Pay attention to the waterproof design of the roof panel.
Jul 14, 2018

The waterproof layer of aerated concrete roof panels is not only the waterproofing requirement of buildings, but also an important measure to protect aerated concrete roofing panels. The coiling materials are still commonly used at home and abroad. Since the board is narrow and the side of the board is butt jointed, the overall rigidity is poor. Therefore, if the linoleum is directly laid on the roof panel, the following points should be noted in the design:

1. The waterproof layer of aerated concrete roofing panel should have better overall rigidity in addition to its own waterproof performance. The overall stiffness of the board should be well connected with the main structure, mainly Strengthen the joint between the side seams. If the gap is small and the general cement mortar is used for filling, the metal sheet subjected to anti-rust treatment should be nailed between the joints, or the mortar should be bonded.

2. In the flat roof, generally no slope is found on the upper part of the roof panel and the slope is determined by the structure. Only when the slope of the support is uniform and flat, the flatness of the board surface can be ensured, and the linoleum can be laid.

3. Before the aerated concrete roof panel is made of linoleum, there is generally no gas barrier layer in the upper part. The function of the gas barrier on the reinforced concrete roof is to prevent the moisture in the room from penetrating into the insulation through the reinforced concrete roof panel and affecting the insulation effect. However, the aerated concrete roof panel itself is the insulation material, so it is separated in the upper part. The gas layer has lost its meaning.
