Question 1

1. What is a fire door blank for?

Accepted Answer

A fire door blank is a solid-core timber door leaf used as the base for creating a fire-resisting doorset. Builders use it when they need to modify or finish the door on site—such as cutting it to fit, adding vision panels, or routing for ironmongery. Fire door blanks allow for more flexibility in installation while still achieving the required fire resistance when correctly assembled with certified components.

Question 2

2. Can fire door blanks be cut down?

Accepted Answer

Yes, but always within the limitations set by the product’s fire certification. Most manufacturers specify maximum trimming allowances for edges and tops or bottoms. Exceeding these limits can reduce the door’s ability to contain fire and may invalidate compliance with building regulations. Always refer to the manufacturer’s technical data before modifying the blank.

Question 3

3. Are fire door blanks rated?

Accepted Answer

Yes. Fire door blanks are tested to provide fire resistance for a specified duration, commonly 30 or 60 minutes. The rating depends on the core material, thickness, and how the door is installed as part of a complete system. For example, 60-minute fire door blanks must be fitted with compatible frames, seals, and hardware to achieve their stated performance in a real fire.
