Many steel structure factories separate roof and exterior wall construction without unified design, leading to water leakage at wall roof junction and inconsistent building appearance. Reasonable matching of sandwich panel roof and curtain wall solves these two core problems efficiently. This article provides complete matching design suggestions for industrial building envelope system.

The connection position between sandwich panel roof and curtain wall is the most common water leakage point of industrial buildings. Special transition metal pressing strips match the two materials to cover splicing gaps. Multi layer waterproof adhesive strip and foam filling block rainwater infiltration, adapting long term outdoor wind and rain exposure without aging leakage risk.

Select coating with same anti ultraviolet grade for sandwich panel roof and aluminum honeycomb curtain wall panel to guarantee consistent color fading speed. Thermal expansion coefficient of metal surface layers keeps close value to avoid cracking of sealing glue caused by temperature deformation difference. Fire grade of roof panels and curtain wall base plates maintains unified standard for whole building fire safety.

Sandwich panel roof installs on main steel beam of steel structure frame, while curtain wall fixes on vertical steel column. The reserved gap between roof edge and curtain wall top reserves thermal expansion space for both panels. Lightweight sandwich panel roof reduces vertical load of steel frame, matching thin type aluminum honeycomb curtain wall to control overall steel structure investment cost.

Custom consistent surface color and texture for sandwich panel roof and curtain wall to form coordinated facade visual effect. Large factory office area can match aluminum honeycomb curtain wall with high texture, while production workshop uses cost effective EPS or rock wool sandwich panel roof to balance appearance demand and construction budget reasonably.
