Curtain Wall Structural & Weatherproof Sealing Solutions
A complete system engineering approach to structural silicone glazing, facade panel movement accommodation, and 25-year watertight building envelopes.
Landmark High-Rise Facades
High wind loads and building sway require coordinated structural silicone (XYT928) and perimeter weatherseal (XYT926) performance across high-rise architectural landmarks.
- Dynamic wind shear resistance up to ±5000 Pa without fatigue failure
- Tested under severe typhoon wind-driven rain and seismic displacement
- Thermal stability range from -50°C freezing to +150°C solar radiation
Structural Bite & Glot Dimensioning
Precision calculation of structural bite (minimum 6 mm) and joint glue thickness based on ASTM C1401 formulas, local wind pressure equations, and glass aspect ratios.
- Bite-to-thickness ratio strictly controlled between 1:1 and 3:1
- Dynamic & dead load analysis ensuring cohesive structural adhesion
- Free CAD blueprint review and calculation reports by CHEMPU senior engineers
Zero Delamination & Stone Staining
Inferior sealants cut with mineral oil bleed plasticizer, chalk, and delaminate within 3–5 years. CHEMPU 100% pure silicone polymers guarantee 25-year structural adhesion without staining natural granite or composite panels.
- Zero white oil / solvent plasticizer adulteration to prevent fluid leaching
- ASTM C1248 non-staining certified for porous stone and anodized metal
- Prevents catastrophic reglazing costs and high-rise hanging scaffolding liability
Standardized Application SOP
A rigorous 5-step site protocol covering the two-cloth solvent cleaning technique, closed-cell PE backer rod insertion, continuous pneumatic gunning, and flush concave tooling for complete joint wet-out.
- Two-cloth solvent degreasing removing atmospheric dust and residual oils
- Backer rod depth gauging to eliminate three-sided joint adhesion restrictions
- On-site peel adhesion testing with field quality inspection logs
