Triple Track Doors

Triple track doors are particularly effective where homeowners want glazing to form a major feature of a room. The individual panels can be considerably larger than those commonly found in French or bi-folding doors. This reduces the number of vertical frame sections across the opening and provides wider views through the glass.

For properties throughout the South Lakes and Cumbria, this can be a significant advantage. Homes overlooking gardens, countryside, fells or other open surroundings can use large sliding doors to make much more of their setting.

Natural light is another consideration. Large glazed areas can help bring daylight deeper into a kitchen, dining room or living space. This can be especially useful in rear extensions, where the additional building depth could otherwise reduce daylight within the original part of the house. Triple track doors can also be combined with fixed windows, slim frame windows, shaped glazing and roof glazing to increase the amount of natural light entering a new extension.

Aluminium triple track doors are particularly suited to large glazed openings because of the strength of the material. Aluminium frames can support substantial glass panels while maintaining relatively slim profiles. This helps reduce the amount of visible frame and allows the glass and surrounding view to become the main focus.

Modern aluminium systems incorporate thermal breaks within the profiles to reduce heat transfer through the frame. Combined with suitable insulated glazing, this allows large sliding doors to meet the thermal requirements expected from modern external doors. Aluminium also provides considerable choice over appearance. Depending on the selected system, homeowners can choose from numerous colours and finishes to coordinate the doors with their windows and other exterior features.

Dark grey and black frames are often used for contemporary extensions, while lighter or more neutral shades can work well with stone, render and traditional properties. Where aluminium windows are already being installed, matching or complementary frame finishes can help create a consistent appearance across the project.

Homeowners planning a large glazed opening often compare triple track doors with bi-folding doors.

The two systems provide different benefits.

Bi-fold doors use several narrower panels that fold together as the doors open. This can allow a large proportion of the opening to be cleared, making them useful where maximum access between the house and garden is the main priority.

Triple track doors use larger sliding panels. Although part of the opening remains occupied by the stacked panels, there are generally fewer vertical frame sections across the glass when the doors are closed. This can make triple track doors particularly attractive where uninterrupted views are important.

Sliding doors also require no space for the panels to swing or fold outwards. This can be useful on smaller patios and terraces or inside rooms where furniture needs to be positioned relatively close to the glazing. The right choice depends on the dimensions of the opening, the surrounding space and whether you place greater importance on the size of the opening or the view through the closed doors.

South Lakes Windows can discuss triple track, patio, lift and slide, French and bi-folding doors as part of your project.

Large areas of glazing make thermal performance an important part of the specification.

Modern double glazed triple track doors use insulated glazing units to help reduce heat transfer. Low-emissivity glass and insulating gas within the sealed unit may also be used as part of the selected glazing specification. The frame and glass need to be considered together. Thermally broken aluminium frames help reduce heat transfer through the metal, while weather seals help protect the opening from draughts, wind and rain.

This is particularly important for properties in exposed parts of Cumbria and the South Lakes. The orientation of the glazing should also be considered. Large south and west-facing doors can receive considerable sunlight during parts of the day. Suitable glass specifications can be discussed where controlling solar gain is a priority.

Safety glazing will be required in appropriate areas because of the size and position of the glass. Laminated and acoustic glazing may also be considered where additional impact resistance or noise reduction is required.

The size and weight of triple track door panels make the quality of the sliding mechanism particularly important. Suitable rollers and tracks allow the panels to move smoothly along the frame. Handles and locking systems are designed to secure the panels when the doors are closed. A correctly installed system should provide straightforward everyday operation despite the size of the glazed panels.

Threshold design also needs careful consideration. A low threshold can make movement between the house and patio easier and reduce the physical division between the two spaces. However, drainage, external ground levels and exposure to the weather must be taken into account. Our team will assess these factors during the survey and explain the available options for the selected system.
