Design flexibility

Flat glass atrium rooflights are a popular choice for architectural building design. The LAMILUX Glass Roof PR60 features virtually free shaping for atrium glass roof designs from pitches as low as 3° - making it possible to implement more or less any aesthetically pleasing and technically complex daylight construction. Offering choice and flexibility in glazing, ventilation and framework colour options, the LAMILUX Glass Roof PR60 is an architects dream product when specifying glass roofs

Technical properties

With trademark features including an attractive design, coupled with the highest level of airtightness and excellent heat-insulation values, the PR60 boasts architectural charm both aesthetically and with its technical properties. The glazing system is watertight tested on the slope to 1950 Pascals which means it is suitable for shallow pitch inclinations and guarantees no leaks in extremely high winds & driving rain. Effective soundproofing reduces the impact of unwanted noise to the interior and as standard the thermal engineering means it features excellent U-values, moreover, it is also available in a Passivhaus certified version

Glass Roof PR60 technical design characteristics

Energy efficiency

The Glass Roof PR60 is the mullion and transom glass roof system with optional ventilation. With aluminium profiles, the glazing system ensures maximum energy efficiency and thermal insulation. With high levels of wind and rain resistance, alongside enhanced isothermal characteristics in the overall construction – the unrivalled performance of this range results in no condensation alongside excellent air tightness values. The thermally broken “isothermally balanced” aluminium frames feature optimally aligned 10° isotherm line. This means that the thermally broken 10° isothermal line remains within the structure (see diagrams) for consistent heat insulation without any weak spots, reducing condensation, mould and bacteria. The Glass Roof PR60 also benefits from precision profiles incorporating Thermo Active Design which produces the smooth isothermal lines. TIP Total Insulated Product is certified in accordance with EN ISO 14021.
