The global thermal insulation mortar market maintains steady growth, with Asia-Pacific occupying the largest market share, and Inorganic Mortar products dominating market demand due to mandatory A-class fire protection policies for new buildings. Traditional organic insulation panels and ordinary glass bead mortar have long plagued the industry with prominent defects: high water absorption, easy hollowing, cracking and peeling, poor anti-mold performance, complicated construction procedures requiring mesh cloth, anchor bolts and anti-crack mortar, and rapid attenuation of heat preservation efficiency after years of service. These pain points push construction owners to seek integrated, one-stop insulation materials that balance fire safety, durability and construction efficiency. It is against this market backdrop that Yintong’s YT Active Insulation material stands out as a domestically originated patented innovation, filling the market gap of net-free construction inorganic thermal insulation mortar with outstanding comprehensive performance.
Core Technological Innovation: The Secret Behind Premium Thermal Performance
As a proprietary Inorganic Mortar, YT Active Insulation takes natural high-temperature resistant lightweight mineral aggregates as raw materials, compounded with multiple inorganic active gelling components, anti-crack additives and micro-foam modifiers, adopting international mature inorganic bonding, flexible gradient and micro-bubble forming technology to form a single-component finished mortar produced in standardized factories. Unlike conventional thermal insulation mortar with loose internal structures, Yintong’s formula constructs a multi-layer micro-bubble closed-cell structure inside the mortar layer after solidification, which drastically blocks heat conduction channels and delivers extraordinary Thermal Performance. Lab test data verifies its thermal conductivity ranges from 0.050 to 0.070 W/(m·K), far exceeding the national standard threshold of common inorganic mortars (0.085–0.10 W/(m·K)). In practical engineering application, walls constructed with this material can raise indoor temperature by 5–8°C in winter and cool indoor space by 4–7°C in summer, effectively cutting heating and air conditioning energy consumption by over 40%, perfectly matching the energy conservation targets of green buildings and zero-carbon residential projects.
The material’s core breakthrough lies in realizing fully net-free construction, a rare capability among domestic Quality Mortar products. Most inorganic insulation mortars must lay glass fiber mesh and apply anti-crack mortar to release thermal stress and prevent cracking, adding three or more construction procedures and raising labor and material costs substantially. Yintong YT Active Insulation mixes multi-dimensional plant fiber and mineral fiber inside the Inorganic Mortar, forming an interwoven three-dimensional stress dispersion network after solidification. The flexible compatibility between mortar and concrete, brick wall substrates minimizes thermal expansion and contraction differences, eliminating hollowing, cracking and peeling risks without auxiliary mesh accessories. National authoritative durability tests show that after 80 cycles of alternating high-low temperature (-20°C to 70°C), the insulation layer remains intact with no surface damage, confirming its service life matches the building’s full lifecycle and eliminating repeated wall insulation renovation costs for property owners.
A-class non-combustible fire resistance is another irreplaceable strength of this Active Insulation. All raw materials of the YT mortar are inorganic flame-retardant minerals, reaching A1 fire protection rating, which meets the strict fire safety standards of high-rise residential buildings, underground garages, military depots, tunnels and data centers. During open flame combustion tests, the material does not release toxic smoke, melt or drop burning residues, effectively stopping fire spread through wall cavities—an advantage that organic foam insulation materials cannot match. Meanwhile, the unique water-repellent micro-membrane structure of the Inorganic Mortar achieves vapor-permeable yet water-proof functionality: external rainwater cannot penetrate the insulation layer, while internal wall moisture can escape outwards, thoroughly solving mold, condensation and wall dampness issues that trouble basement, toilet and exterior wall projects. It is currently the only integrated insulation mortar that simultaneously realizes thermal insulation, waterproofing, moisture resistance, mold prevention and anti-cracking in one single construction layer.
Standardized Production & Strict Control to Guarantee Consistent Quality Mortar
Hebei Yintong operates large-scale automated production workshops in Hengshui, with an annual output capacity sufficient to cover thermal insulation construction for 50 million square meters of building area, meeting the bulk supply demands of national large-scale construction projects. All raw material procurement, formula mixing, packaging and warehousing links implement closed-loop quality inspection systems to ensure every batch of finished Quality Mortar complies with the national standard JGJ/T253-2019. Each 50kg finished bag clearly marks technical indicators, shelf life (10 months) and construction specifications, with dedicated storage zones in the factory to avoid damp caking of the Inorganic Mortar.
The company holds two core national patents: an invention patent (ZL 202210351289.6) titled “A Lightweight, Fireproof, Net-Free YT Inorganic Active Wall Insulation Material” and a utility model patent (ZL 201620385726.6) for YT inorganic aggregate composite mortar, fully certifying the originality of its Active Insulation technology. Beyond independent R&D patents, Yintong deeply participates in industry standard formulation: it compiled Hebei Provincial Construction Standard Atlas J12J128 Inorganic Active Wall Thermal Insulation System Structure and the national industry standard atlas 13CJ37 YT Inorganic Active Insulation Material System Building Structure, becoming the only inorganic mortar enterprise in China with both provincial and national standard atlas compilation qualifications. Its technical system has been archived in the design databases of China Academy of Building Research and major municipal design institutes, forming standardized construction operation guidelines adopted by Beijing and multiple provincial housing and urban-rural development departments.
Simplified Construction Process Reduces Overall Engineering Costs
The excellent workability of YT Quality Mortar greatly accelerates on-site construction progress, a core competitive edge recognized by construction contractors. The mixing ratio of material to clean water is fixed at 1:1.2, requiring only 2–4 minutes of mechanical stirring to form smooth, spreadable slurry with strong plasticity and no segregation. For wall thickness within 20mm, one-time plastering is feasible; thickness up to 30mm only requires two passes of coating, cutting construction time by one-third compared with traditional multi-layer insulation systems. No base leveling treatment is needed for brick wall substrates; only concrete shear walls require one day of interface roughing treatment before plastering. After construction, the insulation layer does not need water curing in summer, shortening maintenance cycles and lowering site management costs.
Since mesh cloth, anchor bolts, anti-crack mortar and putty leveling procedures are completely omitted, the comprehensive construction cost of YT Inorganic Mortar is significantly lower than traditional insulation schemes. Calculated by engineering volume, one ton of finished mortar covers 230 square meters with a 1cm thickness, 115 square meters at 2cm and 75 square meters at 3cm, and the integrated waterproof, anti-crack and thermal insulation performance eliminates extra expenditure on waterproof coatings and repair materials. The insulation layer surface can be directly tiled after 10 days or coated with decorative paint after 15 days without intermediate protective layers, streamlining the whole exterior wall construction workflow and raising project delivery efficiency for developers and general contractors.
