1. How to choose external wall insulation board?
1. When purchasing external wall insulation board, check the product appearance. It is required that the damage is small, the color is consistent and the size is accurate (the tolerance of length and width is 4mm and the tolerance of thickness is 2mm).
2. When purchasing exterior wall insulation board, measure the product density. Choose a product, weigh it, measure its volume, and you can calculate the density. On the premise of meeting the strength requirements, the smaller the density, the better.
3. When purchasing external wall insulation board, simply measure the strength. In addition, the strength requirement of thermal insulation products is mainly to meet the needs of handling, but it is generally not high, and it is110-1/20 of the strength of red bricks, but it can't be broken and pinched. According to the standard requirements, the compressive strength is generally above 0 and 5MPa, that is, the general product should be able to withstand a person standing on it gently (the product area is larger than the foot area.
4. When purchasing exterior wall insulation board, combustion performance: Combustion performance refers to all physical and chemical changes that occur when building materials burn or encounter fire, but this performance is measured by the characteristics of flammability on the surface of materials, flame spread, heating, smoking, carbonization, weightlessness and generation of toxic products.
5. When purchasing the external wall insulation board, the thermal load contraction temperature: the thermal load contraction temperature is used to indicate the damp-heat stability of the insulation material.
2. What are the manufacturers of external wall insulation board?
1. Jiangsu EMI Energy-saving Building Materials Co., Ltd. is an energy-saving building materials enterprise specializing in R&D, production and sales of imitation stone paint and imitation slate. In 200 1 year, EMI creatively realized the EMI characteristic putty product system matching with coating products from the initial research and development of building putty products. In 2006, the stone-like paint products based on EMI putty further met the needs of customers and the market.
2. Beijing Changheyu Construction Engineering Co., Ltd. is an extruded board, floor heating extruded board, polystyrene board, bonding mortar, anti-crack mortar, grid cloth, insulation nail, external wall insulation construction, extruded board, floor heating extruded board, polystyrene board, bonding mortar, anti-crack mortar, grid cloth, insulation nail, external wall insulation construction, mortar cement, agent extruded board, aluminum insulation nail, alkali resistance.
3. Shandong Baikal New Building Materials Co., Ltd. is a company specializing in the production and processing of metal carved thermal insulation external wall panels and other products. Founded on 20 12, it is a building material enterprise for thermal insulation and decoration of external walls in China. The company has been committed to building materials products with high quality, high performance and technological innovation. Looking forward to the development trend of the international building materials market and the development demand of the construction industry, our company independently developed and produced an energy-saving and environmental protection product representing the advanced level of exterior wall building materials, and obtained the utility model patent certificate issued by the State Patent Office.
