– “Safety Stress” method was used in calculations. Self-weight, live load (wind load) and heat change (Δt = ± 20ºC) are taken into account.
– L / 200 and L / 150 are taken if the deflection limit acts as a pressure, and L / 150 if it acts as a suction.
– Sheet quality is based on fγ = 240 MPa (Yield Strength).
– In the panel weight calculation, Polyurethane (PUR) density is taken as 40 kg / m³, Polyisocyanurate (PIR) density is taken as 42 kg / m³.
