Medium Duty MDF Hardboard Door — 900mm × 2032mm
This Medium Duty MDF Hardboard Door is one of the most widely specified interior doors in South African residential and commercial construction. At 900mm wide, it meets the minimum clear opening requirement for wheelchair-accessible doorways under South Africa's National Building Regulations, making it a standard choice for accessible bathrooms, en-suites, and passage doorways in inclusive builds.
Constructed with an internal pine framework and a plain MDF skin on both faces, this door offers greater strength and impact resistance than traditional Masonite-skinned doors, while remaining lightweight enough for easy handling and installation.
Key Features
-
Plain MDF skin (both sides) – Stronger and more durable than traditional Masonite skins; smooth surface for an even paint finish
-
Internal pine framework – Structural timber frame provides rigidity and solid fixing points for hinges, locks, and closers
-
Exposed wooden edges – Standard medium-duty construction; seal edges before painting to prevent moisture absorption
-
900mm width – Meets the minimum accessible doorway width under SANS 10400-S and is widely used for wheelchair-accessible rooms

Why the 900mm Width Matters
Under SANS 10400-S (Facilities for Persons with Disabilities), a minimum clear opening width of 850mm is required for accessible doorways, with 900mm being the widely adopted standard in South African construction. A 900mm door leaf installed in a correctly sized frame provides the full clear opening needed for standard wheelchairs, mobility aids, and assistive devices. This makes the 900 × 2032mm door the default specification for accessible bathrooms, en-suites, and any doorway on an accessible route in both residential and commercial buildings.
MDF Skin vs Traditional Masonite — What's the Difference?
Traditional Masonite (hardboard) skins are thin and relatively brittle, making them susceptible to dents and surface damage. MDF skins are denser, more uniform, and significantly more impact-resistant, resulting in a door that holds up better in high-traffic environments and maintains a smoother surface over time. MDF also accepts paint more evenly, reducing the number of coats needed for a quality finish.
Ideal Applications
- Wheelchair-accessible bathrooms and en-suites
- Accessible doorways on compliant routes in residential and commercial buildings
- Bedrooms, passages, and living areas requiring a wider door opening
- Rental properties, retirement villages, and care facilities
- Medium-traffic interior doorways in offices and commercial spaces
Finishing Tips
Seal all edges — including the top, bottom, and exposed side edges — with a dedicated MDF primer or edge sealer before painting. Apply two coats of acrylic or enamel paint for a durable, washable finish. Do not use oil-based stains as MDF has no wood grain and will not absorb them evenly.

Frequently Asked Questions
Is a 900mm door wheelchair accessible?
Yes. Under SANS 10400-S, a minimum clear opening of 850mm is required for accessible doorways. A 900mm door leaf in a standard frame provides the full clear opening needed for wheelchairs and mobility aids, making it the standard specification for accessible rooms in South African residential and commercial buildings.
Can MDF doors be used in wet areas such as bathrooms?
MDF doors are suitable for bathroom doorways (not inside wet rooms) provided all edges — top, bottom, and sides — are properly sealed with an MDF primer or edge sealer before painting. Unsealed edges will absorb moisture and swell over time. For high-humidity environments, ensure adequate ventilation in the room.
What is the difference between a medium duty and a heavy duty interior door?
Medium duty doors have a standard internal pine framework with MDF or hardboard skins and are suited to normal residential and light commercial use. Heavy duty doors have a denser core construction — typically a solid timber or LVL (laminated veneer lumber) framework — providing greater rigidity, better sound attenuation, and improved resistance to impact and warping. Heavy duty doors are recommended for high-traffic commercial environments or where a closer is fitted.
Does this door come pre-primed or pre-painted?
No. The door is supplied with a plain MDF skin that must be primed and painted on site. Apply a dedicated MDF primer to all faces and edges before finishing with two coats of acrylic or enamel paint.
