What is a sandwich construction and what it eats?

In this article I will tell you what sandwich panelsWhat are the main types of sandwich panelsTheir arrangement and composition, as well as briefly Let us examine the scope of such panels.

The main types of sandwich panels:

1. ALUMINUM
«sandwich"It is intended to protect the product from the environment, and to maintain a specific indoor air required parameters. «sandwich"Represents a two layer aluminum sheet with a special coating, are filled with filler. In most cases, as an outer protective material serves polyester. This material is sufficiently resistant to the aggressive environment. It is resistant to UV light and is totally inert to temperature changes and humidity. The thickness of the outer coating of such panels is about 25 microns. Depending on where you will use these panels filler "sandwich" is an mineral wool based on basalt, and polyurethane foam. These constructions with aluminum coating are highly resistant to thermal stress, corrosion.

2. STAINLESS STEEL

SObekty requiring a fairly high degree of protection from moisture or steam, which cause corrosion, require an optimal decision for such objects.
Here are some distinctive features: ease of installation, durability, aesthetic appearance, the combination of different materials such as wood, stone and glass. stainless steel - a fusion of gland, chromium or nickel. Chromium just adds to it corrosion resistance, Whereby a metal surface protective film is formed. The ability to effectively combat corrosion It depends on the percentage of chromium in the composition and, of course, on the other alloying elements.

3. polyurethane foam

PIR. Sandwich panels pnopoliuretana or another name - panel PIR - a panel with insulation, three-layer, the base material is - foams. The main properties of this material: high fire resistance, small enough heat conductivity. polyisocyanurate - beautiful heat-insulating materialSuitable for construction wall and roof panels.
PUR - a three-layer sandwich panels, Consisting of polyurethane foam. have significant insulating properties. Fairly well-proven in harsh environments. It has high strength, good environmental performance and long service life.

Wall sandwich panels - it is quite light, with three-layer insulation of polyurethane foam or flame-resistant polyisocyanurate. These panels can be used as walling of buildings of any appointments. In this type of panels of high environmental friendliness, good enough service life, excellent thermal insulation and high strength. These panels can be used, and corrosive environments.

Roof sandwich panels - This sandwich panels with a heater from polyurethane foam or foams. The main feature of these panels from the wall is four stiffeners. Due to these edges, these panels can carry significant Snow and wind loads. apply these panel can roof with a minimum slope of at least 5-7 degrees.
