alwitra daylight systems Light is playing an ever-increasing role in modern architecture, forming part of the design and aesthetics of a building. In particular, natural daylight offers many advantages: It is verified to have a positive physiological impact, it increases our wellbeing and thus enhances our productivity. In Germany, sufficient daylight for natural lighting is available between 8 am and 5 pm on 85 % of all days. For optimal daylight integration into architectural structures, specially developed constructional elements are required combining both technical and aesthetic...

alwitra kerbs are made of white impact-resistant "window quality" extruded polyvinyl chloride profiles. A special feature is the cellular system created by ribs that are formed already during the extrusion process of the profiles. This sophisticated technology gives you several advantages: • The cellular system itself ensures outstanding thermal insulation -without any additional "fillings". • When welding the corners, welding also includes the ribs. This results in a very large welded area providing high stability of the corners as well as continuous "thermal insulation", in particular, in...

Technical data Kerbs of all types Construction: Fire class: cellular system made of window-qua- white, through pigmentation lity extruded impact-resistant polyvinyl combination with alwitra rooflight Thermal properties: The kerb 1600 is 16 cm high, no taper- ing. This means a vertical inner wall, with the light opening size being the same as the roof opening size. Ensur- Light opening size = roof ing maximum daylight intake with a opening size modern design. • Tapering 00 mm • Vertical inner wall classic rooflights. This means an Light opening size = roof opening inclined inner wall, with...

Factory-fitted EVALON® or EVALASTIC® collar alwitra kerbs - as part of the alwitra flat roof system - can be supplied with a factory-fitted EVALON® or EVALASTIC® collar. This means that alwitra kerbs are already completely watertight and, after having been screwed to the substrate, need only to be welded to the installed waterproofing membrane on site. Technical data: Material: cut-to-size EVALON® or EVALASTIC® waterproofing membranes and preformed details, fully bonded to the kerbs over the entire height Thickness: 1.5 mm Absolutely no need for labour and time consuming detail work Colour:...
