Terrace glass systems, awnings and shading systems create additional living room on the balcony or terrace. Furthermore, textile sunscreens offer protection from the weather and UV ray. As well, they shield inquisitive glances and can help you to save energy. In the LEINER ABC we explain the most important terms relating to our awnings and terrace glass systems as well as their different functions.
The 3d sensor is a special wind sensor from Somfy for use with radio-controlled motors (see also the lexicon entry for wind sensor). Attached wirelessly to the side of the front profile, it responds to the intensity of the movement of the awning, retracting it automatically if the wind gets too strong.
Awning fabrics are mainly manufactured with acrylic fibres. These are highly resistant to the strong effect of sunlight. They are also very tear-resistant and colour-fast.
The angle of inclination is set when the awning is mounted.
The name of the LEINER window awning series with a semicircular formed cassette. The cassettes come in a range of sizes to suit different window dimensions and fabric heights. The ARCO is available as a drop-arm and vertical awning (also wind-stable) or as a markisolette (see the lexicon entry for (markisolette).
The AREA classic is the cubic terrace glass system with a roof overhang. It is also available with a front-mounted rain gutter on request.
The AREA exclusiv is the cubic terrace glass roof with a flush front profile and without roof overhang. The rain gutter and drainage are integrated and concealed.
The AREA fix is the LEINER fixed glass system that protects your favourite spot from slanting rain and side winds.
AREA free is a motorised sliding roof window, that can be conveniently opened with io radio control. AREA free provides a bioclimatic effect to your glass roof.
The AREA led is our individual lighting system with dimmable LED elements for the AREA terrace glass system. It can also be retrofitted in the rafters of the AREA terrace glass system at any time.
The AREA slide system consists of all-glass doors, which can be opened and closed with just one hand. It can also be combined with other LEINER products, such as the PERGOLA SUNRAIN Q.
The AREA slim system consists of solid, fixed window elements that protect your favourite spot from slanting rain or side winds. The nearly frameless window elements offer maximum transparency and a virtually unrestricted view outside.
Arm brackets are among the most heavily used components of an awning. LEINER uses hardened aluminium. The arm brackets must withstand extreme leverage forces, as the folding arms of the awning are attached to them.
Modern awning fabrics are high-tech products. LEINER fabrics meet the strict requirements of the OEKO-TEX® standard.
(See also the lexicon entry for impregnation)
When opening the AREA free sliding roof window, the air below the roof is vented automatically. In the summer, warm air can escape upwards and cooler air can be drawn in under the roof.
See the lexicon entry for torsion bar.
This is the name of the side awning from LEINER. It protects against both sunlight from the side, inquisitive glances and light wind. So its a perfect complement for your terrace or balcony. It is attached to the wall and can be pulled out horizontally by hand. A spring-loaded roller ensures that the fabric always rolls up fully on retraction. The CALYPSO ROLL from LEINER is also available as a slanted system.
This is the name of the LEINER window awning series with rectangular formed cassette (see also the lexicon entry for ARCO). The CANTO is available as a drop-arm and vertical awning (also wind-stable) or as a markisolette (see also the lexicon entry for markisolette).
The cassette awning consists of extruded aluminium profiles. The entire mechanism of a cassette awning is hidden in the interior of these profiles when the cassette is closed. The profiles thereby protect the awning fabric and mechanism.
The ceiling rail is a so called guide rail. It primarily serves to guide the individual window when opening and closing the AREA slide. See also the lexicon entry for the AREA slide.
Our AREA terrace glass system is what is known as a cold roof. There is no thermal separation of the profiles, such as would be the case with a conservatory. Cold roofs offer sufficient protection from the sun and weather for private and business use. See also the lexicon entry for thermal separation.
LEINER offers single awnings up to 650 cm width. For larger widths, the coupled awnings are offered. Those are made of two or three awnings, which are coupled operated but driven by just one motor.
Manually operated folding arm awnings are equipped with a special gear. They are extended and retracted using a crank handle. LEINER cranks offer maximum user comfort.
During the fabric's processing, creases cannot be avoided at all. Held against the light, those creases can appear as lightly dark stripes. They do not impair the function or life of the awning fabric in any way.
See the lexicon entry for purlin.
The standard drive available for awnings is the electric drive. This is what is known as a tubular motor that is inserted into the fabric roller.
