In the field of building maintenance, exterior wall sealing is the first line of defense to protect the safety of houses. According to the latest report of Grand View Research, the global sealant market will reach US$15.5 billion in 2028, of which silicone sealant leads the market with an average annual growth rate of 5.2%. This article will combine the technical guidelines of the American Institute of Architects (AIA) and industry measured data to prove through 10 core arguments: Silicone sealant has become the best choice for sealing the exterior walls of houses due to its excellent performance.
1. Extreme weather resistance: The ultimate protection against climate change
ASTM C920 standard test shows that high-quality glass glue can maintain elasticity in the range of -50℃ to 200℃, far exceeding the working range of -40℃~120℃ of polyurethane sealants. According to data from the National Oceanic and Atmospheric Administration (NOAA), modern buildings need to withstand more than 50 extreme weather shocks each year, and the weather resistance of glass glue is becoming a key barrier for building protection.
2. Material universality: perfect adaptation to multiple substrates
DOWSIL laboratory research has confirmed that the bonding strength of glass glue to 12 common building materials such as concrete, wood, and metal is above 0.7MPa. Compared with the limited application range of acrylic caulking agent to 3-5 substrates, its wide adaptability greatly reduces the difficulty of construction selection.
3. Dynamic sealing ability: flexible wisdom to deal with micro-deformation of buildings
Simulations by the California Earthquake Research Center show that glass glue can withstand ±50% joint displacement, and its elastic modulus (0.5-1.5MPa) perfectly matches the needs of thermal expansion and contraction of buildings. Compared with the displacement bearing capacity of only ±25% of rigid polyurethane sealants, it has significant advantages.
4. Ultra-long service life: the key to reducing maintenance costs
Statistics from the American Building Maintenance Association (BOMA) show that the average service life of high-quality glass glue is 20-25 years, which is more than three times that of acrylic caulking agent (5-8 years). Taking the maintenance of the exterior wall of the Empire State Building in New York as an example, after switching to uszczelniacz silikonowy, the maintenance interval was extended from 3 years to 15 years.
5. Waterproof barrier: Molecular-level protection against water damage
The ASTM E331 water spray test shows that glass glue can withstand the impact of 200mm rainfall per hour, and its hydrophobic molecular structure makes the water absorption rate less than 0.1% (data source: Dow Corning technical white paper). Compared with the 1.5% water absorption rate of polysulfide sealant, the waterproof performance is improved by 15 times.
6. Energy saving and efficiency improvement: invisible regulator of building energy consumption
The US Department of Energy (DOE) has confirmed that the use of glass glue sealing can reduce building energy consumption by 12-18%. Its low thermal conductivity (0.2W/m·K) effectively blocks the thermal bridge effect, and with the 3M Climate Seal series of products, it can achieve year-round temperature control and energy saving.
7. Anti-ultraviolet protection: chemical armor with long-lasting color
QUV accelerated aging test shows that glass glue containing nano-titanium dioxide (such as Wacker ELASTOSIL®) has an appearance retention rate of more than 95% after 3,000 hours of ultraviolet irradiation (data source: UL laboratory report). Compared with the 60% retention rate of acrylic caulking agent, it significantly extends the building’s aesthetic cycle.
8. Anti-mildew and antibacterial: biological defense line for healthy buildings
EPA-certified antibacterial glass glue has a mold inhibition rate of 99.9%, and its molecular structure destroys the cell membrane of microorganisms. It is particularly suitable for building protection in rainy and humid areas.
9. Construction advantages: dual improvement of efficiency and precision
ISO 11600 standard certified glass glue has a 60-minute surface drying speed and supports low-temperature construction at -10°C. Its self-leveling properties make the joint flatness reach ±0.5mm (data source: Sika construction manual), greatly improving work efficiency.
10. Environmental value: a green choice for sustainable development
The LEED certification system lists low-VOC glass glue (VOC <50g/L) as a bonus item. European REACH regulations data show that the carbon footprint of modern glass glue is 40% lower than that of traditional products, which is in line with the global carbon neutrality trend (data source: EU Building Materials Environmental Protection Annual Report).

Wnioski
In the field of building protection, glass glue has broken through the limitations of traditional caulking agents and built a three-dimensional protection system covering physical protection, chemical stability, and eco-friendliness. From the wind resistance practice in the Florida hurricane belt to the insulation verification in the extremely cold regions of Northern Europe, its performance advantages have been verified globally. It is recommended that owners choose high-quality products that meet the ASTM C920 standard and refer to the AIA construction specifications for professional construction. When architecture meets technology, glass glue is redefining the standard paradigm of exterior wall protection with molecular-level precision protection.
