What are the advantages of sliding doors?

The advantages of sliding doors for patios and balconies

Sliding and lift & slide doors for patios and balconies have many advantages. Since no swivel space is required, sliding doors are a particularly space-saving solution. They also offer increased comfort, since sliding doors can be opened and closed without significant effort and cannot slam shut on their own. Patio sliding doors allow large opening widths to let the light into living and dining rooms. You can create an elegant visual extension of your living space and an unobstructed view into your garden. Sliding doors and lift & slide doors are ideally suited for patios as well as for balconies and conservatories.

Are heroal sliding doors barrier-free?

Barrier-free accessibility for your patio, balcony or conservatory

heroal sliding patio doors are available with low thresholds, including a zero-barrier door for barrier-free accessibility. Our barrier-free solution for sliding doors ensures both unrestricted passage through the door and protection against moisture damage in your living or dining area with the heroal DS drainage system. Surface water is diverted without any backflow. A sliding door can make your home more accessible in other ways as well. For large and heavy sliding doors in particular, you can also choose a motorised version for easy operation from a wheelchair. Automatic obstacle detection effectively prevents damage to objects and injuries that might arise from being caught in the door.
How good is the thermal insulation of a sliding patio door?

Top thermal insulation values and an ideal indoor climate with sliding patio doors

heroal sliding doors offer maximum insulation with UWvalues of up to 0.82 W/m2K. We use exclusively high-quality insulating materials. Thanks to innovative insulation technology, you can enjoy a comfortable indoor climate. This lift & slide door gives the interior of your living room a warmer feel than conventional sliding patio doors. The excellent insulation technology of heroal sliding doors can significantly reduce unpleasant draughts that are often caused by air that has cooled on the inside of the sliding door and sunken to the floor.
Do sliding patio doors provide burglary protection?

Burglar-proof sliding patio doors

In addition to an elegant and modern design and high ease of use, heroal sliding and lift & slide doors offer a high level of security. Particularly older patio doors often present weak points that burglars exploit. They are one of the most common burglary targets for single-family houses, as they are often not visible from the street. To increase burglary protection, heroal sliding doors can be equipped with anti-lift devices, drill protection, floor locking and safeguards at the centre joint as well as lockable handles. This provides burglar protection up to resistance class RC 2 (WK 2). This class means that the patio door can withstand a burglary attempt on each component with screwdrivers, pliers and wedges for at least three minutes. In that amount of time, most burglars will have already given up.
Aluminium sliding patio doors

The advantages of aluminium sliding patio doors

Compared to sliding doors made of other materials, aluminium sliding doors are particularly durable and weather-resistant. Aluminium sliding doors require limited maintenance and care. The high stability of aluminium allows for particularly large and elegant sliding patio doors. Would you like to give your aluminium sliding door a wood, concrete or rust look or design it in one of the many colours of the RAL spectrum? Our industry-leading, highly weather-resistant heroal hwr powder coating technology makes it possible to apply a variety of surface designs to the aluminium profile that will last for many years to come. Up to 85 % recycled aluminium is used for heroal sliding patio doors. With this process, 95% less energy is used compared to new aluminium, without any loss of quality.

The difference between lift & slide doors, sliding doors and parallel slide/tilt doors (PST)

Lift & slide doors

Lift & slide doors are opened by lifting and sliding sideways. Lifting the leaf during opening and closing does not cause any friction on the seals between the leaf and the frame. A smooth-running lever mechanism makes it easy to move particularly large elements, which allows you to create open living environments. Lowering the wing onto the frame also makes a very tight connection. Lift & slide doors can be built for barrier-free accessibility with a zero-barrier design. As the leaves of lift & slide doors are usually quite large and heavy, motorisation is recommended.

Sliding doors

Sliding doors are opened and closed by simply moving them without lifting the leaf. In contrast to lift & slide doors, sliding doors take less effort to manufacture and install. The fitting technology is also less complex. This generally makes sliding doors a more cost-effective alternative to lift & slide doors, though they generally have a higher frictional resistance when opening and closing than lifting/sliding doors. Like lift & slide doors, sliding doors can be built for barrier-free accessibility with a zero-barrier design.

Parallel slide/tilt doors

As an alternative to lift & slide doors and sliding doors, you can also use parallel slide/tilt doors for your patio or balcony. This patio door is based on the design of a window and can be slid open to walk through or tilted like a window for ventilation. It is particularly suitable for smaller door openings. In contrast to sliding and lift & slide doors, parallel slide/tilt doors do not provide barrier-free accessibility due to their construction.

Which sliding patio door is right for me?

heroal sliding doors and lift & slide doors are thoughtfully designed down to the last detail – you'll notice it from the very first time you use them. We will be surprised at how easily even large sliding door elements can be moved. Our sliding patio doors owe their superbly smooth running, long lifespan and comfortable operation to proven soft-close technology and the robust heroal stainless steel running rail. The functionality stays strong even after years of use. Other components such as handle and stop dampers can also be used to make heavy sliding doors operate even more smoothly. In addition, heroal sliding patio doors can be equipped with an electric drive. The drive can be conveniently controlled at the touch of a button and connected to your smart home system. Find the heroal sliding or lift & slide patio door that is right for your needs.
