Fire Curtain / Attic Compartmentation

To provide compartmentation in the attic space of a two storey block of apartments in Ringsend County Dublin. Also to prevent the spread of fire from one unit to another using an Intumescent-coated fire curtain. Finally to provide 30 minutes protection and Class 0 spread of flame.

The roof space internally was to be upgraded using Envirograf Product 56 – Internal roof fire curtain. Designed to inhibit the spread of fire and smoke from one roof space to another. The product is fitted by two fitters working from inside the roof space following the sequence set out below.

All curtains are supplied with sufficient adhesive for the 50 mm overlap. The adhesive can be applied to one face and pressed together. Although it is best to apply a small layer to each face and apply together, giving a much quicker bond. Just hold together for approximately 1 minute, in order to allow the adhesive to grip. For fixing the top, bottom and ends of the Curtain; for timber supports use Envirograf FB/T Battens. Battens are fixed through to the timber with 30 mm large head clout nails. For concrete, block or brick fixing, use FB/C Metal Straps – 25 mm wide, with 2 mm holes every 300 mm apart. These can be fixed with spit nails, screws, pop rivets (steel) or self-tapping screws to the steel work.
