Double-Glazed Sliding Doors
Double-glazed sliding doors are glass sliding doors with two panes of glass separated by an insulating gas layer. This structure reduces heat transfer compared to a single pane of glass, making them a genuinely energy-efficient choice for commercial entrances.

Our Double-Glazed Sliding Doors for Businesses
At Dasco Entrance Technology, our range of double-glazed sliding doors is built for daily use in busy commercial settings. Each system is durable, secure and low maintenance. With design, manufacturing, engineering, and installation all handled in-house, you deal with one team throughout, with full accountability at every stage.
Our entrance systems support building efficiency, security and everyday convenience for staff, customers and visitors. We’re double-glazed sliding door suppliers for:
We also supply industrial double-glazed sliding doors engineered for warehouses and workshops. Built to withstand high-traffic industrial environments, these units help reduce heat loss, control energy costs, and maintain consistent internal temperatures without compromising on performance.
How Double-Glazed Sliding Entrance Systems Work
Sliding doors consist of large glass panes set within panels that run along a track and open by moving sideways. Our automatic sliding doors run smoothly along fixed tracks with running carriages, supporting effortless operation and quiet daily use. Each system is sensor-activated, giving staff and visitors easy access without touching the frame.
The large glass areas of sliding doors maximise natural light, making them ideal for showrooms, reception areas and retail entrances. Unlike swing doors, they don’t need an arc of open floor space to operate. This makes them a practical choice where floor space near the entrance is limited.
The frame material of sliding doors affects durability, aesthetics and maintenance. Our high-quality aluminium frames offer enhanced strength, accommodating larger glass areas for optimal sightlines. Other frame materials, such as uPVC and timber, are common in the wider market. Both generally need more maintenance to prevent weathering over time.
Proper installation is critical to the performance of sliding door systems. Our engineers survey your opening before manufacture, so the finished system fits and operates correctly from day one.
Energy Efficient Double-Glazed Sliding Doors
Double glazing improves energy efficiency by reducing reliance on heating and cooling systems. Our aluminium sliding doors include a thermal break to reduce heat loss through the frame. This lowers the overall system U-value, improving your building’s thermal performance.
Understanding U-values is essential for assessing the thermal performance of sliding doors, since a lower U-value means better insulation. Our steel commercial doors achieve U-values as low as 1.5 W/m²K. Our sliding systems are engineered with the same thermal-efficiency focus, with exact figures confirmed on a project-specific basis.
Energy efficiency and effective insulation can help lower heating and cooling costs across your commercial building. Double-glazed sliding doors provide a major upgrade in insulation and energy efficiency over single-glazed options. They reduce heat transfer, keeping interiors more stable through the working day. Low-E glass reflects heat back into a room to improve insulation, and we also offer inert gas fillings and Warm Edge technology on request.
Double glazing offers substantial acoustic dampening compared to single glazing, since the dual-pane structure absorbs external noise. This benefits premises on busy roads or near other noise sources. Double-glazed sliding doors can also help maintain a higher inner-pane temperature, which reduces the risk of condensation forming on the glass.
Security & Safety Features
We offer increased security with multi-point locking and enhanced glass strength, keeping the entrance safer for staff, customers and visitors. This makes our sliding doors a more secure option for commercial entrances.
Double-glazed sliding doors typically use toughened or laminated glass depending on the specification. Triple-glazed sliding doors offer enhanced impact resistance where a higher specification is needed.
All of our automatic sliding doors are BS EN 16005 compliant, the European safety standard for power-operated pedestrian doorsets. They’re also a practical option for compliance with the Equality Act 2010, ensuring your entrances are accessible for all staff and visitors.
Choosing the Right Sliding Door for Your Building
The right sliding door depends on your opening size, footfall and building regulations. Multi-panel sliding systems suit large openings, accommodating wide entrances without losing floor space. Smaller openings often suit a simpler two-panel configuration.
Sliding doors can range considerably in size, so our team measures your exact opening during the site survey stage. This ensures the finished system matches your building.
Building regulations may apply depending on the project type and the building’s intended use. We factor this into the estimate stage, so there are no surprises later on.

FAQs About Double-Glazed Sliding Doors
Double-glazed sliding doors can reduce outside noise significantly compared to single glazing. The dual-pane structure and insulating gas layer both help dampen outside noise.
Sliding door systems can range considerably in size, from single small openings to large multi-panel runs. We confirm the exact sizing during our survey of your site.
Double-glazed sliding doors maintain a higher inner-pane temperature than single glazing. This reduces the temperature difference that causes condensation to form on the inside of the glass.
Some of the main reasons our customers choose double-glazed sliding doors include:
Maximum natural light and clear views from large glass panels
Strength, durability and slim sightlines from engineered aluminium frames
Easy, effortless access with sensor-activated opening
Flexibility to suit a wide range of openings and building types
Reliable long-term performance from low-maintenance running gear
