Primary distinguishing advantages of the F50 Curtain Wall system are as follows.

High degree of thermal insulation 

Today, when prices for all types of energy resources are constantly rising, it is impossible to stay clear of problems related to environment and resource saving to create comfortable climate in a facility. To ensure good thermophysical and sound insulation of a building envelope, the LUMEN F50 series uses a set of thermal inserts (thermal insulators) made of hard impact-resistant polyvinyl chloride (PVC-U-HI) with high heat insulation parameters, co-extrusion sealant (patented solution) and a number of sealing gaskets based on ethylene-propylene rubber (EPDM). Due to optimal combination of these components the following thermal insulation parameters are provided (according to DIN 4108-4):.

Unlimited creative freedom and maximum entrance of light

CW 50

Curtain Wall 50 is a fa├žade and roof system that offers unlimited design freedom and allows maximum transparency. As such, CW 50 is available in several design and glazing variants, but also includes different technical variants to comply with specified levels of fire-resistance and thermal insulation. 

The design variants offer solutions for both the exterior and the interior of the building. The glazing variants range from using standard pressure plates, to structurally glazed and structurally clamped solutions. 

The extensive range of CW 50 profiles meets all requirements of contemporary architecture. With regard to the energetic performance, the system offers solutions in different levels, allowing the use of triple glazing and making the system even applicable for passive house or low energy 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, but also a flush roof vent for integration in roof applications of CW 50.