The SAFETY MOTION emergency manual drive is the contingency plan for your awning. If the radio-controlled motor does not work, the awning can be closed manually by crank with the emergency manual drive.
The emergency drainage integrated in all profiles of the AREA terrace glass system effectively prevents the accumulation of water and frost damage within the profiles because water and moisture are drained off before this can arise.
See the lexicon entry for emergency crank handle motors (SAFETY MOTION)
This is a mandatory certification for manufacturers and suppliers of structural steel and aluminium parts. In the European Union, terrace glass systems and cold roofs are required to have EN 1090 certification. Anyone places such systems on the market without the required certification is liable to prosecution in the event of an incident. Uncertified systems pose a high safety risk. LEINER meets all the requirements for this certification and is certified according to EN 1090 standard.
To protect users from awnings of lower technical quality and hence injuries, awning manufacturers have been subject to CE labelling requirements since 01.03.2006. In the consequence, no awnings without a CE marking may be put into circulation in the European Union. Essential parts of European standard EN 13561 include the safety wind load (see also the lexicon entry for wind resistance class) and the water load (see also the lexicon entry for rain resistance class).
Awnings help to save energy. The timely extension of awnings protects rooms from overheating. Especially in air-conditioned room, the cooling output of your AC can be reduced significantly.
Aluminium can be deformed under very high pressure. The extrusion process forces aluminium through a mould to produce profiles which can, for instance, be used as cassettes for cassette awnings.
The awning fabric is rolled up on the pivoted fabric roller. The awning drive (gear or motor) is also located in the fabric roller, which is usually made of steel.
See the lexicon entry for impregnation.
Fixing brackets are the components used to mount the awning to the wall, ceiling or on the rafters. In awnings with a torsion bar, this is suspended directly in the brackets. In cassette awnings, the cassette is connected to the brackets.
The floor rail is also called a slide rail. It primarily serves to guide the individual windows, when opening and closing the AREA slide. See also lexicon entry for AREA slide.
The folding arms are the most important components of an awning because they deliver the necessary tension for the awning fabric. In combination with a flyer chain, internal springs keep the fabric taut. LEINER folding arms are extremely long-lasting and characterised by almost uniform spring tension.
The folding arm parts are among the most heavily used components of an awning, which is why LEINER uses hardened aluminium.
Free-standing awnings are awnings that are fixed to a frame and are installed on large terraces or outdoor areas. They are used, if it might not be possible to mount on a wall. Also particularly large areas can be shaded by free-standing awnings. The frames of the free-standing awnings from LEINER are aluminium structures (e.g. GASTRO SUNRAIN).
The front profile is the front end of your LEINER awning and is also known as the drop profile. The awning fabric is attached to the front profile and transported forward as the folding arms extend. Also a valance may be attached to the front profile.
See the lexicon entry for free-standing awning.
This is a special aluminium alloy that is given additional hardness through a subsequent thermal process. The material guarantees long life and resistance and meets the highest safety requirements. The special LEINER manufacturing process doubles the resistance and results in a durable strength of up to 350 N/mm². Thanks to the hardened aluminium, even awnings with a projection of 4 metres and on the other hand heavier profiles with an additional VARIO-VOLANT valance can be realized.
The finish or impregnation of the LEINER awning fabrics protects the fibres from environmental influences. It repels dirt, fat, water and oil. The lotus effect known in nature is imitated through special textile finishing processes, preventing the formation of mould and algae on the fabric.
The bidirectional radio protocol is a reliable and secure technology with a data feedback function. This allows users to check the status of the sending device at any time and from anywhere. The operation is designed for mobile remote control via smartphone. The io radio technology is the basis for a smart home and can be expanded and retrofitted at any time.
Laminated safety glass (VSG) consists of at least two layers that are bonded together with a separating film to form a single unit. In the case of glass breakage, the place of breakage remains closed because the shards stick to the film. Should the glass in the AREA terrace glass roof break, the use of laminated safety glass prevents injuries. See also the lexicon entry for overhead glazing.
The LEINER LOUNGE COLOURS are used for the awning components and are characterised by a very finely structured surface and special metallic effect. The particularly high-grade powder coating is available in a total of 18 colours and is also extremely robust.
This is the convenient standard locking and operating variant for our AREA slide glass system.
The markisolette is a particular kind of window awning. It is a mixture of vertical and drop arm awning. The fabric first runs vertically, then the drop arms (approx. 60 cm) bring it to an angle of up to 140 degrees via a deflection pulley.
