A bulkhead door is a very convenient addition to a basement, allowing a direct access to the outside and providing a larger opening than a regular door. Common bulkhead doors are wide enough to store large lawn furniture and provide enough space to install and service a complete boiler or HVAC system without the need of disassembling larger components.Most bulkhead doors are made of steel or
. wood. These materials are heavy, expensive and require periodic maintenance, such as painting and rust removal. Some modern models are now made of fiberglass, a much more durable and versatile material, that offers the same strength as steel at a fraction of the price and weight.Fiberglass is molded to any shape required and with minimal adaptations, a manufacturer can provide a custom fit bulkhead. Different types of finishing are later applied, some to resemble corrugated steel or even hardwood, complete with grain and texture.The most common type of fiberglass bulkhead door, or basement cellar door, has two half doors equipped with torsion systems or hinges that lock when open, providing a safety mechanism against a door accidentally closing. On the inside, padlock eyelets, locks and slide bolts provide a safe locking system.Because of their reduced weight, fiberglass bulkhead doors are much easier to open and close. This feature, along with the great resistance to elements and strength makes them a very good choice for storm shelter doors, as they provide safety but are easily operated by even the weakest.A common feature of this type of door is the integrated sealant and insulation that prevent condensation or water leakage during rain or snow. As the doors are lighter, these systems are easily installed during manufacturing, making the installation procedure faster and more affordable, as only a small frame is mounted over the basement access and the complete bulkhead is later fixed with stainless steel screws or bolts.More reference links: http://www.paramountfiberglass.net/Paramount%20Fiberglass%20Specialties,%20Inc._files/Page387.htm http://www.homeadditionplus.com/basement-info/Basement-Bulkhead-Doors.htm
