Fire Retardant (BS5852 Part 2 Type B & C)

Fire Retardant All of the fabrics available from us are inherently fire retardant, and come with full fabric Fire Retardant certification.

Curtains Including Sheers

There are no requirements for flame retardancy of any drapes used in a domestic or private residential environment. Any drape used in a contract setting is subject to flame retardant requirements.

BS5867 Part 2 Type B

Hotels, Public Buildings and Offices

  • Face Ignition test (Flame applied for 15 seconds).
  • Pass = Flame does not reach any edge of fabric test piece.
  • Pass = No flaming debris from fabric test piece.

BS5867 Part 2 Type C

Hospitals and Healthcare Environments

  • Face and Back Ignition test (flame applied for a range of application times).
  • Wash requirement to 50 washes (for FR treated fabrics).
  • Pass = Any resultant afterflame must cease within 2.5 secs.

BS EN13773

Harmonised European Standard

  • Edge ignition test with Radiant heat source applied to the fabric test piece.

Marine Standard: IMO A.471 (Xii)/A.563 (14)

  • Edge and Face ignition test (flame applied for 5 and 15 second intervals).
  • Pass = Any resultant afterflame must cease within 5 seconds.


Bedding Items & Beds

Under domestic regulations only the product filling for bedding items requires to be tested. Under contract regulations these are the following standards which may be considered for the fabric being used:


For Bed Covers and Bedthrows

  • Cigarette, Match and Crib ignition sources are used to satisfy the safety level based on a risk assessment.

Marine Standard IMO A.688 (17)

  • Cigarette and Match ignition sources are used with additional fuel source (increasing the harshness) in the form of a cotton pad on top of the flame source.

BS EN ISO 12952 – 1/2

  • Cigarette and Match ignition source are used for assessment of ignitability of bedding items.


For Bed Bases and Mattresses

  • Performance standard including three levels of hazard: Low, Medium and High
  • Low Hazard | Cigarette and Match | Domestic
  • Medium Hazard | Cigarette, Match and Crib 5 | Hotels and some Healthcare
  • High Hazard | Cigarette, Match and Crib 7 | Prisons and some Hospitals


Positives & Negatives

All fabrics have positive and negative characteristics. Sometimes, properties that appear negative are not important because they are not required for a particular end use. Correct specification of a fabric is crucial to avoid unsatisfactory performance. Listed below are some of the main attributes of FR inherent and FR treated fabrics.

Inherently FR Polyester Fabrics

Such As Trevira CS


  • A large number of fabric weights and constructions available offering many possible applications.
  • Inherently FR with no additional chemical treatments.
  • Enduring and permanant with no aggressive chemicals.
  • Very low emission of fumes.
  • Recyclable and environmentally friendly.
  • Very strong relative to weight.
  • Easy Care.
  • Durable to washing at high temperatures


  • The fabric can pill if not manufactured correctly.
  • Will not form a char barrier during FR testing.
  • It is not a natural product.

FR Treated Cotton Fabrics


  • FR treatments can be easily applied by a pad and baking process and applicable to all cellulose fabrics including viscose.
  • Acts as a char barrier during FR testing.
  • Natural and sustainable.


  • Can be stiffer with lower drape characteristics.
  • Can cause skin irritation in certain circumstances.
  • Additional chemical treatments mean additional cost.
  • High emission of fumes.
  • Additional chemical application can reduce tensile strength.
  • Fabric can be susceptible to additional shrinkage when washed.

Modacrylic Blended Fabrics

Such as Kanecaron


  • Good handle, natural feel.
  • Inherently flame retardant with no additional chemical treatments.
  • Acts as a char barrier during FR testing.


  • Limited yarns and yarn count availability.
  • Less durability, Modacrylic can be susceptible to pilling dependent  upon fibre percentage.
  • Fabric can be susceptible to additional shrinkage when washed.

FR Backcoated Fabrics

For Upholstery or Blackout Curtains


  • Can be easily applied.
  • Can be applied to a large number of fabric qualities.
  • Face appearance is unaffected by the backcoating process.
  • Creates ‘blackout’ when applied to curtains.


  • Not all fabrics are suitable for backcoating.
  • Does not guarantee flame retardancy of all fabric blends.
  • Not always durable to washing.

Wool Fabrics


  • Natural and sustainable.
  • Strong relative to weight.
  • Strong durability.
  • Acts as a char barrier during FR testing.


  • Not inherently FR to all requirements.
  • Can pill depending upon processing.
  • Fewer fabric constructions available.
  • Generally and comparably expensive.
  • Not easy care.
