Custom Door Installation NYC

Our new project is a custom door installation  NYC for the Bishop Joseph M. Sullivan Residence in Brooklyn provides permanent housing with support in a single-site building with 24-hour staff support for adults with serious mental illness, co-occurring mental illness and substance abuse disorders and adults with HIV/AIDS. Tenants are provided with rental stipends and case management/supportive services on an as-needed basis. Tenants pay 30% of gross monthly income towards rent that shelters people with special needs. These doors are for very heavy traffic. Exterior fronts also have an added element for wind and cold weather. The doors are aluminum to match the building’s original design (the vision glass around the doors).

Type of Door Install:

Clear anodize aluminum

Frame 2×4 1/2″

Doors wide style 5″ around vision

10″ bottom rail

Door Hardware Installation:

Full mortise continuo hinges double Bering heavy duty

Von duprin push to exit device

Aromatic heavy duty door closer norton 6000


Security desk can open and swing doors remotely

Wheel chair can push button to swing doors (not manually for easy excess)

Original doors were double doors, we changed to a single door. The existing doors were not good for heavy traffic. When there is an additional entrance in a building such as Service Entrance (service entrances are always double doors and are used for deliveries or similar services)  and if the front door needs to be automatic, it should be a single door. Single doors are the best solution for wheel chair accessibility which was the case for this building with many wheel chairs coming in and out all the time.

New doors were replaced with Center single door 42″ (more the standard 36″) more convenient for smooth access in and out especially on wheel chair.

Fire Rated Doors


Components: Style &Types

Fire-rated doors are made in a variety of styles and come as a completed assembly including the frame and associated hardware, such as hinges, a latch, lock or the required closing device. Dori Doors in NYC installs fire rated doors that meet NYC codes. We also correct code violations with onsite repairs.

These doors are offered from stock on hand from manufacturers who also assist in developing the best door to suit any particular need. Among these are:

  • Hollow metal doors—typically installed on the building exterior and built to withstand the elements. These doors are also used in stairwells, on elevators and for janitor’s closets where moisture is often an issue.
  • Wood doors—providing a natural complement to a building’s architecture. Wood doors are produced from a variety of species allowing for the choice of stain options. Other options include bullet proofing, lead lining or acoustical treatment.
  • Fiberglass doors—best suited for harsh environments such as pools, water treatment facilities and chemical, manufacturing or sewage plants where the doors need to resist splitting, warping or rotting.

The National Fire Protection Association (NFPA) outlines the methodology used in determining fire-resistance ratings. Basically, ratings indicate an hourly duration of exposure to fire and its intensity. Testing fire-rated doors calls for exposing the door to its prescribed duration of fire exposure while it is mounted in the wall of a test furnace. This controlled fire conforms to the standard time-temperature curve and is applied to only one side of the door. The test ends either at the point of passing having reached the expected fire protection rating or at the point of failure.

Benefits of Installing Fire-Rated Doors

There are numerous benefits gained by installing fire-rated doors, including:

  • Slowing down the progression of a fire sufficiently to allow occupants safe egress
  • Providing a fire barrier that retards the spread of fire for a specific time limit
  • Limiting the spread of heat, smoke and toxic gases
  • Limiting the extent of fire damage

The purpose of fire-rated doors is to prevent smoke and flames from spreading throughout a building in the event of a fire. The doors must be closed during a fire to be effective. In this way, fire is compartmentalized allowing occupants the time needed to safely evacuate the building. The fire rating correlates to the amount of time the door will hold back the fire providing from 20 to 180 minutes egress route protection as designated by a letter code.

Fire-Rated Door Installation NYC

Dori Doors NYC is the leading door Installation Company for fire rated doors.

Fire rated doors are required for emergency exits, boiler rooms, and apartment front doors in NYC. Fire rated doors are also available with decorative recessed panels which can be painted. Dori Doors also carries fire rated doors in different finishes. There are a number of factors to pay attention to in the installation of fire-rated doors to ensure they keep their rating upon inspection. Doors need to be self-closing and self-latching with the appropriate fire-labeled hardware installed. Gaskets and edge seals need to be intact to prevent any gaps when the doors are closed. No part of the required fire-rated label can be painted over.

Fire-Rated Door Repair NYC

To ensure safety of occupants and property protection, it is important to have skilled technicians install and repair fire-rated doors. An insured contractor brings the technical knowledge to the job of making sure fire-rated doors are working as they have been designed and are maintained in a manner that keeps their rating in accordance with NFPA Standards.
