Sliding patio doors

heroal sliding doors offer maximum insulation with U_W values 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.

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.

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.

heroal sliding doors and lift & slide doors for patios, balconies and conservatories are available in many different designs. Depending on the type of opening, doors can be fitted with single, double or triple-track frames and with up to six movable leaves. This means that your sliding door can not only be adapted to your individual requirements, but is also suitable for use in extra large building openings to create maximum transparency and open panoramas. In addition to the use of all-glass corners for maximum light and transparency without supports to block the view, the 90° opening corner is a special highlight. Corner areas can be opened completely without crossbars or supports blocking the panorama.
