Opening types and designs for French doors

French doors from heroal are available in many different designs. Depending on individual requirements, doors with one or two sashes and different opening types can be created. The opening type is important for the required use of the door later on. French doors are available with sashes that you can only turn open or tilt and turn open. French doors with two sashes, but without a central joint or mullion, are a very appealing solution, providing for very convenient, wide passageways when they are open. Depending on individual requirements, balcony or patio doors can open inwards or outwards. heroal French doors offer the best solution for every installation situation. Please see here for a selection of the opening types available.

Features of heroal French doors

  • Full accessibility

    French doors offer fully accessible passageways

    French doors are a very convenient solution to create fully accessible passageways in your home. With a maximum threshold height of 20 mm, heroal French doors comply with the regulations of the German industry norm DIN 18040 for the construction of accessible buildings.

    Additional optional accessories increase the ease of use and security of your French door. The electric window drive heroal WF Drive allows you to automatically lock or unlock, or tilt your French door by a push button, remote control or app. This drive can also be integrated in standard smart home systems. The optional drainage system heroal DS protects fully accessible passageways against water ingress, and drains off rainwater without any backflow.

  • Burglary resistance

    This is how secure heroal French doors are

    Patio and balcony doors are popular targets for burglary attempts. Burglar resistant French doors made from aluminium help you to protect your home. Aluminium is a material that offers the best stability and resistance. The modular design of your French door and various security components, such as the number of locking points, lockable window handles, burglar resistant safety glass, fittings with mushroom head lock and anti lift devices ensure that burglary protection including resistance class RC 3 can be achieved. This means that a heroal French door withstands break-in attempts using a screwdriver, crowbar and simple drilling tool for at least five minutes. heroal French doors have been tested and approved by the independent German institute “Institut für Fenstertechnik“ (ift Rosenheim) and, in accordance with German industry norm DIN EN 1627, have received resistance class certification including RC 3. In combination with heroal safety roller shutters made of stainless steel, heroal French doors even have RC 4 certification, and thus protect even against experienced perpetrators.

  • Thermal insulation

    How to avoid energy losses

    Precious energy is often lost through insufficiently insulated windows or doors. heroal French doors stand out for insulation values (UW) of up to 0.72 W/m2K, and have received passive house certification by the German Dr Feist Passive House Institute. Thermally separated profiles, innovative fitting technology, and perfect profile geometries keep the energy loss through aluminium French doors to a minimum. The efficiency of a French door in terms of thermal insulation and heat transfer is expressed by the U-value (heat transfer coefficient). The U-value describes how much energy per m2 surface of a French door is lost from inside to the outside. The lower the U-value, the less heat is lost, and the more energy-efficient is the French door. The insulation value required for your French door also depends on the building as a whole. An insufficiently insulated old building, for example, needs to fulfil other requirements than a modern passive house. Therefore, it might be a good idea to get additional information from a professional energy consultant.

  • Sound insulation

    Sound insulation for French doors

    Being exposed to permanent noise pollution has a negative effect on our well-being and health. To keep the noise out and make you feel perfectly fine, heroal French doors are available with sound insulation including class 5, according to German industry norm DIN 4109. Thanks to the modular design of heroal French doors, the sound reduction index can be adapted to your individual requirements, or already existing elements, for example windows. Sound levels may be reduced by up to 48 decibels. To achieve this, the thickness of the glass as well as the professional installation of your French door play an important role, but also the frame profile including sealants, the set-up of the sealing zone, the face width, the foam filling, and the material used. Aluminium is perfectly suited for soundproof French doors, thanks to excellent thermal insulation values. heroal developed its own foam fill process for frames and sashes of French doors, which does not only ensure that the profiles are 100 % filled, but also stands for the ideal reflection and absorption of noise. This way, excellent sound insulation can be guaranteed even with slim face widths.

    The requirements on sound insulation may be quite different. To enjoy perfect comfort of living, ask your heroal partner to find out which sound insulation class is best for you. Use our heroal specialist partner search to find a suitable fabricator near you.

  • What is the maximum width of a French door?

    heroal French doors can be manufactured up to a sash width of 1,600 mm. A fully accessible solution is possible up to a width of 1,200 mm. French doors with two sashes can be created up to a sash width of 1,200 mm per sash (also as fully accessible version). Without a central joint, they are particularly suited for very large passageways. Fully accessible (barrier-free) doors with step-free thresholds are not only recommended for wheelchair users and people with restricted mobility, but also reduce the risk of tripping hazards. The width of the door opening is decisive in order to be able to pass through the door conveniently. The German industry norm DIN 18040-1 recommends passageways that are at least 90 cm wide.

  • How to properly adjust a French door?

    French doors should only be adjusted by a professional business in the window installation industry. Please carry out regular maintenance and inspection works in order to ensure that the function and ease of movement of the high-quality heroal fittings are maintained for a long time. Please feel free to ask the company that installed your French door for help, if required. Alternatively, you can use our specialist partner search to find a suitable fabricator near you.

  • What insect screen is suitable for French doors?

    Protect your home against uninvited insects with a suitable heroal insect screen . Frequently used passages to go out on the terrace or balcony allow mosquitoes, flies or wasps to enter your rooms. heroal insect screens are individually manufactured according to your requirements, and custom-fit to your French window. The wide range of different types of fabric (gauzes) not only offers various design options, but also special fabrics for allergic people and pet owners - and all this with maximum air permeability and transparency. Thanks to the durable and highly weather resistant heroal hwr powder coating of the aluminium components, the insect screen can be perfectly colour-coordinated with the French door, creating very subtle looks.

    Pivoting frame

    The heroal pivoting frame is particularly suited for frequently used French doors. In addition to effective insect protection, it is characterised by robustness and durability and, in combination with a high-quality fabric, ensures a long service life. The pivoting frame can open either inwards or outwards. As a swing door variant, the insect screen can be opened flexibly, inwards or outwards. This means you can easily pass through the swing door in both directions, even if you don't have a hand free. The automatic closing function ensures ideal protection against insects.
