What Are Door Blanks?

Door blanks are unfinished doors that are typically made of wood, metal, or composite materials. They are designed to be customised to fit specific requirements, such as size, shape, and style. 

Door blanks are often used in new construction and renovation projects where standard-sized doors are not suitable or where a unique design is required.

They are called "blanks" because they are unfinished, with no pre-cut holes for hardware or decorative details, allowing them to be customised to meet the specific needs of different door designs.

Fire Door Blanks

Fire door blanks are essentially fire-resistant doors designed for internal use. As their name implies, these internal door blanks appear simple and plain with a sleek design that fits flush against the frame. The outer veneer is crafted from hardwood such as ash, walnut or oak veneer around a solid core for added durability.


Once the blank is cut to size, grooves are machined into the door edges and an intumescent strip is inserted by the installer (this strip does not come with the door blank). This intumescent strip encircles the frame ensuring that the assembly provides premium protection against smoke and fire. Upon reaching temperatures of around 200°C, this strip expands to block any heat from passing between the door and its frame.

The installation of a smoke seal is an excellent way to protect your family from the spread of potentially harmful fumes. These flush doors should be placed between living spaces and communal areas, such as hallways or stairwells. For maximum protection, these fire doors must be installed in combination with CE-certified hinges within the frame.

Any installation that involves fire safety should be carried out strictly in accordance with manufacturers guidance and test evidence.


Here at Materials Market, our range of fire door blanks come with a fire rating of either FD30 or FD60. 


Frequently Asked Door Blanks Questions

What Is Hardwood Lipping?

A hardwood lipping encases the door leaf to finish off the door with a robust and aesthetically acceptable detail. 

Some are intentionally left exposed for appearance, others are simply painted in with the door.

Can A Door Blank Be Cut To Size?

Yes, door blanks can be cut to size using a saw or other cutting tool. It's important to make sure the door blank is measured accurately before cutting, to ensure a proper fit.

Can A Door Blank Be Painted or Stained?

Yes, door blanks can be painted or stained to match the desired finish for a door. Solid wood blanks tend to take paint and stain better than composite blanks, but both types can be finished to match a variety of styles.

What Type of Hardware Can Be Installed on a Door Blank?

Door blanks can be customised to fit a wide range of hardware, including handles, locks, hinges, and other decorative elements. It's important to make sure the hardware is installed in the correct location and at the appropriate depth, to ensure a proper fit and function.

If a fire rating is required, the hardware must also have the appropriate rating and CE marking.

How Long Does a Door Blank Last?

The lifespan of a door blank will depend on the quality of the material used, the level of maintenance, and the environmental conditions it is exposed to. With proper care and maintenance, a high-quality door blank can last for many years.
