Due to the wide variety of foam glass boards available on the market, users may face some confusion when selecting products. Therefore, as a manufacturer of foam glass, Henan Huitong provides an explanation of the characteristics of its products to help everyone select better foam glass.When selecting foam glass, consider the following aspects:1. Good foam glass should have a low thermal conductivity coefficient. The thermal conductivity coefficient is an important reference factor for determining the quality of foam glass; the lower the coefficient, the less energy will be transmitted through the material, resulting in better insulation performance.2. It should have good sound absorption properties, which depend mainly on the density per unit area; the higher the density, the better the sound absorption. 3. Good foam glass should have low hygroscopicity; as most insulation materials lose their insulating properties after absorbing water, since water has a high thermal conductivity coefficient. 4. Good glass boards must possess high strength to support their own weight. Thus, when purchasing foam glass boards, refer to the above aspects to choose ** quality products. Henan Huitong specializes in the production and sale of insulation materials, providing higher cost performance.

Our booth number is 1039. We welcome people from all sectors to visit and guide us.

Recently, some authoritative experts in China have proposed establishing guidelines for foam glass insulation boards, primarily because, in some regions, there has been chaos in the market for foam glass insulation boards. Experts analyze that some building fires are not only related to exterior insulation materials but also intricately linked to construction management, material management, safety management, and construction procedures.Previously, relevant departments had made decisions regarding new fireproof foam glass insulation boards. However, many manufacturers of foam glass insulation boards were affected, facing obstacles in their sales. Due to the lack of unified standards for some new types of external insulation materials, companies created their own enterprise standards, but the time for standard filing is generally prolonged, which can hinder production.Foam glass is used as wall insulation material, replacing red bricks, reducing wall thickness, and saving energy, which indirectly expands the usable area while decreasing the self-weight of the building. When installed, regular cement mortar or polymer cement mortar is used for adhesion, providing strong bonding. If used as an external wall coating, simply apply a layer of cement mortar over the foam glass layer for leveling. If using colored foam glass, it can be cut into specific shapes, directly bonded with polymer cement mortar.Foam glass insulation bricks can be adhered to walls or ceilings using adhesives, leveled, and then painted with decorative coatings. Wood wool boards can also serve as insulation layers. Wood wool boards act as sound-absorbing materials and are often seen on theater and cinema walls. However, this material is relatively expensive and is suitable when rooms require both insulation and sound absorption. Alternatively, battens can be installed on the wall, filled with insulation materials such as mineral wool, and then covered with gypsum boards. This method requires tight coverage to prevent dust leakage.

Foam glass is a lightweight, high-strength insulation material known for its excellent thermal insulation, acoustic absorption, moisture resistance, and fire resistance. Due to the rapid development of foam insulation materials, many construction materials in various industries rely on foam glass insulation boards. With its superior properties, foam glass insulation boards play a crucial role in the construction industry.The applications of foam glass in energy conservation in buildings mainly include:1. Roof insulation. The insulation structure forms for foam glass insulation boards used on roofs are primarily upright, inverted, and sloped. Inverted roofs can be used for planting vegetation or storing items; they can also achieve various effects on roof terraces. Foam glass easily pairs with other traditional building materials, is easy to construct, waterproof, non-combustible, and has excellent insulation performance.2. External wall insulation. When foam glass is used on external walls, the thickness of the wall is significantly reduced, greatly reducing the weight of the building structure and thus expanding the indoor area. During construction, a special adhesive is used to attach the foam glass to the outer surface of the wall; then, the surface of the foam glass insulation board can be decorated as desired.The external wall insulation technology uses a special adhesive to securely fix the foam glass to the base wall, with a crack-resistant mortar applied for surface treatment. The outer layer can be finished with preferred materials and decorations, making it not only sturdy but also fire-resistant, waterproof, and aesthetically pleasing. The higher the fire rating requirement, the more the unique charm of foam glass insulation boards is highlighted.

After preliminary preparations in 2013, in 2014 our company introduced production technology and equipment from Korea. With the cooperation and efforts of various parties, HT thermosetting modified polystyrene boards (True Gold Boards) have officially entered production, with production equipment adjusted to normal and product quality stable. On May 10, relevant leaders and staff from the Henan Provincial Academy of Building Science visited our production site accompanied by our company leaders to inspect and guide our operations, conducting sampling checks of the new product HT thermosetting modified polystyrene boards (True Gold Boards) and further assessing the corresponding performance indicators. The inspection team unanimously recognized our new product.       Henan Province and nearby regions are among the areas where construction insulation material panel products are widely used. We will provide high-quality products and better services to serve our customers, and producing green, energy-saving, and environmentally friendly products has always been the benchmark of our company’s efforts. As of now, our newly inspected product HT thermosetting modified polystyrene boards (True Gold Boards) has been tested by the Henan Provincial Academy of Building Science, and all product indicators meet national standard requirements, and our product quality can compete with that of Korean companies.

Wall insulation materials have become very popular in the construction industry today. As the variety of cryogenic materials increases, the requirements for these materials have also risen. The popularity of foam glass insulation boards composed of foam glass in wall insulation materials is due to meeting the following three conditions.In building insulation materials, the so-called non-combustible materials refer to non-combustible materials, among which inorganic active wall heat-insulating materials are new types of non-combustible materials. These materials are used as substitutes for red bricks in construction insulation, reducing wall thickness and saving energy, indirectly expanding usable area and reducing the self-weight of structures. They serve as both insulation materials and cryogenic materials. However, currently, the major construction external insulation materials on the market in China are mainly organic materials, which can only reach B1 grade even with the addition of flame retardants. Strict enforcement of fire regulations would mean a complete reshuffle or even elimination of the insulation material industry in China. Therefore, for some time, there has been a strong voice within the industry calling for the revision of external wall insulation product standards.According to the meeting on developing green, safe, and environmentally friendly building insulation materials and industry access requirements, it was proposed that new types of building exterior insulation materials should be safe and environmentally friendly, meeting the following three conditions:First, the material production process should be safe and environmentally friendly, causing no direct harm to safety, health, or the environment, nor leaving hidden dangers for accidents;Second, the intrinsic safety of the material should be high; during storage, transportation, operation, use, and disposal, it should not easily cause safety hazards or secondary disasters;Third, the material's entire lifecycle consumption, energy usage, waste emissions and treatment, impact on the ecological environment and climate change, as well as overall cost should show further improvement compared to traditional materials.
