf roof hatch features a large opening that allows equipment to be easily installed or removed from a building. Roof Hatches are custom fabricated to meet virtually any access opening requirement. While Type D roof hatches have been available since the 1950s, technical advances over the years have allowed for the manufacture of extremely large hatches that are both durable and safe to operate. These improvements have led to a broader use of the product in a wide variety of applications while satisfying a number of unique access requirements. Hospitals have utilized this roof hatch for the installation of large MRI facility and to provide easy access to this equipment for repairs or replacement. Manufacturing facilities are using equipment access hatches to bring large pieces of processing equipment into a building. In addition, hatches have also been used to lower air handling equipment into the top floor of high-rise buildings. More commonly, the large access opening of the Type D roof hatch is often used to bring equipment through the building and onto the roof for installation during building construction. Type D Equipment Access roof hatches are designed for weathertight performance and safe and easy operation regardless of the cover size and weight. Products feature full EPDM gasketing, insulated covers and curb and an overlapping cover design to ensure energy efficiency and performance. Each product is designed with lift assist that is specifically engineered to the cover size and weight to allow for easy, one-hand operation.
