Certifications & Honors

DERCHI products are engineered and tested to comply with the most demanding global building codes. Our structural glass and profile solutions meet international standards across multiple continents.

Our frameless glass entry door products carry certifications including Hurricane Certification, CE (EU), NFRC (USA), AS2047 (Australia), CSA (Canada), Energy Star, and ISO 9001. This ensures compliance with structural integrity, thermal transmission, and windload requirements in high-velocity hurricane zones (HVHZ).

1. Structural Glass Integrity and Safety

Frameless glass entry doors rely entirely on the glass pane itself for structural stability. At DERCHI, we utilize heavy-duty tempered safety glass (fully toughened) or laminated glass options. Tempered glass is up to five times stronger than standard float glass, fracturing into small, harmless granular pieces upon impact. Laminated glass, containing a polyvinyl butyral (PVB) or SentryGlas Plus (SGP) interlayer, maintains its barrier integrity even when shattered, providing excellent protection against forced entry and high-velocity storms.

2. Heavy-Duty Pivot Hardware Engineering

Because frameless doors lack traditional side frames, weight distribution is handled via top and bottom pivot hinges. Our hydraulic self-closing pivot hinges support door weights up to 350kg. They feature adjustable closing speeds, latching speeds, and hold-open angles (typically at 90 degrees). The hardware is manufactured from marine-grade 316 stainless steel to ensure rust-resistance and long-term durability in coastal locations.

3. Customization & Aesthetic Finishes

We offer extensive aesthetic options to harmonize with different architectural styles. Glass surfaces can be customized with acid-etched frosted patterns, sandblasted textures, tinted coatings (bronze, grey, or blue), or ultra-clear low-iron glass for maximum light transmission. Handles are available in varying lengths—from minimalist patch locks to full-length ladder pull bars integrated with biometric smart lock systems.

4. Weather-Sealing & Thermal Control

A common challenge for frameless doors is air infiltration. DERCHI solves this by incorporating high-density silicone weather strips, sweep profiles, and drop-down seal mechanisms. For cold climates, we supply thermal break aluminum sub-frames and double-glazed low-E glass options, ensuring the door system meets modern energy efficiency regulations without compromising the minimalist look.
