Curtain fabric
The MDFS 120+ fabric is a woven glass fibre fabric, reinforced with stainless steel wire and coated on both sides with a specially formulated micronised aluminium polymer, which provides an effective heat reflective surface as well as other properties required for material used in the manufacture of smoke and fire curtains MDFS 120+ fabric complies fully with the requirements of BS7346 part 3 1990

Bottom Rail
A (T) section bottom rail is attached to the curtain to assist downwards movement which will also stop at ceiling level for aesthetic value

Roller
The curtain fabric coils onto a tubular 70mm barrel mounted on endplate bearings

Coil Casing
The barrel and curtain are housed in a 1.2mm thick galvanised head box

Guides
Fire curtains require guides to provide a seal between the fabric and building structure. The nature of a fire causes pressures to act on the curtain fabric that could dislodge the fabric from the guides. MDFS1 fire curtains incorporate a unique retaining system to prevent this occurrence.

Finish
The coil casing, bottom rail and guides are galvanised as standard. Alternatively, they can be polyester powder coated for visual effect
