Hardware, Doors and Access Design Guidelines
Entrances – General
All doors, hardware, closers, etc., shall provide means for easy access and use by the physically handicapped.
Doors – Wood and Metal
- Except in special situations, the minimum door opening is 36″.
- Use flush doors wherever practical.
- Transparent finished wood doors shall be satin finished where practical. Seal tops and edges with WaterLox or equivalent immediately after trimming.
- For non-fire rated doors, use only solid-core wood doors similar and equal to Weyerhaeuser, Code DSC-1.
- Fire rated doors which are required to be B-label should be metal, in order to minimize the weight which the hinges and closers must carry. However, if B-label wood doors are specified, they shall have hinges and door closers installed using through-bolt hardware. Hardware, otherwise capable of handling the unusual weight.
- On labeled fire doors, all closers shall be UL listed non-hold open type.
- Doors which open to corridors and which contain glass, shall use either 1/4″ UL fire-rated tempered glass or 1/4″ wire glass set in rated metal frames with wire strands running diagonally.
- Provide automatic door openers as required in the Accessibility Section IV – D.
- Whenever possible, avoid fire shutter doors. If fire shutter doors are required, they shall be motor operated Up and Down. Provide access to the controls and all reset features from floor level. The test and reset connections to the fire alarm system should be key operated.
- All exterior doors shall have a minimum of 36″ opening and 7’0″ height.
- Double doors generally should not be used because of the problems involved in securing these doors. Where double doors are required, provide a keyed removable mullion such as Von duprin #5754.
- All exterior doors and jambs should be hollow metal (steel) or aluminum and glass (storefront systems). Wood and frameless glass exterior doors present a severe maintenance problem and should be avoided. Steel doors shall be a minimum of 16 gauge steel; jambs shall be a minimum of 14 gauge. Aluminum doors in store front systems shall be medium or wide stile; narrow stile doors are not acceptable.
- At each accessible entrance to a building equip at least one door with an automatic door operator. Refer to accessibility Section IV – D for additional requirements.
- Completely protect all exterior automatic door operator activators provided at accessible entrances from the weather. This shall include not only the use of weatherproof electrical boxes and enclosures, but also must contain a weatherproof activator (rubber seal or push button) or housing which will prevent water from entering around the switch and prevent sticking during freezing weather.
Provide access doors equal to Milcor Style ‘K’ or ‘DW’.
Windows – Wood and Metal
Construct window sections to enable cleaning of outside glass surfaces from inside the building (in-swing, removable, or pivoted) except for windows accessible from the ground and windows no higher than forty feet (40′) above grade. Equip window sections with concealed locks and removable keys. (For fire department access and emergency escape certain buildings and windows are required to be operable from within, without special use of a key.) Turn all keys over to Facilities Services with a minimum of one key per each 30 windows. Provide double-glazed windows with vacuum seal and 1/4″ minimum, clear, polished glass.
