DD/SR 60 – 120 DURADUCT Steel Run-Out Ducting

A steel duct system tested to BS 476:Part 24, built to enhanced DW144 standards/SMACNA, it provides 60 or 120 minutes stability/integrity. This ducting is for use together with the DD/SMT and DD/LT ranges for connection largely between the main smoke extract system and grilles where fire insulation performance is not required.

Additionally, the system may be used for smaller cross-section extract ducts that are located within protected shafts. These shafts provide the required fire compartmentation and aesthetic finishes, such as those often used for toilet extract ducting.

Performance

The DD/SR Range has been tested to:

	BS 476: Part 24: 1987 and meets the fire stability and integrity requirements for up to 120 minutes.
	It maintains minimal 75% cross-section required by BS 476: Part 24 : 1987 and is suitable for smoke extract ducting.
	Air Leakage A -C (DW144).

Please note: The cross section of the DD/SR duct system is limited to 0.2m² with no side greater than 0.75 metres wide. Ducts outside this range are manufactured from DURASTEEL^®.
