U values for sliding door Artline
Formula for calculating the total U value of a sliding door, taking into account the glazing unit, the share of profiles and an edge zone effect linear factor.
Usliding door = ( Ag * Ug + Af * Uf + Ig * ψg ) / ( Ag + Af )
The calculations are based on the requirements and general guidelines.
