LANCE
Rolansini
When it comes to exterior doors that blend durability, safety, and efficiency, the LANCE Hurricane Proof Dual Glazed Glass Heavy Duty Lift Sliding Door stands out as a game-changer. Crafted by Rolansini, a leading manufacturer in China, this door is engineered to meet the most demanding needs of modern architecture—from withstanding extreme weather to enhancing energy efficiency and daily usability. Whether for patios, gardens, villas, or sunrooms, it combines robust construction with smart design, making it a top choice for both residential and commercial projects.
The LANCE lift sliding door is built around core strengths that address real-world challenges. Its energy efficiency is a standout feature, thanks to advanced thermal insulation technology that minimizes heat transfer, reducing reliance on heating or cooling systems. For homeowners and businesses prioritizing security, the door offers enhanced protection: when fully closed, its design prevents tampering from the bottom, while interlocking mechanisms add an extra layer of defense against intruders.
Durability is another hallmark. Constructed with high-grade materials, it boasts a long service life, even in harsh environments. The easy-operation design ensures smooth functionality, with a lift-slide mechanism that makes opening and closing effortless, even for large panels. Plus, its large-size design allows for expansive openings, creating seamless transitions between indoor and outdoor spaces while maximizing natural light.

Designed to thrive in storm-prone areas, the LANCE door features a hurricane-resistant structure that sets new standards. It uses 6063-T5 aerospace-grade aluminum and PA66GF25 reinforced nylon strips, enabling it to withstand 3,500Pa wind pressure (meeting CNS 3092 Class 12). Interlocking EPDM gaskets deliver IP68 watertight sealing, while staggered drainage channels prevent 98% of water ingress during heavy storms. Diagonal reinforcement bars further boost structural integrity, allowing the door to resist winds up to 150km/h—a critical feature for coastal or high-wind regions.
At the heart of its smooth operation is the German Sobinco vertical-lock system, which creates 12-point compression sealing (EN 12207 Class 4). This reduces air leakage to ≤0.5m³/m·h, enhancing both energy efficiency and sound insulation. The roller system, tested to handle over 100,000 cycles, supports up to 300kg per panel, lowering door panels onto precision-ground tracks for whisper-quiet movement. For added convenience, optional soft-close buffers extend hardware lifespan by 60%, ensuring long-term reliability.
Energy efficiency is elevated by a thermal break design using German TechNoForm’s PA66GF25 thermal barrier, which has a conductivity of just 0.3W/m·K. This barrier separates interior and exterior profiles, achieving a U-value of ≤2.0 W/m²K—ideal for maintaining consistent indoor temperatures. The dual-chamber frame, paired with a 27A argon-filled glass cavity, reduces heat transfer by 40%, cutting energy costs year-round.
The door's 27Ar acoustic insulation glass option takes comfort to the next level. A laminated configuration (6mm+PVB+6mm+27A+6mm) achieves an STC 38 rating, blocking 90% of urban noise in the 500-2000Hz range—perfect for homes near busy streets or commercial areas. Argon-filled chambers and warm-edge spacers minimize resonance, while PVB interlayers dampen vibrations by 30dB. For light management, optional Low-E coating maintains 85% visible light transmittance (VLT) while rejecting over 99% of UV rays, protecting interiors from sun damage.
From its hurricane-resistant build to its energy-saving features, the LANCE Hurricane Proof Dual Glazed Glass Heavy Duty Lift Sliding Door is more than a door—it’s a long-term investment in safety, comfort, and style. Backed by a 10-year warranty and compliance with global standards, it’s engineered to perform where other doors fall short. Explore how it can transform your space today.
