- § 06Which DS 452 class must my installation comply with?
- § 04How thick must the insulation be to hit a specific class?
- § 01How much heat does the pipe lose per metre — and what does it cost per year?
- § 05Which class does the thickness I already have meet?
- § 03Is the surface sweating — is there a risk of condensation on a cold pipe?
- § 02What is the U-value for a duct or tank wall with several layers?
- § 07How many m² of insulation and jacketing should I order for the job?
- § 08How many m³ of insulation do I need for a square duct?
- § 09How much less may the pipe lose if I tighten the DS 452 class?
- § 10How much does the temperature drop from start to end of the pipe section?
- § 11How much does the insulation save — and how quickly is the investment paid back?
- § 12How long before the water in the pipe freezes in frost weather?
- § 13How hot is the tank after X hours — and when does it reach the required temperature?
- § VCan I be taken through the entire insulation specification at once?
Step V — Directory
Be guided through the entire work process all at once — from pipe to finished spec.
Step A — Find requirement
Start here: which DS 452 class must the installation meet?
Step B — Size it
How thick should the insulation be — and what does the pipe lose?
Step C — Check
Check an existing installation: achieved class and condensation risk.
Energy class
Which class does your installation reach?
Dew point
Is there a risk of condensation?
Heat loss class comparison
What do I save by going from class X to Y?
Temperature drop in pipe with flow
How hot is the medium when it reaches?
Energy savings & reimbursement
What does the insulation save — and when is it paid back?
Freezing time for water-filled pipe
Hours before 0 °C — and before ice
Step D — Surfaces & tanks
U-value for layered, flat constructions.
