Wall sandwich panels

Our company produces reliable three-layer metal wall sandwich panels used in the construction of prefabricated buildings and structures for various purposes. Wall sandwich panels of ZMK Pulkovo plant have high thermal and sound insulation characteristics, while they have a low weight and affordable price.

Types of wall sandwich panels

Wall sandwich panels from mineral wool PSM

A insulation is a mineral wool with a density of 100 kg per cubic meter. and more. Mineral wool lamellas are staggered to ensure the strength of the product.

Wall sandwich panels made of expanded polystyrene PSS

For this type of panels, expanded polystyrene with a density of not less than 16 kg per cubic meter is used.

It is also possible to produce three-layer wall panels of the sandwich type with a combined insulation (mineral wool and expanded polystyrene).

The choice of this or that index of thickness of wall sandwich panels is carried out at the stage of designing the object, taking into account the climatic conditions of the terrain in which the construction is planned. Calculations of the heat transfer resistance of walls for different cities of Russia are given on page 10 of the technical catalog.

Fastening of wall sandwich panels

Perhaps both horizontal and vertical arrangement of sandwich panels on the walls of the building. With horizontal placement, the panels are fastened to the columns of the metal frame, which is located vertically, and in the vertical direction to the horizontal crossbars.

Depending on the type of building material to which the external wall sandwich panels are attached, the following types of fasteners are used:

  • concrete / brick - spike-nails;
  • to wooden materials - self-tapping wood D 5,5 - 4,9;
  • to metal surfaces - self-tapping screws for metal D 6.3 - 5.5.

To connect the panels to each other, a Z-lock (Intalock) is used.

Z-lock allows to ensure the strength of the connection of wall sandwich panels with each other. It also reliably protects the connection from moisture, dust, cold.

The price of wall sandwich panels

The price of wall sandwich panels per m2 starts from 750 rubles and depends on the following components:

  1. Type and thickness of the filler. Panels made of expanded polystyrene are slightly cheaper than mineral wool because of the reduced cost of insulation.
  2. Type of coating. Polymer coating also affects the cost of wall sandwich panels per m2 due to differences in its price. So, the most economical is considered to be polyester, and Pural and PVDF have a higher cost. Also, sandwich panels can be made from galvanized steel without applying paint and varnish materials. This option is the most inexpensive.
  3. Standard colors from the RAL catalog are more economical compared to rare and less common colors.
  4. The volume of the order. ZMK Pulkovo has special prices for three-layer wall sandwich panels with an order volume from 201 to 1000 sq.m., as well as over 1000 sq.m.
  5. The thickness of the metal.