Where installation space is confined, the TREND narrow awning is the right solution.Thanks to the crossing folding arms, more projection than width can be provided – while retaining stability.
Open folding arm awnings do not have profiles that protect the awning fabric and mechanism from the wind, weather and dust. They are therefore especially suitable for mounting under balcony ceilings or eaves. However, a rain hood is available as an optional extra (see also the lexicon entry for rain hood).
If glazing is inclined at an angle of more than 10 degrees, it is defined as overhead glazing. For overhead glazing, laminated safety glass (VSG) is mandatory in most of the European countries. See also the lexicon entry for laminated safety glass.
LEINER aluminium components are almost always powder-coated. In powder coating, a coloured powder is sprayed onto the surface to be coated; then the powder is "baked on" by thermal treatment. Powder-coated surfaces are characterised by high resistance and colour fastness.
This high-performance PVC fabric was especially developped as an awning fabric. Précontraint 302 is used with SUNRAIN awnings and 100% watertight. Furthermore this awning is odour neutral and flame retardant (EN 13501-1, class B1), stable in length and easy to clean. Précontraint 302 offers the highest sun protection factor of 80 – even in white.
See the lexicon entry for VARIO-VOLANT valance.
The length of your LEINER awning is also called the projection. The projection is measured from the wall to the front profile, when the awning is extended at an inclination of about 15 degrees.
This is the key component of the SUNRAIN awning, patented by LEINER. Movably mounted on the folding arms, two purlins per SUNRAIN awning support the fabric awning to help counteract the sagging effect. Kept taut, the fabric allows rainwater to run off.
See the lexicon entry for Précontraint 302.
An electric engine can also be driven by an additional external radio receiver. When retrofitting, this is recommended.
The radio-controlled motor is an electric drive with integrated radio receiver. The drive can be operated easily via remote control. Since a regular connected switch is unneccessary, low mounting costs are just one of the advantages.
A rafter fitting, or rafter bracket is needed to mount the awning on a rafter.
When it rains normal awnings are only limited usable. Special rain awnings allow water to run off in a controlled manner. These were developed specially for use in both rain and sunshine (see also the lexicon entry for SUNRAIN).
Thanks to an integrated rain gutter in the front profile, water runs off to the side.
When an open folding arm awning is retracted, a rain hood protects it from dirt and weather. This also so called hood profile, is particularly recommended if the awning is mounted on an unprotected facade. As an alternative, LEINER offers a patented, adjustable hood profile, which can be adjusted optimally to the awning's inclanation.
See the lexicon entry for SUNRAIN.
The rain resistance of the awning fabric depends on the material used. Acrylic fabrics have a water-repellent impregnation and can be used in light rain if the awning is tilted appropriately. However, 100% waterproof PVC fabrics (Précontraint 302) are preferred, as they can be used without damage even in constant rain.
European standard EN 13561 classifies awnings into three rain resistance classes: 0, 1 and 2. Class 0 awnings are not suitable for use in the rain. Class 1 awnings can withstand up to 17 litres of rain per square metre per hour, class 2 awnings up to 56 litres per square metre per hour. Caution: The rain resistance class does not say anything about the possible formation of pockets of water on the awning fabric. The SUNRAIN model from LEINER is the only awning in the world to meet the criteria for rain resistance class 2 at an inclination of five degrees (as a single system).
If the awning is fitted with an electric drive, it can also be controlled via rain sensor. When the rain begins, it automatically retracts the awning.
If the awning is inclined appropriately, rainwater can run off in a controlled manner. However, not all awnings can be used, when it rains. If the fabric of an awning is retracted when wet, it should be extended again at the next opportunity so that it can dry. Otherwise mildew stains might occur.
Before stitching, the awning fabric is doubled in the manufacturing process. When the fabric is rolled up on the fabric roller of your awening, different winding diameters are created around the seams. Because of the tension of the folding arms as well as the sagging of the profiles, corrugations result. If they are exposed to rain, especially acrylic fabrics strongly tend to corrugations.
The roof depth of an AREA classic system is the distance from the rear edge of the wall connection to the end of the overhang, but without a gutter. The roof depth of an AREA exclusiv system is the distance from the rear edge of the wall connection up to the front edge of the rain gutter.
This is the total width of an AREA glass roof. The total width includes the side covers on the left and right, which measure 19 mm, each.
