Special Thermal Insulation Structure Board For Prefabricated Buildings

Different from the separated structure of traditional external insulation, this product adopts a cast-in-place built-in pull-tab anchoring integrated structure. The insulation board is pre-embedded inside the building wall and completely occluded and poured with the concrete main body through high-density penetrating anti-corrosion pull tabs. The insulation layer, structural layer and protective layer are integrated without hidden dangers of hollowing, layering and falling off. It completely solves the problem of insulation layer falling off under overseas working conditions of typhoons, strong sand wind and large temperature difference, with full wind pressure resistance, earthquake resistance and thermal expansion and contraction resistance. Its service life is synchronized with the building main body, reaching more than 50 years without repeated renovation and repair for life, eliminating exterior wall insulation safety accidents from the source.

Adopting flame-retardant modified high-density insulation core material and matching with an integrated inorganic protective structure, the overall fire flame retardant performance of the product reaches the overseas A1-class non-combustible standard with a fire resistance limit of more than 4 hours. It does not burn, melt, drip or spread smoke in case of open fire, completely eliminating the hidden danger of exterior wall insulation fire. It fully meets the high-grade fire acceptance specifications of schools, hospitals, municipal buildings, indemnificatory housing and commercial complexes in Europe, America, the Middle East, Southeast Asia and other countries, solving the core problem of unqualified fire resistance of traditional insulation boards and blocked project acceptance, with zero acceptance risk, suitable for all overseas public building and residential projects with high fire protection requirements.

Specially modified and upgraded for diverse overseas extreme climates, the product has super performance of high temperature resistance, UV resistance, freeze-thaw resistance, sand wind resistance and damp mildew resistance. It does not age, pulverize or lose insulation performance under continuous high-temperature exposure of 55℃ in the Middle East; no water seepage, mildew or cracking in high humidity environment with typhoons and rainstorms in Southeast Asia; no embrittlement, falling off or unstable insulation in low-temperature freeze-thaw environments in Europe and America. It resists ultra-large day-night temperature difference and alternating seasonal climate corrosion, with stable structure and constant performance in long-term outdoor use, completely solving the industrial pain points of traditional insulation boards such as poor weather resistance, easy damage and short service life.

Traditional exterior wall insulation requires multiple processes such as plastering, leveling, pasting, anchoring, waterproofing and protection, with long construction cycle and high labor costs. The pull-tab integrated insulation board realizes synchronous completion of main body pouring and insulation construction. With factory prefabricated standardized boards, it is directly pre-embedded and poured on site, eliminating more than 80% of traditional external insulation construction procedures and later plastering and leveling. The construction efficiency is increased by more than 3 times, greatly shortening the overall project construction period. Meanwhile, it reduces a large number of labor, material and equipment investment, avoids quality problems caused by manual construction errors, and the comprehensive cost of batch projects is far lower than that of traditional insulation systems, perfectly adapting to the current situation of expensive labor and tight construction period of overseas projects.

Adopting high-density closed-cell insulation core material, the product has ultra-low thermal conductivity and excellent thermal insulation performance, which can effectively block outdoor high and low temperature conduction, with a building energy-saving rate of more than 75%, greatly reducing building air conditioning and heating energy consumption. It fully complies with the construction standards of global low-carbon buildings, green buildings and ultra-low energy consumption passive houses, helping overseas projects obtain green building certification and pass special energy-saving acceptance. It adapts to the current mainstream trend of global building energy-saving upgrading and improves the premium and market competitiveness of projects.

The integrated composite structure is dense and pore-free, matched with pull-tab anchoring and sealing design, which can completely block the capillary water seepage channels of the wall, eliminate rainwater and moisture penetration into the wall, and solve the problems of wall water seepage, alkali return, mildew and steel bar corrosion from the source. Meanwhile, the board has high flexible crack resistance, which can expand and contract slightly with the thermal expansion and contraction of the wall, resist fine cracking of the base layer, keep the wall completely closed for a long time, fully protect the building main structure, and extend the overall service life of the building.
