When it comes to winter, the topic of keeping warm and keeping warm is going to be a big fire. But every time we focus our attention on floor heating, air conditioners, and heaters. The most important and fundamental external wall insulation technology is rarely mentioned. You know, if the external wall heat insulation integrated board is selected well, then your home's air-conditioning heating and ah is only useful, otherwise leaking while maintaining the heat, spending thousands of dollars each month is useless. So today we came to talk to you about the external insulation board. 
First, the composition of the external wall insulation board
The external wall heat insulation integrated board is composed of heat insulation layer, inorganic resin board, strong adhesive compound, and finish coating. The fire protection level fully complies with the national fire acceptance standards, and also meets the 10J121 external wall insulation building standards. The external wall heat insulation integrated board combines the decoration and insulation construction into one, saves nearly ten processes, and greatly saves construction time. Compared with the traditional insulation method, the construction period is shortened by 60%, and the construction efficiency is doubled. 
Second, external wall insulation board classification
1. Facing series, including: fluorocarbon metallic paint, fluorocarbon solid paint, real stone paint, imitation stone paint, granite, embossing support, faux brick texture, and texture matching.
2. Insulation material series, including: XPS, EPS, PUR, phenolic board, rock wool board, ultra-thin insulation board. 
Third, the application of the outer wall insulation board
For the new and old concrete, steel structures, solid brick walls, hollow brick walls, pressure brick block walls different, combined with the company to install patents, suitable for all types of wall construction and installation. At the same time, it is also suitable for the transformation of old houses. It has excellent outdoor weatherability, color retention, alkali resistance, water resistance, scrub resistance, crack resistance, temperature change, waterproof, abrasion resistance, collision resistance, and tough and durable paint film, strong adhesion, mildew resistance Excellent results.
Fourth, compared with the traditional external wall insulation system, where is its advantage
1, waterproof, cracking problems. The prefabricated inorganic resin board used in the factory is a decorative surface material and will never produce cracking problems. The use of existing mature curtain wall weathering glue sealant technology can ensure that the joints of the system will not be cracked for more than 20 years.
2, fire prevention issues. The system is fully compatible with the existing fireproof insulation materials, and has excellent fire performance.
3, security issues. The system uses lightweight building materials and weighs only 8-12kg/m2. It is safe and does not increase the weight of the building. The double fastening structure with adhesive and anchorage improves the safety factor of the system; the shedding problem will never occur.
4, durability issues. The surface coating of the system adopts pre-coated fluorocarbon metal plates with strong weather resistance, high self-cleaning, and acid and alkali resistance. At the same time, the system's unique construction system can meet the requirements for the same life span as the building.
5, decorative issues. The surface coating of the system adopts full-mechanical automatic spraying of fluorocarbon metallic paint, inheriting the high decorativeness of the aluminum panel curtain wall and the aluminum-plastic panel curtain wall, so it is more decorative, and the outer panel can also adopt aluminum panels, aluminum-plastic panels, and modeling. Plates and other more advanced special plates, rich texture and creative. And can be installed on a large surface, no color, good appearance. This can overcome the problem of poor decoration of traditional exterior wall insulation systems. 
V. What are the errors that can be avoided in the exterior wall insulation board?
1. Some users think that inorganic insulation material only has good hardness and small aperture is a good product.
2. It is not possible to understand the external wall heat insulation integrated board system. When doing the project, various materials in the external wall insulation and decoration integrated board system do not take into consideration its compatibility and compatibility.
3, the choice of external wall heat insulation one board regardless of quality, only to the price, use cheaper.
4. For some new types of exterior wall thermal insulation materials, the insulation technology cannot be completely denied because of the quality of the factory.
5, can not be selected when the outer wall insulation board as the main insulation material when only relying on the thermal conductivity or the level of water absorption as the evaluation basis.
6, can not be considered on the technical level of closed-hole insulation material thermal conductivity is low, it must be a good insulation material.
7, can not be considered foreign use of polystyrene board for decades, blindly applauded, excluding other insulation system technology.

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Natural Gas Mass Flow Meter, Natural Gas Mass Flowmeter, Natural Gas Coriolis Meter, Natural Gas Coriolis Mass Flow Meter, ATEX, IECEx & CE approved.
First, Sealand meter is certified by Zhejiang Institute of Metrology. To get such certificate, Sealand has to send all models to Zhejiang Institute of Metrology and all models are tested in their calibration lab. The lab is an ISO/IEC 17025:2005 standard lab approved by CNAS (China National Accreditation Service for Conformity Assessment). CNAS is a member of ILAC (International Laboratory Accreditation Cooperation).
Second, Sealand has its own calibration lab, equipped with METTLER TOLEDO scales with accuracy 0.014% and the device extended uncertainty is 0.05%. The lab is also approved by Zhejiang Institute of Metrology. This certificate will stay valid only for one year, Zhejiang Institute of Metrology will send their professor to Sealand every year to check and make sure that the lab is qualified still and then issue new certificate. During the production, each meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
Finally, Sealand also gets ISO, CE, SIL, ATEX & IECEx. Sealand is the only Chinese brand who gets ATEX & IECEx and it is from TUV SUD ( the most authoritative institute for ATEX).
