U-value calculator
Choose a typical wall construction or build your own, and compare the calculated U-value with and without PS Coat.
Wall construction
Layer buildup (interior → exterior)
PS Coat 1 mm
PS Coat – always included as the final layer (fixed thickness: 1 mm).

With PS Coat
—
W/(m²K)
Improvement from PS Coat
Simplified layer calculation per DIN EN ISO 6946 (Rsi = 0.13, Rse = 0.04 m²K/W), not accounting for thermal bridges or stud-cavity fractions.
