Installation situation
I want to use my own installation values
Ψ_up= W/(mK) Ψ_down= W/(mK)	Ψ_left= W/(mK) Ψ_right= W/(mK)
Or select certified situation:	`U`_{W, installed} = ? W/(m² K)

U-value calculation
	`b₁`  m	`b₂`  m	`b₃`  m
`h_top`  m `h_bottom`  m				Glazing `U`_g  W/(m² K) G-value
	`U`_W = ? W/(m² K)
