Finding the right fire rated door is an important part of planning a safe interior space. DoorCart offers a selection of prehung fire rated doors designed for residential, multi-family, renovation, and commercial applications across Canada. Our collection includes different styles, sizes, and fire ratings so you can choose a door that suits both the requirements of your project and the appearance of your interior.
A prehung fire rated door combines the door slab with a compatible frame and hinges, providing a convenient option when the complete opening needs to be replaced or installed. Depending on the product, fire-rated options may include tested and certified components designed to provide resistance to fire exposure for a specified period.
When selecting a fire rated door, the correct rating, size, frame, hardware, certification, and installation method should always be considered together. Building requirements can vary depending on the location and type of property, so confirm the requirements for your particular project before ordering.
Shop Prehung Fire Rated Doors in Canada
DoorCart’s collection of prehung fire rated doors gives homeowners, contractors, builders, renovators, and property managers access to practical fire-rated interior door solutions.
A prehung configuration can make installation more convenient because the door is already mounted in its frame. Instead of purchasing a door slab separately and finding a compatible frame, a prehung unit provides the major components together.
Our selection includes several interior styles, including flush, shaker, panel, and arch designs. This means a fire rated door does not have to look out of place in an attractive interior. You can choose a practical fire-rated solution while maintaining the design style of your home, apartment, office, or commercial space.

What Is a Prehung Fire Rated Door?
A prehung fire rated door is a door assembly supplied with the door mounted within a frame. The assembly can include the door slab, frame, hinges, and other components required for the particular product.
This differs from a slab fire rated door, where the door panel is supplied separately and requires an appropriate compatible frame and hardware.
A prehung configuration can be particularly useful during new construction or renovation projects where the existing frame is being removed. It can also simplify the process of replacing an entire opening.
However, fire-rated performance depends on the complete tested assembly and proper installation. A fire rated door should therefore be installed according to the manufacturer’s requirements rather than treated like an ordinary interior door.
Why Choose a Fire Rated Interior Door?
Fire-rated doors are designed for applications where an opening needs additional protection against fire for a specified period. When correctly selected and installed, a certified fire-rated assembly can help slow the movement of fire and smoke between areas.
Depending on the building and application, fire rated interior doors may be considered for:
- Attached garage entrances
- Basement areas
- Utility and mechanical rooms
- Apartment buildings
- Multi-family properties
- Stairwell areas
- Corridors
- Commercial buildings
- Other openings forming part of a required fire separation
The required rating is not the same for every application. A residential opening may have different requirements from a commercial corridor or stairwell, which is why the applicable building requirements should be confirmed before purchasing.
20 Minute Fire Rated Doors
A 20 minute fire rated door is one of the common options available for interior applications. These doors are tested to provide a specified level of fire resistance during standardized testing.
At DoorCart, several prehung fire rated products are available in 20-minute configurations, including different panel and flush styles.
A 20-minute option may be suitable for certain residential and interior applications, but the required rating should always be determined by the specific opening and applicable building requirements.
If you are researching 20-minute options, read our guide to 20 Minute Fire Rated Doors for Homes and Interiors to learn more about ratings, applications, and selection considerations.
45, 60 and 90 Minute Fire Rated Doors
Not every project requires the same fire resistance rating.
Depending on the building design and required fire separation, projects may call for 45-minute, 60-minute, or 90-minute fire rated assemblies.
A 90 minute fire rated door, for example, provides a longer tested fire-resistance period than a 20-minute assembly and may be used in applications with more demanding fire-separation requirements.
DoorCart also offers a dedicated 90 Minute Fire Rated Doors category where you can explore products specifically associated with this rating.
Do not select a rating simply because it is higher. The appropriate rating should match the requirements of the opening, wall assembly, building design, and applicable regulations.
Prehung vs. Slab Fire Rated Doors
One of the first decisions when purchasing a fire rated door is whether you need a prehung unit or a slab.
Prehung Fire Rated Door
A prehung unit includes the door mounted in its frame. This can be a convenient choice when replacing the complete door opening or during new construction.
Slab Fire Rated Door
A slab fire rated door consists primarily of the door panel. It can be appropriate when you already have a suitable compatible frame or when a project is designed around a replacement slab.
DoorCart also offers a dedicated Slab Fire Rated Doors collection with options such as flush and panel designs.
The correct choice depends on your existing opening, frame, hardware, installation requirements, and project specifications.
Fire Rated Door and Frame
The frame is an important part of a fire-rated opening.
A certified fire rated door should not automatically be installed into any standard interior frame. The door, frame, hardware, hinges, seals, and other components may need to be compatible with the tested assembly.
This is one reason a prehung fire rated door can be convenient for certain projects. The main door and frame components are supplied together, making it easier to select a complete configuration.
Before installation, always check the manufacturer’s requirements for the specific door assembly.
Fire Rated Door Styles
Safety and interior design do not necessarily have to be separate considerations.
DoorCart’s prehung fire rated collection includes several styles that can work with different interior designs.
Flush Fire Rated Doors
Flush doors provide a clean and simple appearance. They can work particularly well in modern, minimalist, utility, and commercial interiors.
Shaker Fire Rated Doors
Shaker designs provide a more traditional or contemporary appearance while maintaining the practical requirements of a fire-rated interior door.
Panel Fire Rated Doors
Panel configurations can provide additional visual detail for homes, apartments, offices, and renovation projects where the door should coordinate with other interior doors.
Arch Fire Rated Doors
A two-panel arch design can provide a more decorative appearance while still being available as a fire-rated interior door option.
When choosing a style, make sure the specific product meets the fire rating and configuration required for your project.
Where Are Prehung Fire Rated Doors Used?
The correct application depends on the building and applicable requirements, but prehung fire rated doors can be considered for a variety of interior projects.
Residential Projects
Homeowners may need fire-rated openings around garages, basements, mechanical areas, or other locations depending on the design and applicable requirements.
Apartments and Multi-Family Buildings
Multi-unit properties often have multiple areas where fire separation is an important consideration. Fire-rated interior doors may be used around units, corridors, stairways, and service areas where required.
Commercial Buildings
Offices, retail spaces, industrial properties, and other commercial buildings can have different fire-separation requirements. The correct door rating should be established from the project’s specifications.
How to Choose the Right Fire Rated Door
Before ordering a fire rated door, consider the following:
1. Determine the required fire rating
Find out whether the opening requires a 20, 45, 60, 90-minute, or another rating.
2. Measure the opening
Confirm the required width, height, jamb depth, and swing direction.
3. Choose prehung or slab
If you are replacing the entire frame, a prehung configuration may be the more convenient option.
4. Check certification
Review the individual product specifications for the applicable certification and rating.
5. Confirm frame requirements
Make sure the frame and other components are compatible with the selected fire rated door.
6. Follow installation requirements
Proper installation is essential for the tested performance of a fire-rated assembly.
If you are uncertain about the rating or configuration required for your project, consult the applicable building authority, contractor, architect, or other qualified professional.
