Why
is right for you
The ENERsign®primus combines the narrow and elegant traditional window frames with the technical achievements of the modern age. With its innovative concept, primus inspires experts and sets standards in today’s window technology.


ENERsign®primus, the world’s first coordinated complete system for windows, sliding doors, front doors and shading is different from existing generations of window and sliding door systems. Because for the first time, ENERsign® primus, with its minimalist elegance, can be matched to the architecture with its slim, symmetrical design and particularly high aesthetic standards. The external appearance of the house remains uniform – design meets quality.
From the inside, the wall-integrated ENERsign®primus wood-aluminium windows offer a cosy homeliness made of local natural woods. The circumferential slim frame profiles and generous glass surfaces form a harmonious unit.
The frameless sash view (integral frame) always guarantees a continuous horizontal glass line even with fixed and tilt and turn elements. From the outside, the windows captivate with a narrow frame perfectly integrated into the building envelope.
The ENERsign® shading elements are also installed concealed in the wall as a complete system.
Trust in our more than 25 years of development experience and our highest quality standards “Made in Germany”.
The ENERsign®primus wood-aluminium window is the premium window with the best insulation values.
The ENERsign® products are ideal for energy-efficient renovation and the construction of passive houses, zero-energy houses, plus-energy houses and KfW Efficiency Houses 40 and 40+.

The flush threshold ENERsign®primus lift-and-slide door can be opened and closed with ease thanks to the precise guidance at the top and bottom – and all this with a maximum sliding leaf weight of 500 kg. It is also available in different opening types – tailored to your individual architecture. It also sets standards in height (up to 2,800 mm) and overall width (up to 10,000 mm).
Operating convenience and technology at the highest level
The certified wood-aluminium ENERsign®primus lift and slide door with barrier-free threshold combines a first-class level of workmanship with a statically balanced construction. It also offers high tightness, excellent thermal insulation values and reliable burglary protection.
The ENERsign®primus lift-and-slide door is a dream and an eye-catcher in every house thanks to its sophisticated technology, the large glass surfaces to be realised and the narrow face widths all round.
The likewise certified ENERsign® primus front door meets all requirements such as driving rain tightness, stability and increased burglary protection. The lock automatically locks the front door in the main latch and in two additional locks – one in the upper and one in the lower part of the door. The door is thus locked at 3 points – a maximum of security, even when unlocked.
The phA certified terrace door with flush threshold is another highlight of the highly thermally insulated ENERsign® product family.
Thermal separation from the inside to the outside is decisive for optimum thermal insulation. This is guaranteed by the terrace door due to its sophisticated design.
The surface temperature on the inside of the optimally thermally separated bottom sash profile is almost the same as the room temperature. This avoids the risk of condensation and mould formation in the area close to the floor.
The ENERsign®primus balcony door also meets all requirements such as driving rain resistance, stability and burglar resistance.
Visually, the comfort threshold and the all-round slim profile form a harmonious unit.
With ENERsign®primus the fittings are fully concealed and integrated into the window. So nothing disturbs the perfect symmetry of the window and door elements. If hinges are required for static reasons, they are finished in stainless steel look.
the healthier wood color
- No biocides – No environmental toxins
- free from isothiazolones – free from microplastics
- does not evaporate – odourless
- Harmless to the environment
- Safe for humans and animals
RHENOCOLL HealthyColour acts physically on the surface and coats enzymes and also sugar molecules there. Thus the food base is blocked for colonists on the surface, a settlement on the surface does not offer a basis for life anymore. Thus the room hygiene is supported, which helps especially allergy sufferers.
The weather resistance of exterior paints is significantly increased and interior paints look fresh, new and clean for longer! This is achieved by a clever selection of environmentally friendly raw materials. By specifically avoiding biocides in the HealthyPaints, they also protect insects (e.g. bee deaths).
Woodstains can be used indoors and outdoors equally, as they do not evaporate! Due to the conscious avoidance of harmful substances, they are therefore completely harmless to humans and animals.
At primus, many components such as glass spacers and seals are kept in restrained matt black, providing a basis for many colour combinations indoors and outdoors.
Simple and elegant in design, ENERsign®primus is available in many RAL and design colours.
Modern architecture is characterised by large glazings. Floor-to-ceiling windows and balcony doors are also planned for the upper floor. For the sake of the visual appearance and to be able to enjoy the view undisturbed, a balcony or terrace is often dispensed with. But also for structural reasons it is not allowed to build a balcony in most city centres.
