Unlike a simple sliding door – which is pushed from one side to the other on a track – a lift-and-slide door is moved by running wheels located in the frame.
To open the door, the handle is moved to the appropriate position, the sash is lifted slightly and then simply rolled to the side. Since lift-and-slide doors are often heavier than ordinary slide doors, the running wheels are a great relief when opening and closing the door and give the impression that the sash is almost floating.
Similarly, closing the door is just as easy as opening it. No matter whether you are young or old:
Sliding doors impress with their simple and safe operability. The lifting technology not only looks elegant and simplifies the opening and closing of the lift-and-slide door, but it also ensures that the door is closed particularly tight.
The sash does not simply close above the running track but lowers into the profile. The sliding door is therefore significantly tighter than other doors and not only particularly well protected against wind and weather, but also makes a valuable contribution to thermal insulation.
In this way, you can protect both your wallet and the environment with your slide patio door.
Things to know about sliding doors
The construction of a lift-and-slide door
Like any door, a lift-and-slide door consists of a frame and a corresponding panel. In the case of glass doors, the glazing doesn't only give you a clear view of the outside but can also perform other important tasks.
Depending on your own requirements, different types of glass can be chosen, each of which can set special priorities with its individual properties. At the end of the process is the installation at the actual place of use of the sliding door.
Like all windows and doors, there is a choice of different materials for the sliding door. In addition to uPVC, wood and aluminium, the wood-aluminium combination is particularly popular, as it combines the best properties of the two individual materials. So, you have the beautiful appearance of a wooden frame inside – which at the same time ensures regulated air exchange and good thermal insulation – while outside a robust aluminium cladding provides the necessary protection against rain and strong winds. Aluminium is also a very easy-care material from which dirt and traces of use can be removed without much effort.
Outdoor weather damage – as can occur with wooden frames – is no longer a problem with this combination.
Glazing can provide additional focal points in the range of services for both windows and doors. Among others, the following options are available:
- Insulating glass
- Soundproof glass
- Safety glass
The use of insulating glass clearly places the focus on thermal insulation. It is an important topic for homeowners and can no longer be ignored.
Windows and doors – especially front doors – must be professionally insulated to prevent heat loss. This is a burden on the environment and also costs money over time.
Multi-pane insulating glass can have a major impact on saving energy. The thermal insulation values, or the values for the heat transfer coefficient, are nowadays best with triple glazing: with this, energy can be saved very efficiently.
Especially in combination with special uPVC frames, which are featured with multi-chamber profiles at windows24.com, excellent results can be achieved here.
Soundproof glass is also a sensible investment for a slide patio door. Since these are generally thicker than other French patio doors, the sound insulation is already better through the frame than with ordinary models.
In combination with soundproof glass, a sliding door can provide excellent protection against noise. Depending on the expected noise pollution, three different classes of sound insulation glazing are available.
A house that is built in the immediate vicinity of busy roads therefore requires better sound insulation than buildings that are located in a rather quiet environment.
The highest level of sound insulation reaches a value of 43 decibels. This means that sound arriving at the window pane is attenuated by this value. For comparison: a value of 10 decibels is already equivalent to a halving of the noise perceived by humans.
Those who focus primarily on safety are well advised to use safety glass. In this category, too, various products are offered that provide different services in this area. You can choose between toughened glass, laminated safety glass and impact-resistant glazing.
While toughened safety glass considerably reduces the risk of injury in the event of a fall, laminated safety glass already offers genuine break-in protection. The film inserted between the panes under heat and pressure makes it almost impossible for unwanted visitors to penetrate the glass. This is because not only would the pane have to be destroyed, but also the very tear-resistant, tough-elastic film.
In addition, the risk of injury is also reduced with this model, as no large shards are produced if the panes are broken. However, the best break-in protection for sliding doors – but also for windows and other glass doors – is provided by impact-resistant glazing.
This is offered up to category A3 and thus guarantees excellent protection against burglary. For a particularly secure sliding door, it is advisable to install special security devices in addition to the appropriate glass. Only the fittings, in combination with an already stable frame and the right glazing, make the break-in protection of the door complete.
To manage with the weight of the doors, it is recommended to install them in pairs or groups. As a team, you can tackle the steps together, prevent injuries and check all seals and reveals.
This is the only way to take full advantage of the thermal insulation benefits of the sliding door. Improper installation can result in thermal bridges in the door, which not only prevent energy saving:
In the worst case, mould can develop from the resulting condensation. This is very hazardous to health and can penetrate into the masonry.
Removing the mould afterwards is a time-consuming and costly affair and should be avoided at all costs. The correct installation of the sliding door is therefore particularly important.
Up to date with the lift-and-slide door
Compared to the usual French doors, a door that slides has a number of advantages in addition to the features already mentioned. The sliding function, for example, allows the door to be opened in a space-saving manner. The space in front of and behind the sliding door can therefore be used optimally, as no consideration has to be given to opening or closing swinging sashes.
In addition, a sliding door makes large glazing possible, which appears modern and elegant, but also allows significantly more natural light to fall into the room compared to smaller French doors. This makes the room look friendly and inviting; moreover, artificial lighting can also be saved.
Natural light is also usually warmer than artificial light and thus saves energy even in autumn or winter. This not only saves money and energy but also actively contributes to the feel-good factor of your own four walls.
Installing a sliding door is therefore a decision in favour of a modern product that makes it more than just a simple door. The sliding door meets the highest demands in terms of quality as well as design and enables more than just compliance with current regulations. In fact, it exceeds the requirements placed on doors and windows many times over and creates a homely and inviting atmosphere.