See the lexicon entry for emergency crank handle motors (SAFETY MOTION)
Semi-cassettes are characterised by a large front profile. The profile protects fabric and mechanism against wind and rain from the front. In this awning model the rear is usually not protected.
The awning fabric is kept taut by a permanent spring system. The seams and hems have a reinforcing effect, but must at the same time be able to withstand the highest loads. The side tracks are additionally exposed to the wind. These forces can lead to elongation of the material and sagging side hems.
When coupling two or three awnings, slits arise between it. These cannot be covered by the awning's fabric. To cover these gaps, a slit cover is installed on a spring-loaded roller. It is moved automatically when the awnings are retracted or extended.
A household in which appliances communicate with each other and centrally controlled. Motorised sun shading systems can be integrated into a smart home. They are controlled via mobile devices or PC.
When Somfy's io technology is integrated in a product, this product is SMART HOME READY and can be used as first step into a smart home. All products marked with the SHR label can be integrated in a Smart Home, either directly or retrofitted. So, those products meet all requirements for the integration into a smart home.
The snow load is the force which snow applies on structures due to its own weight. This is depending on your region and the altitude above sea level. For a proper and, above all, safe configuration of your terrace roof, it is essential to know the snow load defined for your district. The regional snow load class defines which roof sizes can be realized. No roof can be mounted safely, if the regional snow load is ignored. See also the lexicon entry for snow load zones.
The potential snow load is calculated on the basis of the snow load zone in which the structure is located. This forms the basis for the correct static dimensioning of the roof (e.g. size, load) in the corresponding region. Germany, for instance, is divided into 5 snow load zones, whereas France is divided in 8 zones. You will find further information about the snow load zone of your location by using a search engine, where you can search for pictures by using the terms "Schneelastzone" or "snow load". For safety reasons, the snow load zone must always be considered. Please ask your LEINER specialist partner for advice. See also the lexicon entry for snow load.
A split VARIO-VOLANT valance (see also the lexicon entry for VARIO-VOLANT valance) consists of two separate vertical fabrics suspended at the front profile of your awning. Both valances can be operated separately. Thanks to this optional extra, the shade can be adapted exactly to the course of the sun, especially in very wide awnings.
LEINER's structural standard is a type-tested static calculation for the terrace glass systems manufactured in-house. All LEINER AREA terrace glass systems have been statically calculated. All calculations are verified and approved by the responsible building authorities.
If an awning is used to protect a room from overheating or glances, a sun sensor might be helpful. The sensor extends and retracts an electrically operated awning dependend on the sunshine. Sun sensors can be accompanied by wind monitors. (see also the lexikon entry for wind sensor)
Sun protection might be the best known quality of an awning. Fabrics absorb sunrays (see also the lexicon entry for UV-protection), and prevent heat from terraces and balconies. Also large glazed areas and sunrooms can heat up quickly. Attached on the outside, awnings have a positive climatic effect, without the immense engergy consumption of an AC.
It is mounted on a sun room's roof. So, the conservatory or sun room is protected from overheating.
Conventional awnings with normal awning fabrics are hardly suitable as rain protection. SUNRAIN awnings are a patented innovation from LEINER and registered as a trade mark. They were developed specifically for use in both sun and rain and are fitted with a 100% waterproof PVC high-performance fabric (see also the lexicon entry for Précontraint 302). Whereas awnings usually require an inclination of at least 15 degrees, the rainwater runs off from a SUNRAIN with an inclination of just 5 degrees. The special geometry of the folding arm also creates more "space" below the awning.
SUNSHINE awning systems are pure sun protection products. You can choose between free-standing awnings (GASTRO SUNSHINE) and pergola systems (PERGOLA SUNSHINE). Both produtcs are also availabe as SUNRAIN version, protecting against sun and rain.
Awnings marked with "SZ" are windstable awnings with a zip track in the side guide rails, known as the ZIP system. The maximum wind load capacity depends on the size. At LEINER you can find SZ-awnings for windows, sunrooms and glass roofs.
Thermal treatment of the glass gives Tempered glass (ESG) new material properties that deliver greater safety. If the glass breaks, ESG declays into small, blunt-edged pieces that present a lower risk of injury. ESG is also extremely resilient as well as bend and impact resistant. ESG is used in the AREA fix and AREA slide.
The perforated, slightly transparent fabric is particularly suitable for VARIO-VOLANT valances or side awnings. This fabric provides a view to the outdoor scenery and creates a pleasantly light atmosphere. On the other hand, it protects against inquisitive glances from the outside.
