Polytec 50 Aluminium Clad Curtain Walling
Passivhaus certified and CWCT tested REHAU Polytec 50 Curtain Walling is a composite stick system which offers a cost effective alternative to aluminium curtain walling. We have taken a triple strength approach to our system combining an aluminium exterior for an attractive design, a steel core for outstanding strength and structural capabilities, and internal PVCu for warmth and low maintenance.
REHAU Polytec 50 is a cutting-edge curtain walling system combining the properties of PVCu, aluminum and steel. This collaboration creates a triple strength glazing wall system that utilises each material’s benefits.
Curtain walling must withstand different load factors such as window and barrier loads, alongside the weight of the curtain walling itself. Strength is a key factor when fabricating these over-sized windows and REHAU’s load bearing curtain walling is designed with a high strength steel core, making it stronger when compared to aluminium (on a like for like basis).
When considering the degree of structural displacement under a given load, rigorous tests have proven that the Polytec 50 composite system is three times stronger than an entirely aluminium system.
With Passivhaus buildings becoming more and more popular, having a load bearing Passivhaus window solution is essential.
A curtain walling system needs to be robust to withstand severe weather conditions as well as have a high level of impact resistance.
Polytec 50 glazing walls achieve the following IFT Rosenheim Testing:
- Water Tightness 1950 Pa (BS EN 12155)
- Air Permeability 750 Pa (BS EN 12153)
- Wind Resistance 2000 Pa (BS EN 12179)
- Safety Test 3000 Pa (EN 13116)
- Impact Resistance Pass I5 / E5 (EN 14019)
Glazed facades can span large areas and can therefore be a common source of heat loss. The thermally efficient Polytec 50 Aluminium Clad Curtain Wall has recently been tested and certified to the CWCT performance tests with excellent results for wind resistance and water penetration and has been certified by the Passivhaus Institute in Germany for outstanding thermal performance (phA / phA+).
Polytec Curtain Walling can achieve a Uf Value as low as 0.74 W/m2K and Ucw Value of <0.8 W/m2K which means that less energy is needed to heat and cool a building, this saves money and helps lower the impact on the environment
REHAU engineers have specifically designed the Polytec 50 Curtain Walling system to achieve an exceptional sound rating allowing for a peaceful and comfortable internal environment.
At just 43dB, it’s the perfect choice for a huge variety of developments from luxury new builds to large commercial projects
Polytec 50 Curtain Walling has the popular external aesthetics of aluminium but with a steel core makes it a stronger alternative. Steel has an E-modulus three times greater than aluminium which allows the Polytec 50 curtain walling structural capabilities to easily outperform aluminium sections with the same geometry.
REHAU accommodates for variable static factors by offering a wide range of steel profiles and a corresponding selection of snap-on profiles to aesthetically enhance the product to your own requirements. The aesthetic advantages don’t stop there. It is a slim system with sightlines at just 50mm, this allows for more view and less window, letting plenty of light into the building. A variety of aluminium caps are available in hundreds of colours which gives flexibility to achieve the wall glazing exterior styling you require.
Polytec 50 Curtain Walling has a wide range of glazing sizes from 6 – 40mm and a maximum glazing weight of 180kg.
Stick curtain walling is used in many circumstances such as commercial windows, office windows, shop windows, stairwell glass and in domestic installations; with this in mind we have designed our screen walling system with an aluminium external face to give a polished look. This also allows for hundreds of different powder coating colour options. Aesthetics and building shading can be made even better when brise soleil systems are added.
Concept Wall 50 aluminium curtain walling
Unlimited creative freedom and maximum entrance of light
Curtain Wall 50 is a façade and roof system that offers unlimited design freedom and allows maximum transparency. CW 50 aluminium curtain wall is available in several design and glazing variants, but also includes different technical variants to comply with specified levels of thermal insulation.
The design variants offer curtain walls for both the exterior and the interior of the building. The glazing variants range from standard pressure plates, structurally glazed and structurally clamped facades.
The extensive range of CW 50 curtain walls meet all the requirements of contemporary architecture. With regard to energy performance, the curtain wall offers different solutions, allowing the use of triple glazing making the facade applicable for passive house or energy efficient buildings. In addition to that, dedicated opening types can also be seamlessly integrated; like a parallel opening window, a top hung window, a hidden vent turn and tilt window, also a flush roof vent for integration in roof applications of CW 50.
Concept Wall 60 aluminium curtain wall
Solution for heavy glass panes
Curtain Wall 60 is an excellent thermally insulated curtain wall system for robust constructions of large glass areas. CW 60 aluminium curtain wall can even be constructed as a sloped or curved facade. This modular curtain wall is intelligently designed with reinforced aluminium profiles, allowing the use of glass panels with weights of up to 450 kg.
CW 60 curtain wall meets the highest requirements in water- and air tightness, wind load resistance and thermal insulation. It is also able to integrate triple glazing.
This curtain wall is available in 4 different aesthetical exterior appearances. These different design options, together with the flush roof application, make CW 60 the perfect curtain wall for ultimate design freedom. In addition, CW 60 is made up of an extensive profile range and facilitates the integration of all types of window openings.
Concept Wall 65 ‘Element Façade’ aluminium curtain wall
Unitised façade system with maximum transparency
Curtain Wall 65-EF is a cost efficient curtain wall system for element façades with unique slender aesthetics, without compromising the extreme strength and stability required in high-rise constructions.
The typical characteristics of the unitised façade result in high execution speed on the building site, as its components are completely pre-assembled in the workshop. This high productivity embraces architectural aesthetics as the CW 65-EF works with slender profiles of only 65 mm.
CW 65-EF curtain wall meets the highest performance requirements in water- and air tightness and wind load resistance. The curtain wall system is available in different insulation levels, answering to the appropriate insulating requirement of the building. It also offers the possibility to integrate triple glazing.
CW 65-EF is available in two glazing variants, with unique aesthetical features: Cassette Glazing (CG) – this variant holds the glass using glazing beads, while the glass of the Structural Glazing (SG) variant is structurally bonded, offering a complete glass surface on the buildings exterior.
CW 65-EF can integrate various opening elements, such as a top hung and parallel opening windows.
Concept Wall 86 aluminium curtain wall
High execution speed
Curtain Wall 86 is an insulated aluminium curtain wall that complies with all requirements for large buildings. For these projects, speed of execution is of crucial importance. CW 86 curtain wall offers a special solution, where cassettes or elements can be pre-assembled in the workshop. On the building site, the cassettes can either be hooked on to a traditional stick structure (CW 86) or the façade can be built up element by element according to the modular curtain wall principle (CW 86-EF).
CW 86 is available in two glazing variants, with unique aesthetical features: Cassette Glazing (CG) – the variant holds the glass using glazing beads, while the glass of the Structural sealed Glazing (SG) variant is structurally bonded, offering a complete glass surface on the buildings exterior.
The energetic performance of the curtain wall is offered in different levels, providing thermally insulated profiles also for the Structural sealed Glazing. Specific drainage methods like cascade drainage lift this façade up to the highest demands in water- and air tightness, making the curtain wall suitable for extreme conditions such as coastal areas and buildings with high altitudes.
Besides the seamless integration of different types of windows, doors and sun screening systems, CW 86 offers motorised solutions for its opening elements, such as top hung and parallel opening windows, providing a total solution for the façade.
