Procurement FAQ

Frequently Asked Questions for Aluminum Sliding Doors

What are the primary advantages of Vancoor Entrance System Co., Ltd. Aluminum Sliding Doors?

Vancoor Entrance System Co., Ltd. aluminum sliding doors offer panoramic views, abundant natural light, thermal insulation, acoustic noise reduction up to STC 40dB, and multi-point security hardware. Built with high-strength 6063-T5 aluminum extrusions, our sliding doors provide exceptional structural longevity and minimal maintenance requirements.

How do thermal break profiles improve sliding door energy performance?

Our thermal break aluminum sliding doors utilize high-grade PA66 polyamide insulation strips placed between interior and exterior aluminum profiles. This barrier interrupts conductive heat flow, preventing unwanted heat gain during summer and thermal loss during winter, significantly reducing building energy expenses.

Can sliding doors be customized for large architectural openings and corner designs?

Yes. All sliding door units are engineered to order. We offer heavy-duty Lift & Slide systems, slim-line sliding profiles, multi-panel pocket sliding doors that hide within wall cavities, and 90-degree postless corner sliding systems for expansive architectural openings.

How are sliding door orders packed to prevent damage during sea shipment?

Every door panel and frame unit undergoes protective surface film application, thick foam corner wrapping, multi-layer bubble wrap packing, and fully enclosed plywood crate packaging to ensure transit protection during container shipping.
