Choosing the Right Unfinished Fire Door

When picking an unfinished fire door, it helps to think about what works best for your space. Start by choosing the fire rating — FD30 for 30-minute protection or FD60 for 60-minute protection — depending on the regulations for your building. Check the door size too; standard measurements work for most homes, but we also offer bespoke sizing for more unique openings. Because these doors require finishing, consider which style will best match the look you want to achieve once painted or stained.

And of course, be sure the door meets all required building and fire safety regulations. If you're unsure about anything, don’t worry — our friendly team is always happy to offer advice and help you choose the ideal unfinished fire door for your project.
