Innovative approaches to the construction of various types of hangars make it possible to adapt buildings to any climate conditions. The structures are highly durable and reliable. Additional treatment ensures corrosion resistance.
What is hangar insulation for?
A hangar is a functional structure used in various fields of activity. The choice of model depends on consumer needs. When insulating buildings, the type of installation technology is taken into account.
High-quality insulation of the hangar makes it possible to expand the scope of the building. It can be used as a premises for a sports complex or a production workshop.
Thermal insulation provides sound insulation, reduces heat loss. Multi-layer insulation provides the building with strength and rigidity, serves as protection against rust and condensation.
Types and features of hangars
Hangars are erected on a frame basis and without it. Each model has its own positive and negative characteristics. Installation technology, operation and maintenance of different structures have a lot in common.
Wireframe
Models are buildings with a metal frame. The hangar is installed on a foundation and covered with cladding. The frame is subject to assembly and disassembly. Structural elements are fastened by means of bolts. The functionality and economy of the building depend on the form.
The basis of the frame is made up of channels, I-beams and pipes, as well as other metal components. The structure is treated with a primer of any color. Metal hangars are cold and warm. The walls of cold models cannot be insulated.
Frameless
Frameless models are built directly on the construction site using special mobile devices. The construction implies the profiling and corrugation of coiled steel to give it the required radius. The arched element is connected into blocks using a flanging machine. Then they are lifted by a crane and installed on the finished foundation. The elements of the building are fastened together by means of spot welding and bolts.
Advantages and disadvantages
Structures based on a metal frame are distinguished by their strength. The service life, with proper use and prevention, is twice as long as that of frameless models.
The technical advantage is explained by:
- the presence of a strong foundation;
- installation of durable load-bearing elements;
- high level of hangar stability.
The disadvantages of the construction include the duration of the construction of the foundation. It can usually take up to two weeks for the base to be poured in good weather conditions. With constant rains, it will take a month. The frame is assembled after the concrete has completely hardened.
The main advantages of frameless construction include water impermeability and tightness of folded fasteners, which reduces operating costs.
The disadvantages include:
- a decrease in the usable hangar area due to giving the building an arched shape;
- limitation of the overall dimensions of the building;
- low altitude.
Frameless models are installed at one time, since they cannot be disassembled.In the event of a breakdown, the building cannot be repaired. It is possible to replace only part of the arches from the edge. Items in the middle are not restored. Structural fasteners also have disadvantages.
Equipment for making frameless models should be located on the construction site, although some firms offer a service for installing a finished structure.
Hangar insulation options
An important element of the hangar is its insulation. Various materials are used to ensure the optimum temperature.
Sheathing with corrugated board and galvanizing is carried out from the outside and from the inside. Internal insulation reduces the building area, but such insulation is highly effective.
External installation of panels has the main function and serves as protection against heating and hypothermia. This increases the service life.
As heat insulators, sandwich panels, ecowool, polyurethane foam (PPU), foamed polyethylene or foam foil, mineral wool are usually used.
Sandwich panels
The material contains three layers. Two of them are made of galvanized metal sheet. The third serves as insulation. Often mineral wool acts in its role. There are wall and roofing elements on the market that differ in color.
Insulation by means of sandwich panels is an advantageous solution for the construction of a hangar with straight walls. The panels act not only as a heat insulator. They serve as a fence, protection of the building. The elements are distinguished by their aesthetic appeal.
Insulation of walls with sandwich panels is characterized by low thermal conductivity and high level of strength. The panels are lightweight, which makes it possible to pour the foundation of a shallow depth.
Mineral wool
Mineral wool is used as a separate material. It is assembled in layers. It has a density of 130-140 kg / m. Insulation does not change the quality and shape with changes in temperature and can be used when it is too high. Mineral wool is resistant to chemicals and weather conditions, and protects the metal frame from rusting.
The material is used for any model of construction. It can also be used in the construction of a frameless structure.
The main disadvantage is the lack of resistance to moisture. To eliminate water absorption, mineral wool is covered with a special membrane film. The same rules are followed when carrying out work inside the building.
The material is notable for its affordable cost, quick installation and ease of use. The price of mineral wool depends on the thickness, density and grade of the substance.
Ecowool
Ecowool is a cellulose insulation. It is not rotting, flammable or moldy. It is an environmentally friendly material.
Ecowool can be used to insulate hangars in which food products are stored. Installation can be carried out both outside and inside. Carried out by wet or dry method. In the latter method, cellulose fibers are blown between two surfaces. In the wet method, the fibers are wetted with water, to which glue is added. The product is applied by spraying. A dense coating without seams and an affordable cost makes this type of insulation a priority.
Polyurethane foam
Foam is applied to the hangar surface by means of a special apparatus, in which the components of the insulation material are mixed. The finished mixture enters the sprayer under high pressure. On the surface, polyurethane reacts with air to form foam.The capture of air molecules increases the volume by 80-100 times. The material solves many problems due to its application method and technical characteristics. This method of insulation is often used by developers, since the installation is quick and easy.
Polyurethane foam is the ideal way to insulate a hangar in the form of an arch. It has a high level of adhesion to metal, applicable to any form of construction.
The material provides a smooth surface without cracks and gaps. Does not require lengthy and expensive preparation for application. Insulation of polyurethane foam hangars allows you to control the thickness of the insulation, which saves money.
Polyurethane foam has excellent adhesion to the surface of the walls, even with existing irregularities, bends or complex structural shapes. This explains the use of the substance for arched frameless structures and polygonal structures.
The operational life of polyurethane foam insulation is 30 years. In the absence of bad weather conditions, the duration of use increases to 50 years. The hardened substance does not put additional stress on the foundation. The cost of polyurethane foam depends on the thickness of the layer and the size of the hangar.
Foamed polyethylene or foamed penofol
The base is polyethylene foam covered with reflective foil. Thermal insulation with material is an innovative approach to thermal insulation. The thickness of the penofol is no more than 1 cm, the foil layer is 20 microns. For cold regions, a material with a thickness of 40 mm is produced.
The disadvantages of the material include:
- low stiffness;
- conductivity of electricity;
- high level of adhesion.
The main advantage is reflection. Thanks to this property, heat is not retained in the room, as it happens when installing other heaters. The method provides coolness in summer and warmth in winter. Also, the advantage is low weight, which ensures ease of installation and transportation. Penofol does not create a large load on the structure.
Strength and positive performance characteristics made penofol popular. The material does not break, which makes it possible to insulate hangars a second time.
