Start here: which DS 452 class must the installation meet?
How thick should the insulation be — and what does the pipe lose?
How thick should the insulation be?
Choose energy class 1–6 as the target — the calculator finds the smallest thickness that meets the requirement with your chosen material and pipe dimension.
What does the pipe lose — and what does it cost?
Calculate heat loss per EN ISO 12241 from medium temperature, dimension, thickness and λ-value. Also get surface temperature and annual operating economy.
How much insulation and jacketing do I need?
Calculate m² of insulation and jacket/sheet for pipes and rectangular ducts — multiple layers (each on its own outer dimension), waste allowance and overlap. For material ordering and quotations.
Hvor meget isolering skal der i kanalen?
Ren geometri: indtast en firkantet kanals længde, bredde, højde og isoleringstykkelse — få rumfanget af isolering (m³), de ydre mål og den ydre overflade til pladekappe-bestilling.
Check an existing installation: achieved class and condensation risk.
Which class does your installation reach?
Enter the existing thickness — the calculator classifies the installation into DS 452 class 1–6 and shows how far you are from the next class.
Is there a risk of condensation?
Enter temperature and relative humidity — get the dew-point temperature and an assessment of whether the surface sweats. A must for cold pipes.
Hvad sparer jeg ved at gå fra klasse X til Y?
Sammenlign det maks. tilladte varmetab mellem to DS 452-klasser på samme rør — få besparelsen pr. meter, den årlige energibesparelse og en CO₂-reduktion (med din egen, vejledende emissionsfaktor).
U-value for layered, flat constructions.
