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
