Compliance
• Semi Rigid Ducting performance
data is now recognised in SAP via
Appendix Q.
• Considered as ‘equal to’ rigid duct
• Only duct systems that feature on
the SAP Appendix Q website have
been tested and validated
• Initially for MVHR systems, MEV
testing will be completed early next
year

COMPLIANCE GUIDE
The Problem…
Installation: • Supplied on a roll, 75mm dia flexible
pipe
• Radial design goes direct to room
• Considerable savings on installation
time
• Compatible with i joist, metal web and
concrete screeds
• Easy to run through narrow gaps
The Solution…SEMI RIGID DUCTING
WHY?
Performance: • Limits noise transmission between
rooms
• High crushability typically up to 16
kN/m2
• Low resistance pipe compared to
flexible
