Curtain Fireproofing FAQs
How long does the treatment take?
Most jobs are completed within a few hours, so your venue is usually ready to use the same day. (Book early to secure your preferred date.)
When will I receive the fire safety certificate?
Your Certificate of Fire Retardant Treatment is issued immediately upon payment and confirms compliance with BS 5867 Part 2 Type B.
How long does the fire retardant treatment last?
Certification remains valid for up to five years or five dry cleaning cycles, whichever comes first. Retreatment is necessary if curtains are laundered.
How do I know if my curtains are already compliant?
If there is no BS 5867 Part 2 Type B label or certificate, the curtains will usually require treatment, or if a period of 5 years has past since the last treatment.
Will the treatment damage or mark the fabric?
We use a professional, water-based fire retardant suitable for most fabrics; sample testing is recommended for delicate materials.
Do domestic curtains need fire retardant treatment?
No. Fire retardant treatment applies only to public and commercial spaces, not private homes.
