The use of color steel sandwich panels on the exterior wall improves the wetness of the wall

- May 28, 2019-

Under normal circumstances, the inner insulation shall be provided with a vapor barrier layer, and the outer wall shall be a color steel sandwich panel.

Since the main structural material with high vapor permeability is inside the thermal insulation layer, as long as the color steel sandwich panel is properly selected, the interior of the wall is generally Condensation does not occur, so there is no need to install a vapor barrier.

At the same time, after the external thermal insulation measures are taken, the temperature of the entire wall of the structural layer is increased, and the temperature content thereof is lowered, thereby further improving the thermal insulation performance of the wall.
