How Do Double Glazed Sliding Doors Work?

All double glazed sliding door types have many of the features of double glazed windows, but on a larger scale. Each door comprises a uPVC frame that holds a glazed unit made from two panes of glass held apart and sealed to form a gap between the panes. This gap may be filled with air but is more likely to contain an inert gas such as argon.

The gas provides insulation between the two panes of glass since it is a poor conductor of heat, unlike glass that is generally a good conductor. The set-up ensures one side of the glass remains warmer than the other side. This means the interior will be kept warmer than the outside in winter but cooler in summer.

A typical installation comprises double sliding patio doors, where one section is fixed and the other slides open or closed, although more sliding panels can be incorporated to cover wide spaces. The sliding sections run along tracks fixed to the floor and lintel.

What are the Advantages of Double Glazed Sliding Doors?

Double glazed sliding doors offer a range of benefits over traditional patio doors. Here’s why they’re a smart choice for modern homes and commercial spaces:

• Improved Energy Efficiency
  Double glazing provides excellent insulation, reducing the need for heating in winter and air conditioning in summer. Energy savings are even greater when combined with well-sealed frames and low-emissivity (Low-E) glass, which reflects heat and minimises heat gain. This leads to lower energy bills and a smaller carbon footprint.
• Enhanced Security
  Modern sliding doors feature multi-point locking systems and two panes of toughened glass, especially strong when using security glass, making them much harder to break into than older single-pane doors.
• Unobstructed Views & Natural Light
  With slim frames and large glass panels, sliding doors offer expansive outdoor views and allow plenty of natural light inside, creating a bright, airy atmosphere.
• Space-Saving Design
  Unlike bi-fold doors or French doors that swing open, sliding doors glide smoothly along a track and don’t take up additional space. This makes room layouts more flexible and furniture placement easier.
• Reduced Condensation & Healthier Living
  Double glazing helps maintain a comfortable indoor temperature, keeping the inside glass surface warmer in winter. This reduces condensation and helps prevent mould and mildew.
• Seamless Indoor-Outdoor Living
  When fully open, sliding doors provide easy access between your indoor and outdoor areas—ideal for entertaining or simply enjoying open-plan living.
• Noise Reduction
  Double glazed doors can reduce noise levels by up to 80% compared to single glazing—perfect for homes in busy or noisy areas.
• Effortless Operation
  Unlike older models, today’s sliding doors are lightweight and glide smoothly with minimal effort.
• Custom Ventilation
  The doors can be locked in any open position, allowing you to control airflow for perfect ventilation.
• Versatile Style Options
  Available in a range of designs, these doors suit both residential and commercial settings.
• Low Maintenance
  The durable uPVC frames resist warping, corrosion, and cracking. Cleaning is easy—just an occasional wipe with a damp cloth is all that’s needed.

Why Install Double Glazed Sliding Doors from Ultimate Windows?

The benefits of double glazed sliding doors are obvious and make an investment in them worthwhile. However, the double glazed sliding door price can be significant and is dependent on several factors:

• The size of the door, since a large door will need more materials and time to manufacture and install
• The design of the door and any particular features, with the price increasing with complexity
• Frame materials, since high quality materials are more expensive than sub-standard ones
• The type of glazing, which can be standard glass at the cheapest, but low-e coatings and toughened glass add to the cost
• Any particular installation costs, such as the complexity of access.

Buying the cheapest is rarely the best option since poor quality units will usually deteriorate quickly and need replacing prematurely, which adds to the cost.
