What is the difficulty of calculating the consumption of sandwich panels

All kinds of structures are being built from sandwich panels, from small stalls to production facilities. Before embarking on the construction and procurement of materials, it is important to correctly calculate the number of sandwich panels. Even experienced builders sometimes make mistakes, and there is a lot of excess material left, or vice versa you have to buy it.

When mounting walls of this material, it must be taken into account that when using the groove-comb connection, the panels are adjusted in length without changing the fixed width that is laid down by the manufacturer. This means that you should not change the width yourself. In this case, the structural properties of the joints are violated, and the seam is not tight enough, sooner or later it begins to freeze. In addition, it gives an unpleasant visual effect. Such a joint cannot be masked, it will be especially noticeable if panels of different colors are used. The defining moment in calculating the consumption of sandwich panels should be the working width, which is laid down by the manufacturer.

If it is necessary to calculate the amount of material for the reconstruction of the building, then the volume needs to be selected, I focus on the available room parameters. It is important not to forget that on the runs and crossbars the sandwich panels will dock in length. There are no other options, because the ends of the panels must be fixed in any case. If this material is used for roof installation, they need to be laid out from top to bottom, that is, they will be laid along the distance from the ridge to the parapet. At the same time, the junction along the length will not be of great importance.

When there is a horizontal section of the wall sandwich panels, the length is determined 2 cm shorter than the distance between the central axes of two adjacent columns. The length of the panels during vertical cutting is also determined by 2 cm less than the distance between the upper and lower crossbars of the wall half-timbered houses. The designated distance is necessary to provide thermal insulation for joints that are closed with special platbands. Joints in corners are usually made out of typical nodes, often this is done using special interior and exterior parts of thin steel sheets matching color using insulation between them. The insulation material must be resistant to the formation of fungus and be flexible enough, most often it is mineral wool.
