Whilst it is impossible to account for all scenarios, the following act as general guides:
50mm thick
These thicknesses may not satisfy all criteria and design requirements.
Warm air ducts
BS5422:2009 (table 13) - Control Heat Loss
Whilst it is impossible to account for all scenarios, the following act as general guides:
Within Building 40mm thick, Plant rooms & external locations 50mm thick
These thicknesses may not satisfy all criteria and design requirements.
Chilled air in ambient conditions
BS5422:2009 (table 12) - Condensation Control
Whilst it is impossible to account for all scenarios, the following act as general guides:
