2.6.3 Connecting standard or insulated flexible sleeves
Flexible sleeves are available in the standard version (one layer of glass fibre, fire resistance rating M0) or insulated version (two layers of glass fibre,
insulated with a 5 mm glass wool felt), supplied with 4 M8 screws, 8 washers and 4 nuts. The sleeve may be fixed to a damper or directly to the opening
frames. For sleeve dimensions, refer to section 3.2.1.
Screw each flexible sleeve into the inserts of the opening frame or on to the insulation dampers, by fitting the washer, screw and nut in each assembly
corner. Insulate the ducts in accordance with applicable standards and regulations.
