Office Fire Door FAQs

Find answers to common questions about our commercial fire doors here.

How do I choose between FD30 & FD60 fire-rated doors for my commercial building?

Your choice depends on your specific building layout and fire safety strategy. Here’s how our commercial fire doors compare:

• FD30 doors provide 30 minutes of protection and are usually 44 mm to 45mm in thickness.

• One-hour FD60 doors are 54 mm thick and built for high-risk areas in commercial buildings, often priced higher due to specialised construction methods. 

Tip: Always check your fire risk assessment to ensure you meet the required safety standards for your specific location and building use.

What should I know about fitting fire doors for office buildings?

As we do not offer installations, we recommend using a specialist to ensure your fire-rated door meets all safety standards. 

To provide effective fire resistance:

• Every door requires approved intumescent strips and smoke seals fitted within the frame.

• The frame material and specific section sizes must comply with regulations to maintain the door's integrity. 

• Essential fire door hardware, including hinges, locks and door handles, must have individual test evidence proving they are fit for purpose.

Fitting tip: Pay close attention to the designated hinge and lock sides, as some doors have very small frames at the edges.

Why are fire-rated doors important for modern commercial office interiors? 

More than just a legal checkbox for your commercial space, installing fire doors is a fundamental step in protecting lives and livelihoods. Beyond providing vital fire resistance, these doors help keep your workspace secure and contained during an emergency.

Modern commercial designs prove that safety can be stylish. A contemporary fire door also offers significant noise reduction, helping to maintain a quiet, productive interior environment. 

Ultimately, commercial fire doors are essential tools for any landlord or business owner who wants to combine reliable protection with a professional look.

How do I maintain commercial fire doors?

Consistent door care is vital to ensuring your commercial fire doors remain legally compliant and fully functional. We recommend thoroughly inspecting your fire-rated doors every six months to identify any wear or potential safety risks:

1. Check that the intumescent seals are intact and that the door closes firmly into the frame without sticking. 

2. Ensure all hinges are secure and that the self-closing device operates smoothly from any angle. 

3. Clean regularly with a soft, damp cloth to keep the finish looking professional without damaging the protective materials.