The fall-protecting parapet glazing ENERsign®glasguard, which is integrated into the side of the window frame, forms a technically perfect solution together with the wood-alumium window ENERsign®primus.
An architectural highlight
With the all-glass balustrade protection for windows and floor-level elements, we offer modern architecture a filigree and smart solution. A very narrowly held glass edge protection forms the conclusion at the top.
The glass parapet is hardly visible from the inside and allows an unobstructed view outside. Likewise, the overall appearance of the façade is hardly impaired.
Modern, high-quality and easy to use is the latest version of the insect screen FLYLOCK by ENERsign® – developed for large openings and especially for ENERsign® windows, balcony and lift and slide doors.
The sliding pleat integrated in the window frame is simply pushed to the side thanks to the pleat technology. We supply the ENERsign® flylock insect screen, in a first-class material selection and processing, already built into the window and door elements ENERsign®primus at the factory.
ENERsign® flylock:
Almost invisible but effective. So inconspicuous and elegant you can keep annoying insects out. Thinking symmetry to the end.
ENERsign® stands for wood-aluminium windows and doors with the highest standards of energy efficiency.
The best insulation and air-tightness values can be achieved through the interaction of design and material selection.
The narrow face widths of the window frames offer little contact surface with the outside climate. More glass surface also means increased solar gains in the winter and transitional periods.
The psi value of the glass edge seal is one of the best on the market.
The energy losses can be considerably reduced compared to “normal” windows.
The ENERsign®primus window achieves Uw-values of 0.45 W/m²K and R-values of 12 depending on the glazing and wood type.
Wood and aluminium a perfect combination. Inside a warm and comfortable wooden surface. Outside a weatherproof aluminium shell.
The thermal insulation in front of the frame reduces the thermal loads on the wooden frame. Even with large temperature fluctuations, the window remains dimensionally stable.
The high-quality fittings and sealing materials are designed for a long service life.
Wood is our passion. For decades we have been paying special attention to this material.
With the result that the unique and exclusive character of this natural material is shown to its best advantage.
Matt surfaces are becoming increasingly important as an optical counterbalance to high-gloss furniture and furnishing elements. Especially when they appear almost “untreated”. Our surfaces are optimally protected without losing even a single piece of their naturally exclusive charm.
Our treated wood does not release any volatile organic compounds (VOC) into the environment, making our window frames suitable for sensitive areas such as kitchens or bedrooms.
Wood inside, aluminium outside. In combination with the many convincing ENERsign® details, individual overall solutions can be realised. Our angular frames effectively underline the slim, reduced ENERsign® design. ENERsign®primus creates the perfect frame for special views.
System-integrated glass fall protection, reveal profiles, shading, insect pleated blinds and other details present themselves as a coherent overall concept that inspires with its consistently reduced appearance. Maximum interior atmosphere combined with a reduced, flush exterior appearance.
The extremely narrow face width of only 100 mm sets standards in architecture. Different types of wood and surfaces allow maximum design freedom. With a U-value window of 0.60 W/m2K, the ENERsign® primus window system achieves top values in thermal insulation.
The ENERsign®glasguard fall protection system can be integrated flush into the profile of the window reveal, thus ensuring a clean wall finish. Can be combined with ENERsign®primus windows and sliding doors, this elegant solution fits perfectly into the existing overall architecture and allows an unobstructed view of the outside.
Soundproofing
SILENT. COZY. QUIET.
The effects of noise are unpleasant and can have a negative effect on the human organism if the intensity and duration are appropriate. Noise is perceived through fluctuations in air pressure, which are picked up by the human ear and transmitted to the brain. The sound insulation of a window is measured in decibels. The higher the numerical value, the better the sound insulation. The sound insulation indicates how much sound energy is transmitted by the original sound energy. With an insulation of 10 dB, 1/10 of the original sound energy is transmitted, with 20 dB 1/100, with 30 dB 1/1000 etc.; a reduction of 1 dB is perceived by humans as halving the volume. The sound insulation of the window depends on the frame material, insulating glass, tightness of the window and the building connection.
In this respect, the ENERsign®primus is convincing in contrast to other suppliers, with its holistic, well thought-out design in accordance with the sound insulation requirements of being able to accommodate glass thicknesses without having to accept major losses in thermal insulation.