In the particularly wind-stable terrace folding roofs PERGOLA SUNRAIN, the awning fabric is folded. Several cross-purlins create the stability of the system. Since the terrace folding roof can be used with wind strengths up to 9 Beaufort (depending on size), it is an interesting alternative to classic terrace roofs.
The AREA terrace glass system is a cold roof in terms of design and is available in the 'AREA exclusiv' and 'AREA classic' versions. See also the lexicon entry for cold roof.
In thermally separated aluminium profiles, the two hollow profile halves are separated by internal insulation material, which means that the heat or cold of the metal is not transmitted to the outside or inside. Thermal separation also prevents the formation of condensation. See also the lexicon entry for cold roof.
The tilt function of the arm bracket (see lexicon entry for arm bracket) ensures a lastingly reliable closing action, particularly in cassette awnings. Arm brackets of less sophisticated design often do not stay closed. The integrated windlock clip in the tilt joint bracket also stabilises the folding arms in light winds.
The arm brackets with the folding arms as well as the fixing brackets both are attached to the torsion bar. All forces are transmitted from the awning fabric to the fastening in the awning in the brickwork by the torsion bar. So, the bigger the dimensions of the torsion bar, the bigger the forces that can be handled. LEINER uses torsion bars of size 40 x 40 millimetres.
This is fitted below glass terrace roofs. The underglass awning is designed to be particularly suitable for areas protected from the wind.
As the intensity of UV rays continues to rise, so does also the danger of sunburn or skin cancer. Awnings with UV 801 certification offer very good protection from these rays. The precise level of UV protection (40, 60 or 80) is indicated on the information material provided with the awning fabric.
Valances are short lengths of fabric in a variety of forms that are attached to the front profile of the awning. They are a decorative element and conceal the mechanism in many types of awning, but are also suitable as advertising space for the commercial sector.
A VARIO-VOLANT valance is an awning fabric that can be steplessly rolled up from the front profil. It provides privacy from the neighbourhood and provides shade, even when the sun is low. An awning without a VARIO-VOLANT valance is of very limited use on west-facing terraces, which are often exposed to the sunset. The shaded area is enlarged by simply extending the VARIO-VOLANT valance, for which a range of special fabrics as well as the normal awning fabrics are available. All VARIO-VOLANT valances from LEINER can also be controlled automatically by remote control on request.
If an awning is used in the rain, water pockets will be formed. If the awning is not inclined at a sufficient angle, the fabric will sag under the water, because it is unable to flow off. Depending on the amount of water, this can result in damage to the awning. Awnings usually need an angle of inclination of at least 15 degrees, although the patented SUNRAIN awnings from LEINER need only 5 degrees for controlled water run-off.
The waterproofness of an awning fabric depends on the material used and how the seams are processed. The waterproofness is often stated as the height of a water column, indicating the resistance to the penetration of water. A normal awning fabric has a water column rating of approx. 300 millimetres. With an additional coating, a rating of up to approx. 1,000 millimetres can be achieved. However, the stitching of awning fabrics results in potential leaks at the seams, whereas if the seams are welded the fabric is completely waterproof, regardless of the amount of rain. PVC awning fabrics are a completely waterproof alternative.
The width of the awning is by definition greater than the width of the awning fabric.
The Wind Protect System WPS is an innovation of LEINER and was originally developed for the more stringent requirements of awnings for the gastronomy. Fixable supports on the front profile significantly enhance the wind stability of your awning. Depending on the size of the awning, the WPS offers protection from winds of up to wind strength 8, even in the event of sudden gusts of wind.
See the lexicon entry for Wind Protect System (WPS).
European standard EN 13561 classifies awnings into various wind resistance classes. There are four classes: 0, 1, 2 and 3. Awnings usually meet the requirements of wind resistance class 2. However, what is important is whether the awning can also be mounted appropriately to its class, and this depends mainly on the mounting surface. The indicated class can usually be achieved by mounting on concrete. To reach this class may be difficult to impossible in the case of lighter building materials.
The wind sensor protects an electrically operated awning from damage if there is too much wind (see also the lexicon entry for sun and wind sensor). The control system detects the wind strength via a wind wheel or wind sensor and retracts the awning automatically.
The cable guide bracing of the PERGOLA SUNRAIN model increases stiffness and wind stability in the unopened state.
