What are the advantages of insulated sandwich panel?

MAY. 23, 2020

The insulated sandwich panel house has the advantages of light weight, high strength, heat preservation and insulation, beautiful and economic use, etc. it is convenient to build high-grade construction equipment integrated with decoration. The insulation sandwich panel movable building construction cleaning is widely used in the roof plus floor, air purification room, cold storage, shop, kiosk, large-span workshop, warehouse, office building, villa and so on.


Insulation sandwich panel has three advantages


  1. Thermal insulation: common thermal insulation materials of color steel plate composite board are rock wool, glass fiber cotton, polystyrene, polyurethane, etc., with low thermal conductivity, and then the activity room has outstanding thermal insulation personal role. With high-strength color steel plate as the base material and the most advanced description and rolling forming, the insulation sandwich panel movable room has excellent layout characteristics.


  1. Convenient device: The insulation sandwich panel modular room has light self-weight, splicing device and the characteristics of being able to be cut at will, which can save the construction period. The panel materials and thermal insulation materials of the fire-resistant color steel plate sandwich panel are non-combustible materials, which can completely satisfy the fire standard requirements of the activity room.


  1. Durable: The shelf life of the insulation sandwich panel treated by special coating is 10 to 15 years. In the future, the anti-corrosion coating will be sprayed every 10 years, and the service life of the plate in the activity room can reach more than 35 years. Beautiful, profiled color steel plate clear lines up to dozens of colors, can cooperate with any individual activity room needs.

Insulation sandwich panel can prevent fire from six aspects


First: use rock wool with good fire resistance as core material, which is the way to cure the root cause


Second: in the process of construction, the core material shall be kept away from open flame operations such as electric welding and gas welding


Third: in the process of use, some heat sources and fire sources shall not be close to the steel plate, and a certain distance shall be kept. If the kitchen is to be set in the color steel room, a temperature insulation layer shall be provided, and the wall shall be equipped with a fireproof rock wool insulation layer


Fourth: wires and cables are better not to pass through the core material. If it is necessary to pass through, protective sleeves, sockets and switch boxes shall be made of metal galvanized boxes and surface mounted methods shall be adopted


Fifth: simple fire-fighting equipment shall be equipped indoors and outdoors, and fire alarm shall be installed if conditions permit, so as to facilitate rapid evacuation of personnel


Sixth: a safe distance of at least 6 meters shall be kept between the color steel plate rooms. Although the filling material of the color steel plate room without strict fire-retardant treatment is flammable, it will not self ignite. Strict, scientific and effective management can keep the fire away from the filling material of the color steel plate room, which is one of the important ways to prevent the sandwich panel house from fire.

Six characteristics of insulation sandwich panel


Sandwich panel refers to color coated steel plate sandwich panel. Color coated steel plate is a kind of steel plate with organic coating. Color steel sheet is divided into single plate, color steel composite plate, floor bearing plate, etc. it is widely used in large-scale public buildings, public workshops, movable plank houses, and the walls and roofs of integrated houses.


Six characteristics of foam sandwich panels:


1. Light weight: 10-14kg / m2, equivalent to 1 / 30 of brick wall


2. Thermal insulation: thermal conductivity of core material: ‎λ < = 0.041w/mk


3. High strength: it can be used for bearing, bending and compression resistance of ceiling enclosure plate. Generally, the house does not use beam and column


4. Bright color: no surface decoration is required, and the retention period of anticorrosive coating of color galvanized steel plate is 10-15 years.


5. Flexible and fast installation: the construction period can be shortened by more than 40%


6. Oxygen index: (OI) 32.0

The insulation modular house has the advantages of light weight, high strength, heat preservation, heat insulation, beauty and durability. It is an advanced building and decoration integrated


Quick installation of buildings

It is widely used in large-span factory buildings, warehouses, office buildings, villas, roof plus floors, air purification rooms, cold storage shops, kiosks and temporary rooms. The weight of the light foam color steel sandwich panel is less than 14KG square meters, so as to reduce the structural load and reduce the cost of the movable room structure.


Easy to install

The characteristics of light weight, splicing installation and free cutting of color steel plate mobile room decide that the installation of the mobile room is simple and convenient, which can greatly improve the efficiency and save the construction period. The surface material and thermal insulation material of fire-resistant color steel plate sandwich board are non-combustible materials, which can fully meet the requirements of fire prevention specifications of mobile room.


A variety of studies have shown that the shelf life of sandwich panel treated by special coating is 10-15 years, and after spraying anticorrosive coating every 10 years, the service life of movable house plate can reach more than 35 years.


Beautiful profiled color steel plate with clear lines in dozens of colors can meet the needs of any style of mobile buildings and achieve satisfactory results.


Thermal insulation

The common thermal insulation materials of the insulation sandwich panel composite board are rock wool, glass fiber cotton, polystyrene (EPS), polyurethane, etc., with low thermal conductivity, so the movable room has good thermal insulation effect. The high-strength color steel plate is based on high-strength steel plate (tensile strength 5600kg / cm) and the most advanced design and roll forming, so the color steel plate mobile room has excellent structural characteristics.

Specification and performance of metal skin sandwich panel:


1. The metal skin sandwich panel, often adopts the slotted plug-in type, which has the advantages of convenient installation, time-saving, material saving, good flatness, high strength, etc. it is suitable for ceiling and partition system.


2. Thickness (mm): 50-250;


3. Length (mm): due to continuous forming production, the plate length can be determined according to user needs:


4. Width (mm): 1150 (1200)


5. Properties of core material: A. bulk density of polystyrene: 215kg / m3, thermal conductivity coefficient s0.036w/m.k, maximum service temperature: about 100oC
